Airplanes And Aircraft Engineering Essay

Airplanes And Aircraft Engineering Essay Aircrafts are capable of flight using forward motion that generates lift as the wing moves through the air. Airplane is propelled by a screw propeller or a high-velocity jet, and supported by the dynamic reaction of the air against its wings. There are many components of an airplane however the essential components are a wing system to sustain it during flight, tail surfaces to stabilize the wing, movable surfaces to control the attitude of the machine in flight, and a power plant to provide the thrust to push the craft through the air. An enclosed body which is known as the fuselage houses the crew, passengers, and cargo, as well as the controls and instruments used by the navigator. An airplane also requires a support system when it is at rest on a surface and during takeoff and landing. Airplanes have different shapes and sizes depending on the purpose, but the modern airplanes have some features in common. They are fuselage, tail assembly and control surfaces, wing, power-plant and landing gear. In this report the prime focus is on the Prime components of the aircraft assuring structural integrity while meeting requirements for optimum operational performance of an aircraft. The empennage is also known as the tail is the rear part of the aircraft. Usually it includes the stabilizers, rudder and elevator as many other components as seen below.. It is constructed depending on the aircraft for example in fighter jets it may be constructed around the exhaust nozzle. In commercial aircrafts the empennage is built from the cabin pressure-cone and may contain the Flight Data Recorder (black box), Cockpit Voice Recorder and the pressure out-flow valve. There is another design which does not require an elevator. In this design there is a one-piece horizontal stabilizer that pivots from a central hinge point, such a design is known as a stabilator. 2. Wings: As we can see below is a wing. Wings are airfoils attached to each side of the fuselage and are the main lifting surfaces that help the airplane during flight. There are great variations in the wing designs, sizes, and shapes used by the various manufacturers. Each of these specifications fulfils a certain need with respect to the performance for an airplane. Wings may be attached at the top, middle, or lower portion of the fuselage and are referred to as high-, mid-, and low-wing, respectively. The number of wings may vary. Monoplanes contain a single set of wings while those with two sets are called Biplanes. The principal structural parts of the wing are SPARS, RIBS, and STRINGERS. These are reinforced by trusses, I-beams, tubing, or other devices, including the skin. The wing ribs determine the shape and thickness of the wing (airfoil). Attached to the rear, or trailing, edges of the wings are two types of control surfaces referred to as ailerons and flaps. http://khup.com/view/2_keyword-design-of-aircraft-rib-structure/aircraft-structure.html 2.1 Spars 2.1.1. Definition: The spar is the main structural member of the wing, in a fixed-wing aircraft, running span wise at right angles to the fuselage. There may be more than 1 spar or none at all. 2.1.2 Uses: Fight loads and the weight of the wings whilst on the ground is carried by spars. Spars are also used in aerofoil surfaces such as the tail plane, fin and serve a similar function, although the loads transmitted may be different. 2.1.3. Loads: Upward bending loads from the wing lift force that supports the fuselage in flight. Downward bending loads due to the weights acting. Drag loads dependent on airspeed and inertia. Rolling inertia loads. Chordwise twisting loads due to aerodynamic effects at high airspeeds. 2.1.4. Materials: Wooden construction Early aircraft used spars carved from solid Spruce or Ash. Wooden spar types have been used and tried with such as spars which are box-section in form; or laminated spars which are laid up in a jig, and compression glued to retain the wing dihedral. Wooden spars are still being used in light aircraft such as the Robin DR400. Metal spars A common metal spar in a general aviation aircraft generally consists of a sheet aluminium spar web, with L or T -shaped spar caps being welded or riveted to the top and bottom of the sheet to prevent buckling under applied loads. Tubular metal spars The German Junkers J.I armoured fuselage ground-attack sesquiplane of 1917 used a Hugo Junkers -designed multi-tube network of several tubular wing spars, placed just under the corrugated duralumin wing covering and with each tubular spar connected to the adjacent one with a space frame of triangulated duralumin strips riveted onto the spars. Advantages Gives substantial increase in structural strength at a time when most other designs were built with wood-structure wings. Geodesic construction In aircraft such as the Vickers Wellington, a geodesic wing spar structure was employed which had the advantages of being lightweight and able to withstand heavy battle damage with only partial loss of strength. Composite construction Nowadays aircraft use carbon fibre and Kevlar in their construction, ranging in size from large airliners to small aircraft. Companies have employed solid fibreglass spars in their designs but now often use carbon fibre in their high performance gliders such as the ASG 29 Advantages The increase in strength and reduction in weight compared to the earlier fibreglass-sparred aircraft allows a greater quantity of water ballast to be carried. 