Axial Compressor
An axial compressor is a gas compressor that can continuously pressurize gases. It is a rotating, airfoil-based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially. This differs from other rotating compressors such as centrifugal compressor, axi-centrifugal compressors and mixed-flow compressors where the fluid flow will include a "radial component" through the compressor. The energy level of the fluid increases as it flows through the compressor due to the action of the rotor blades which exert a torque on the fluid. The stationary blades slow the fluid, converting the circumferential component of flow into pressure. Compressors are typically driven by an electric motor or a steam or a gas turbine. Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiency and large mass flow rate, particularly in relation to their size and cross-section. They do, however, require several ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Re-engine
The aircraft design process is a loosely defined method used to balance many competing and demanding requirements to produce an aircraft that is strong, lightweight, economical and can carry an adequate payload while being sufficiently reliable to safely fly for the design life of the aircraft. Similar to, but more exacting than, the usual engineering design process, the technique is highly iterative, involving high-level configuration tradeoffs, a mixture of analysis and testing and the detailed examination of the adequacy of every part of the structure. For some types of aircraft, the design process is regulated by civil airworthiness authorities. This article deals with powered aircraft such as airplanes and helicopter designs. Design constraints Purpose The design process starts with the aircraft's intended purpose. Commercial airliners are designed for carrying a passenger or cargo payload, long range and greater fuel efficiency whereas fighter jets are designed to perform ...

European Aviation Safety Agency
The European Union Aviation Safety Agency (EASA) is an agency of the European Commission with responsibility for civil aviation safety in the European Union. It carries out certification, regulation and standardisation and also performs investigation and monitoring. It collects and analyses safety data, drafts and advises on safety legislation and co-ordinates with similar organisations in other parts of the world. The idea of a European-level aviation safety authority goes back to 1996, but the agency was legally established only in 2002; it began its work in 2003. History Based in Cologne, Germany, the agency was created on 15 July 2002 as the "European Aviation Safety Agency", and reached full functionality in 2008, taking over functions of the Joint Aviation Authorities. It was renamed the "European Union Aviation Safety Agency" in 2018. European Free Trade Association countries participate in the agency. The United Kingdom was a member until the end of the Brexit trans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AgustaWestland AW189
The AgustaWestland AW189 is a twin-engined, super-medium-lift helicopter manufactured by Leonardo S.p.A. It is derived from the AW149, and shares similarities with the AW139 and AW169. Development On 20 June 2011, development of the eight-tonne twin-engine AW189 was formally announced by AgustaWestland at the Paris International Air Show; at the time, the company planned to have the new rotorcraft certified by 2013 and in service in 2014. The AW189 is a civil-orientated version of the military AW149, which in turn is an enlarged development of the AW139; in 2011, AgustaWestland CEO Bruno Spagnolini stated that: "The AW139 and the AW189 are two very different aircraft but they both share the same general concept in architecture". AgustaWestland stated it aimed to sell the AW189 for offshore helicopter support, search and rescue (SAR), and passenger transport roles.
