An aircraft flight control system combines mechanical and electronic equipment that ensures exceptional precision and reliability in controlling an in-flight aircraft. It consists of primary, secondary, and auxiliary systems, wherein primary flight control systems are used to control ailerons, elevators,...
primary purpose of an aircraft APU is to start the aircraft's main engines, but it is not limited to this function. The unit also provides electrical and pneumatic power for ground operations such as lighting, de-icing, air conditioning or heat for cabin comfort, airplane controls and press...
A primary task of the CAA has been the certification of aircraft to the code published in the British Civil Airworthiness Requirements (BCARs). However, great changes are taking place within Europe which have led to revision of the scheme of things. Most European countries have grouped together...
Manual wet lay-up composite patches have been used for some time on secondary aircraft structure but these are slow to apply and for the resin to cure. The use of precured composite patches is more reliable for primary aircraft structure, which are quicker to apply and for the resin to ...
后三点尾轮式与后三点尾橇式起落架 Though the tricycle arrangement may be most popular today, that was not always the case. The tailwheel undercarriage dominated aircraft design for the first four decades of flight and is still widely used on many small piston-engine planes.虽然前三点起落架...
commercial transport builders, Boeing, Douglas, and Lockheed. The purpose of the program is to develop the technology and confidence that will enable the builders to commit to extensive use of composite structure on future transport aircraft. Six components, three secondary, and three primary ...
New instruments such as the Geostationary Lightning Mapper (GLM) expand the observing toolbox with novel products that are being used in both the TC forecast and research communities. This section will focus on just some of the primary ways that GOES-R Series imagery and products are being ...
A primary structure of an aircraft power plant support pylon is disclosed having a bottom stringer and two lateral walls formed in a single piece or welded so as to form a U-shaped