2.1.5. Disadvantages: The wooden spar has a danger of the deteriorating effect that atmospheric conditions, both dry and wet, and biological threats such as wood-boring insect infestation and fungal attack can have on the wooded spars; consequently regular inspections are often mandated to maintain airworthiness. Similar disadvantages on metal spars limit their use. 2.2 Ribs 2.2.1. Definition: In an aircraft,  ribs  are forming elements of the structure of a  wing. Ribs are attached to the main  spar, and by being repeated at frequent intervals they form a skeletal shape. Usually ribs incorporate the  airfoil  shape of the wing. They are the cross-section shape of a wing. The ribs can be classified according to the types of load acting on it. Lightly loaded ribs are subjected to aerodynamic loads while a rib is subjected to concentrated forces transferred from primary points is considered as moderately loaded rib. 2.2.2 Function: Maintain the sectional shape of wing box. Function as panel breakers for stringers. Provide support for attachment of other systems. Distribute locally applied air pressure loads. 2.2.3. Stiffness: The ribs contribute little to the overall stiffness of the wing box and also carry little of global bend and twist loads acting on the wing. 2.2.4. Loads: Loads acting on the ribs are of three types: Loads transmitted from the skin-stringer wing panels. Concentrated forces transmitted to the rib due to landing gear connections, power plants nacelle connections, etc Body forces in the form of gravitational forces. Inertia forces due to wing structural mass. 2.2.5. Materials: Ribs are made out of wood, metal, plastic, composites, foam. Carbon reinforced composites (CFC) or Carbon Fibre Reinforced Plastics (CFRP) are used extensively in aircraft structures as they give high stiffness and strength with lower weight. 2.2.6. Advantages and Disadvantages: Wooden ribs are subjected to atmospheric deterioration. http://khup.com/view/2_keyword-loads-acting-on-ribs/report-5.html 2.3. Stringers or Longerons Interior of a Boeing/ Stearman PT-17 showing small channel section stringers. 2.3.1. Definition: A longeron  or  stringer  or  stiffener  is a thin strip of wood, metal or carbon fibre, to which the skin of the aircraft is fastened. Longerons are attached to  formers  in the case of the fuselage, or  ribs  in the case of a wing, or  empennage. In early aircraft, a fabric covering was sewn to the longerons, and then stretched tight by painting it with  dope, which would make the fabric shrink, and become stiff. 2.3.2. Properties: Longeron and stringer are used interchangeably. If the longitudinal members in a fuselage are less in number (usually 4 to 8), they are called longerons. The longeron system requires that the fuselage frames be closely spaced (about every 4 to 6 in/10 to 15 cm). If the longitudinal members are numerous (usually 50 to 100) then they are called stringers. In the stringer system the longitudinal members are smaller and the frames are spaced farther apart (about 15 to 20 in/38 to 51 cm). Longerons are of larger cross-section when compared to stringers. 2.3.3. Advantages: On modern aircraft the stringer system is more common because its more weight efficient despite being complex to construct and analyze. Some aircraft, use a combination of both stringers and longerons. The stringers carry bending moments and axial forces. They also stabilize the thin fuselage skin. 3. Power Plant: A power plant consists of propeller and engine.   The main function of the engine is to supply power to run the propeller. It also generates electrical power, provides vacuum source for flight instruments, and provides a source of heat for the pilot and passengers. The engine is covered by a cowling, or in some airplanes, surrounded by a nacelle. Its purpose is to streamline the flow of air around the engine and to help cool the engine by ducting air around the cylinders. The propeller on the front of the engine converts the rotating force of the engine into forward acting force called thrust that helps move the airplane through the air. 4. Landing gear: Every matter has its base on which it stands. The principle support of the airplane when parked, taxiing, taking off, or when landing is its landing gear. The most common type of landing gear consists of wheels, but airplanes can also be equipped with floats for water operations, or skis for landing on snow. The landing gear consists of three wheels two main wheels-tail wheels and a third wheel positioned either at the front or rear of the airplane-nose wheel, the design is referred to as a tricycle gear A steerable nose wheel or tail wheel permits the airplane to be controlled throughout all operations while on the ground.    