Aft Pressure Bulkhead
The aft pressure bulkhead or rear pressure bulkhead is the rear component of the pressure seal in all aircraft that cruise in a tropopause zone in the Earth's atmosphere. It helps maintain pressure when stratocruising and protects the aircraft from bursting due to the higher internal pressure. Design Aft pressure bulkheads can either be curved, which reduces the amount of metal needed at the cost of reducing the usable space in the airliner, or flat, which gives more internal space but also more weight. Patents have been filed that propose deliberately creating cavities within the rear bulkhead with the purpose of providing more usable cabin space. On several airliners, production of the rear pressure bulkhead has been outsourced to third party manufacturers. While typically being a time-consuming and somewhat uncommon process, an aircraft's aft pressure bulkhead can be wholly replaced. During the twenty-first century, various parties became increasingly interested in developing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shuttle Carrier Aircraft Interior Bulkhead
The original meaning of the word shuttle is the Shuttle (weaving), device used in weaving to carry the weft. By reference to the continual to-and-fro motion associated with that, the term was then applied in transportation and then in other spheres. Thus the word may now also refer to: Transport Air transport * Air shuttle, a type of flight which quickly connects nearby destinations * Delta Shuttle, the brand name for Delta Air Lines' air shuttle service * Rossi Shuttle Quik, an Italian ultralight trike design * Shuttle America, a regional airline based in Indianapolis, Indiana * Shuttle by United, a regional airline operated as a subsidiary of United Airlines * Shuttle Carrier Aircraft, modified Boeing 747 airliners used to transport Space Shuttle orbiters * US Airways Shuttle, the brand name for an hourly service offered by US Airways * The call sign for domestic (UK internal) British Airways flights - international flights use Speedbird Land transport Automotive brands * Fit ...

Premium AEROTEC
Premium AEROTEC is a German aerospace manufacturing business, headquartered in Augsburg in Germany. It is a subsidiary of Airbus. The company was created in September 2008 as a spin off from the multinational aerospace group EADS, which subsequently rebranded itself as Airbus Group. While a large portion of Premium AEROTEC's business has been derived from its parent company, it has also forged partnerships with other manufacturing groups, including Dassault Aviation, Vought and Latécoère. The company has positioned itself as a Tier One supplier of aerostructures, which it produces at its facilities in Germany and Romania. History Prior to its establishment as an individual entity, the assets of Premium AEROTEC principally existed within the multinational aerospace group EADS. Its independence came as a consequence of several economic factors affecting the business; during 2007, EADS' management decided to respond to events, such a weakening US dollar and the high investmen ...

Tailstrike
In aviation, a tailstrike or tail strike occurs when the tail or empennage of an aircraft strikes the ground or other stationary object. This can happen with a fixed-wing aircraft with tricycle undercarriage, in both takeoff where the pilot rotates the nose up too rapidly, or in landing Landing is the last part of a flight, where a flying animal, aircraft, or spacecraft returns to the ground. When the flying object returns to water, the process is called alighting, although it is commonly called "landing", "touchdown" or " spl ... where the pilot raises the nose too sharply during final approach, often in attempting to land too near the runway threshold. It can also happen during helicopter operations close to the ground, when the tail inadvertently strikes an obstacle. A minor tailstrike incident may not be dangerous in itself, but the aircraft may still be weakened and must be thoroughly inspected and repaired if a more disastrous accident is to be avoided later in it ...

Catastrophic Failure
A catastrophic failure is a sudden and total failure from which recovery is impossible. Catastrophic failures often lead to cascading systems failure. The term is most commonly used for structural failures, but has often been extended to many other disciplines in which total and irrecoverable loss occurs, such as a head crash occurrence on a hard disk drive. For example, catastrophic failure can be observed in steam turbine rotor failure, which can occur due to peak stress on the rotor; stress concentration increases up to a point at which it is excessive, leading ultimately to the failure of the disc. In firearms, catastrophic failure usually refers to a rupture or disintegration of the barrel or receiver of the gun when firing it. Some possible causes of this are an out-of-battery gun, an inadequate headspace, the use of incorrect ammunition, the use of ammunition with an incorrect propellant charge, a partially or fully obstructed barrel, or weakened metal in the barrel o ...

Japan Air Lines Flight 123
Japan Air Lines Flight 123 was a scheduled domestic passenger flight from Tokyo to Osaka, Japan. On August12, 1985, the Boeing 747 flying the route suffered a severe structural failure and explosive decompression 12 minutes after takeoff. After flying under minimum control for 32 minutes, the plane crashed in the area of Mount Takamagahara, 100kilometres () from Tokyo. The aircraft, featuring a high-density seating configuration, was carrying 524people. The crash killed all 15crew members and 505 of the 509 passengers on board, leaving only four survivors. An estimated 20 to 50 passengers survived the initial crash but died from their injuries while awaiting rescue. The crash is the list of aircraft accidents and incidents resulting in at least 50 fatalities, deadliest single-aircraft accident in aviation history and remains the deadliest aviation incident in Japan. Japan's Aircraft Accident Investigation Commission (AAIC), assisted by the U.S. National Transportation Safety Boar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British European Airways Flight 706
British European Airways Flight 706 (BE706/BEA706) was a scheduled international passenger flight from London, England to Salzburg, Austria. On 2 October 1971, whilst en route at , the Vickers Vanguard the pressure bulkhead at the rear of the cabin failed. The resulting depressurisation of the tail section caused the surfaces of the tailplanes to separate. The aircraft entered an uncontrollable dive and crashed near Aarsele, Belgium, killing all 63 passengers and crew on impact. A piece of debris from the aircraft struck a passing car, causing minor injuries to one of its occupants. The British AAIB concluded that the failure of the rear pressure bulkhead had been caused by undetected corrosion located at the rear of the aircraft. The corrosion could not be noticed by crew due to the inspection technique that had been applied by BEA. Numerous pressurization cycles caused the crack to grow, weakening the rear pressure bulkhead until the structure was unable to withstand further ...

Thermoplastic
A thermoplastic, or thermosoftening plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. Most thermoplastics have a high molecular weight. The polymer chains associate by intermolecular forces, which weaken rapidly with increased temperature, yielding a viscous liquid. In this state, thermoplastics may be reshaped, and are typically used to produce parts by various polymer processing techniques such as injection molding, compression molding, calendering, and extrusion. Thermoplastics differ from thermosetting polymers (or "thermosets"), which form irreversible chemical bonds during the curing process. Thermosets do not melt when heated, but typically decompose and do not reform upon cooling. Above its glass transition temperature and below its melting point, the physical properties of a thermoplastic change drastically without an associated phase change. Some thermoplastics do not fully ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aircraft
An aircraft ( aircraft) is a vehicle that is able to flight, fly by gaining support from the Atmosphere of Earth, air. It counters the force of gravity by using either Buoyancy, static lift or the Lift (force), dynamic lift of an airfoil, or, in a few cases, direct Powered lift, downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), Glider (aircraft), gliders, Powered paragliding, paramotors, and hot air balloons. Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air." The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Aircrew, Crewed aircraft are flown by an onboard Aircraft pilot, pilot, whereas unmanned aerial vehicles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
