The first mechanically powered submarine, the 1863 French submarine Plongeur, used a compressed-air engine. Musée de la Marine (Rochefort). A pneumatic motor (air motor), or compressed-air engine, is a type of motor which does mechanical work by expanding compressed air. Pneumatic motors generally convert the compressed-air energy to ...
Pneumatics (from Greek πνεῦμα pneuma 'wind, breath') is the use of gas or pressurized air in mechanical systems. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other ...
At least two engines provide compressed bleed air for all the plane's pneumatic systems, to provide full redundancy. Compressed air is also obtained from the auxiliary power unit (APU), if fitted, in the event of an emergency and for cabin air supply on the ground before the main engines are started. Most modern commercial aircraft today have ...
In aeronautics, an environmental control system (ECS) of an aircraft is an essential component which provides air supply, thermal control and cabin pressurization for the crew and passengers. Additional functions include the cooling of avionics , smoke detection , and fire suppression .
An aircraft engine, often referred to as an aero engine, is the power component of an aircraft propulsion system. Aircraft using power components are referred to as powered flight . [ 1 ] Most aircraft engines are either piston engines or gas turbines , although a few have been rocket powered and in recent years many small UAVs have used ...
Aircraft flight control systems – A conventional fixed-wing aircraft flight control system consists of flight control surfaces, the respective cockpit controls, connecting linkages, and the necessary operating mechanisms to control an aircraft's direction in flight. Aircraft engine controls are also considered as flight controls as they ...
Derived from the words hydraulics and pneumatics, pneudraulics is the term used when discussing systems on military aircraft that use either or some combination of hydraulic and pneumatic systems. The science of fluids made of both gas and liquid.
An aircraft fuel system is designed to store and deliver aviation fuel to the propulsion system and auxiliary power unit (APU) if equipped. Fuel systems differ greatly due to different performance of the aircraft in which they are installed. [6] [7]