5. Fuselage Fuselage is aircrafts main body and covers the majority of the airplane, it holds all other pieces of the aircraft together and other large components are attached to it. The fuselage is generally streamlined to reduce drag. Designs for fuselages vary widely. The fuselage houses the cockpit where the pilot and flight crew sit and it provides areas for passengers and cargo. Some aircraft carry fuel in the fuselage; others carry the fuel in the wings. 5.1. Types of Fuselage Structures: Truss Structure Geodesic construction Monocoque Shell Semi-monocoque 5.5.1. Truss Structure: This kind of structure is used in lightweight aircraft using welded steel tube trusses. A box truss fuselage structure can also be built out of wood-covered with plywood. 5.1.2. Geodesic construction: Geodesic structural elements used by during the wars, World War II, to form the whole of the fuselage, including its shape. In this multiple flat strip stringers are wound about the formers in opposite spiral directions, giving a basket-like appearance. This proved to be light, strong, and rigid and had the advantage of being made almost entirely of wood. Its redundant structure can survive localized damage without catastrophic failure. 5.1.3. Monocoque Shell In this method, the exterior surface of the fuselage is also the primary structure. A typical early form of this built using moulded plywood, where the layers of plywood are formed over a plug or within a mould. A later form of this structure uses fibreglass cloth impregnated with polyester or epoxy resin, instead of plywood, as the skin. A simple form of this used in some amateur-built aircraft uses rigid expanded foam plastic as the core, with a fibreglass covering, eliminating the necessity of fabricating moulds, but requiring more effort in finishing. An example of a larger moulded plywood aircraft is the de Havilland Mosquito fighter/light bomber of World War II. No plywood-skin fuselage is truly monocoque, since stiffening elements are incorporated into the structure to carry concentrated loads that would otherwise buckle the thin skin. The use of moulded fibreglass using negative (female) moulds (which give a nearly finished product) is prevalent in the series production of ma ny modern sailplanes. 5.1.4. Semi-monocoque. This is the preferred method of constructing an all-aluminium fuselage. First, a series of frames in the shape of the fuselage cross sections are held in position on a rigid fixture, or jig. These frames are then joined with lightweight longitudinal elements called stringers. These are in turn covered with a skin of sheet aluminium, attached by riveting or by bonding with special adhesives. The fixture is then disassembled and removed from the completed fuselage shell, which is then fitted out with wiring, controls, and interior equipment such as seats and luggage bins. Most modern large aircraft are built using this technique, but use several large sections constructed in this fashion which are then joined with fasteners to form the complete fuselage. As the accuracy of the final product is determined largely by the costly fixture, this form is suitable for series production, where a large number of identical aircraft are to be produced. Both monocoque and semi-monocoque are referred to as stressed skin structures as all or a portion of the external load (i.e. from wings and empennage, and from discrete masses such as the engine) is taken by the surface covering. In addition, the entire load from internal pressurization is carried (as skin tension) by the external skin. As stated above we are now familiar with the prime components of an airplane. Now let us get into detail, and understand the components such as the bulkhead, Frames, Ribs, Spars, Stringers (Longerons), and Skins. 5.2. BULKHEADS 5.2.1. Definition: A bulkhead is the physical partition that divides a plane or a fuselage into different classes or sections. Typically, a bulkhead is a wall but can also be a curtain or screen. In addition to separating classes from one another, i.e. business and economy, bulkheads can be found throughout the plane, separating the seats from the galley and lavatory areas. Bulkheads also contribute to the structural stability and rigidity of a craft. 5.2.2. Uses: 5.2.3. Loads: 5.2.4. Materials: 5.3. FRAMES 5.3.1. Definition: The airframe provides the structure to which all other components are attached. Airframes may be welded tube, sheet metal, composite, or simply tubes bolted together. A combination of construction methods may also be employed. The airframes with the greatest strength-to-weight ratios are a carbon fibre material or the welded tube structure, which has been in use for a number of years. 5.3.2. Uses: 5.3.3. Loads: 5.3.4. Materials: Material Selection Material Usage Advantages Disadvantages High strength unidirectional graphite/epoxy Spar caps High strength, low weight High cost, low impact resistance, difficult to manufacture High modulus  ±45 ° graphite/epoxy Skin (w/foam core), Shear web, Wing ribs High strength, low weight, low surface roughness, stealth characteristics High cost, low impact resistance, difficult to manufacture Aluminum 7075-T6 Bulkheads, Longerons Low cost, ease of manufacture, good sturctural efficiency Low strength, not weldable Stainless steel (AM-350) Landing gear Relatively low cost, high strength, corrosion resistance High weight Nickel (Hastelloy B) Nozzles and ducting Temperature resistance Low structural resistance Kevlar Internal armor High strength, low weight, high impact resistance High cost, difficult to manufacture

Charities Essay

The legal definition of charity has historically been somewhat elusive and stands distinct from any understanding of charity in a general or popular sense. As Lord Wright observed, in its legal sense the word â€Å"charitable is a word of art, of precise and technical meaning†[1]. Viscount Simmonds further remarked that, â€Å"no comprehensive definition of legal charity has been given either by legislature or in judicial utterance, there is no limit to the number and diversity of ways in which man will seek to benefit his fellow men†. The Preamble to the Charitable Uses Act 1601, also referred to as the Statute of Elizabeth I, contained a list of purposes which were then regarded as charitable. It assumed a central role for the courts as a reference point or catalogue of accepted instances of charity until almost 300 years later when Lord MacNaughten in the Pemsel case, famously classified charitable objects into four principal divisions: (i) trusts for the relief of poverty, (ii) trusts for the advancement of education, (iii) trusts for the advancement of religion, (iv) trusts beneficial to the community not falling under any of the preceding heads. These four heads of charity were used as reference whenever the inherent charitable nature of a purpose or institution was questioned until the Charities Act 2006 received royal assent. Section 2(2) of the 2006 Act now provides a modern statutory definition of charity by listing 13 descriptions of purposes deemed charitable at law. In order to be charitable, an organisation has to be established for one or more purposes within the descriptions recognised by the law as capable of being charitable, and for the public benefit. Charity law in England and Wales has developed within the context of the traditional monotheistic religions but it has embraced for many years religions other than Christianity and Judaism. In Bowman[3], Lord Parker effectively held that it was not just the promotion of Christianity that would be recognised but that the Courts of this country were not precluded â€Å"from giving effect to trusts for the purposes of religions which, however sacred they may be to millions of His Majesty’s subjects, either deny the truth of Christianity or, at any rate, do not accept some of its fundamental doctrines†. Furthermore in the Commission’s Scientology[4] decision it was firmly established that â€Å"The law does not prefer one religion to another and as between religions the law stands neutral†[5]. The English courts have, for a long time, resisted closely defining what makes some belief systems religious and others not. However in the Scientology case, the Commissioners accepted that there are various characteristics of religion which can be discerned from the legal authorities: †¢ Belief in a god or a deity or supreme being – R v Registrar General[6] †¢ Two of the essential attributes of religion are faith and worship: faith in a god and worship of that god – South Place Ethical Society[7] †¢ To advance religion means â€Å"to promote it, to spread the message ever wider among mankind; to take some positive steps to sustain and increase religious belief and these things are done in a variety of ways which may be comprehensively described as pastoral and missionary†. United Grand Lodge v Holborn BC[8]. Having considered these characteristics, the Commissioners concluded that the definition of a religion in English charity law was characterised by a belief in a supreme being and an expression of that belief through worship. This definition is further refined in the 2006 Act where s2 (3) a gives a partial definition of the word religion. However, the law does not automatically recognise as a religion everything that may designate itself as a religion and there are some principles to which a purpose must conform if it is to be regarded as within the Charities Act’s description of ‘the advancement of religion’. These general principles are gathered from the common law of England and Wales but also take into account the body of law which has developed concerning the European Convention right to freedom of thought, conscience and religion. As a general proposition, for its advancement to be capable of being charitable in this context, a religion should have a certain level of cogency, seriousness, coherence and importance[9]. Also, in order to be charitable for the advancement of religion, the content of any system of faith and worship has to be of a positive nature, impacting beneficially on the community. Sir John Wickens, V-C. in Cocks v Manners[10] observed: â€Å"It is said, in some of the cases, that religious purposes are charitable, but that can only be true as to religious services tending directly or indirectly towards the instruction or the edification of the public†¦Ã¢â‚¬  Hence, to be charitable a religious purpose has to be serious, tend directly or indirectly to the moral and spiritual improvement of the public as well as being for the public benefit. In Holmes v Attorney General[11] Walton J commented: â€Å"†¦ It is not for the benefit of the adherents of the religion themselves that the law confers charitable status, it is in the interests of the public. † Hence, as a general proposition, in the case of charities for the advancement of religion the purpose must not simply be for the benefit of the followers of the particular religion. Formerly, the proposition stated that â€Å"as between different religions the law stands neutral, but it assumes that any religion is at least likely to be better than none†[12]. Plowman J in Re Watson[13] considered a case for the publication and distribution of the fundamentalist Christian writings of an individual where he quoted authority that the court does not prefer one religion or sect to another and said that â€Å"where the purposes in question are of a religious nature †¦ then the court assumes a public benefit unless the contrary is shown†. He then went on to say that the only way of disproving a public benefit is to show that the doctrines inculcated are adverse to the very foundations of all religion, and that they are subversive of all morality. However, that part of the judgment being inconsistent with the judgment of the court of appeal and opinions given by the House of Lords in Gilmour v Coats, where it was held: â€Å"†¦the question whether a trust is beneficial to the public is an entirely different one from the question whether a trust is for the advancement of religion†, it is not regarded a binding. Since the Charities Act 2006, there is no longer any presumption that, because a purpose falls within the description â€Å"the advancement of religion†, it is for the public benefit. Section 3(2) of the Act provides: â€Å"In determining whether [the public benefit] requirement is satisfied in relation to any †¦purpose, it is not to be presumed that a purpose of a particular description is for the public benefit†. Hence, with the removal of the presumption and in the modern context the proposition may now be interpreted as meaning that advancing religion can be seen as a public good if such advancement can be demonstrated to be in relation to a system having a benign and positive content which is being advanced for the benefit of the public. Over the years, there are some purposes which, despite being beneficial and religious and indeed seriously religious, did not fall within the legal framework. For example, fostering private piety, although being a religious activity, is not a charitable purpose due to the absence of benefit to the public. In Cocks v Manners[14] (supra) it was said that â€Å"a voluntary association of women for the purpose of working out their own salvation by religious exercises and self-denial seems to have none of the requisites of a charitable institution. † In the Re Joy[15] case it was held that the real object contemplated by the testator was the non-charitable purpose of improvement of the membership of a society by prayer. Further, in Re White[16], it was held that â€Å"a society for the promotion of private prayer and devotions by its own members and which has no wider scope, no public element, and no purpose of general utility would not be charitable†. Lord Simonds in the Gilmour[17] case later confirmed the decision in Cocks v Manners and said that activities â€Å"good in themselves but solely designed to benefit individuals associated for the purpose of securing that benefit, which may not have some repercussions or consequential effects beneficial to some section of the general community† do not meet the prerequisites of a charitable institution. In Re Warre’s Will Trusts, on the matter of a retreat house, Harman J said: â€Å"Activities which do not in any way affect the public or any section of it are not charitable. Pious contemplation and prayer are, no doubt, good for the soul, and may be of benefit by some intercessory process, of which the law takes no notice, but they are not charitable activities. † Thus, in Re Hetherington[18] it was held that the celebration of a religious rite in private does not contain the necessary element of public benefit since any benefit of prayer or example is incapable of proof in the legal sense and any element of spiritual or moral improvement (edification) is limited to a private not public class of those present at the celebration. However, in the same case it was also held that the holding of a religious service which is open to the public is capable of conferring a â€Å"sufficient public benefit because of the edifying and improving effect of such celebration on the members of the public who attend. † There are also other purposes related to religion whose pursuits have not been considered as charitable because the purpose itself is not exclusively charitable. For example a trust ‘for Roman Catholic purposes’ may not be for exclusively charitable purposes furthering the Roman Catholic faith[19]. Also a gift to an Anglican vicar of a parish â€Å"for parochial institutions or purpose†Ã¢â‚¬â„¢[20] was not considered charitable. A bequest to an archbishop to be applied â€Å"in any manner he might think best for helping to carry on the work of the Church in Wales†[21] is not charitable either and neither is a generally stated purpose â€Å"for religious, educational and other parochial requirements†[22]. On the other hand, In Re Schoales[23], it was clarified that there is no distinction, from the point of view of validity as a gift for charitable purposes, between a gift to the Church of England and a gift to another Church. A gift for the general purposes of a particular church or denomination or faith community falls are considered in law as a gift which has to be applied only for such of its purposes as are for the advancement of religion for the public benefit, and hence charitable. As mentioned above, charitable purposes require some promotion or advancement that is to â€Å"spread its message ever wider among mankind; to take some positive steps to sustain and increase religious belief†[24]. Proselytising is one way of advancing religious purposes[25] but it may raise public benefit issues if it breaks the law or results in harm or detriment. Therefore, it would not be compatible with public benefit principles for an organisation to seek to inhibit anyone from their rights of freedom of thought, conscience or religion (Article 9 ECHR) and to manifest or change such beliefs. This matter was considered in Kokkinakis v Greece[26] and the court in considering attempts to forbid activities of a Jehovah’s Witness confirmed that a democratic society has a plurality of beliefs and held that freedom to manifest one’s religion includes the right to convince one’s neighbor. But, the court drew a clear distinction between bearing Christian witness and improper proselytism by stating that the former was true evangelism and the latter representing a corruption or deformation of it. Furthermore, proselytising being unlawful in some countries, the Commission dealt with the issue of whether it was possible to recognise a religious purpose as charitable in England and Wales which is not charitable and may be illegal abroad in its annual report in 1993 which mentioned: â€Å"One should first consider whether they would be regarded as charities if their operations are confined to the United Kingdom. If they would, then they should be presumed also to be charitable even though operating abroad unless it would be contrary to public policy to recognise them. Hence, an organisation whose purpose is to proselytize, even if its activity is carried out internationally, may be charitable in England and Wales unless it causes harm or detriment which outweighs the public benefit. The High Court considered the statement in the Sonsino case[27] in 2002 and upheld it. However, it still remains unclear as to what the courts would rule contrary to public policy. Another way of advancing a religion would be by means of undertaking pastoral work. However, where a charity is operating solely for the purpose of advancement of religion, then any secular pastoral work which it undertakes should be as a means of advancing the particular religion. A convent in Cocks v Manners[28] was held charitable and there the nuns were engaged in exterior works (teaching the ignorant and nursing the sick) as part of their religious work. In the United Grand Lodge[29] case, Donovan J said that taking positive steps to sustain and increase religious beliefs was something done â€Å"in a variety of ways which can be comprehensively described as pastoral and missionary†. More recently, the Pilsdon Community House, a religious community living according to Christian principles and giving practical help in cases of drug addiction, drink, having been in prison or loneliness was considered in Re Banfield[30]. The court held that the fact that a religious community makes its services available to those of all creeds and of none does not prevent it being a charity for the advancement of religion also that furthering the purposes of the community amounted to the advancement of religion.

Hip Hop, By Maya Angelou Essay - 1432 Words

Mos Def’s â€Å"Hip-Hop† and Maya Angelou’s â€Å"Africa†: Identities That Have Been Exploited Many people find identity in their culture, art and literature. Both in Maya Angelou’s â€Å"Africa† and Mos Def’s â€Å"Hip-Hop† both have themes of identity and exploitation. Both show that the black experience in the Americas and mostly all over the world is based on being the one’s who are exploited. Both poems have to do with one’s identity or autonomy being stolen from them. They do differ when it comes to the genre and the context but they do share the themes of identity and exploitation. Angelou in her poem uses the examples of the slave trade and using a women to convey two different means of exploitation. Her poem can even connect towards today, where Africa is still being exploited for its natural resources. Def’s song has to do with mainly a commentary of hip-hop as a genre and a culture. This song jam packs a myriad of subject matters such as history, progression, warnings, friendship, perfection, and identity. Def in a song that should seem like a celebration for hip-hop, instead criticizes it for it’s exploitive nature. In both poems you could get to hear the voice of the exploited. Agelou in â€Å"Africa† seems to be describing a women writing, â€Å"Thus she lain. Sugar cane sweet†. The first two lines could imply that women are sweet.
