Propeller
A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and ...

Intake ramp
An intake ramp is a rectangular, plate-like device within the air intake of a jet engine, designed to generate a shock wave to aid the inlet compression process at supersonic speeds. The ramp sits at ...

Contra-rotating
Contra-rotating, also referred to as coaxial contra-rotating, is a technique whereby parts of a mechanism rotate in opposite directions about a common axis, usually to minimise the effect of torque. ...

Wet wing
A wet wing is an aerospace engineering technique where an aircraft's wing structure is sealed and used as a fuel tank. Wet wings are also called integral fuel tanks. By eliminating the need for fuel b...
V engine
A V engine, or Vee engine is a common configuration for an internal combustion engine. The cylinders and pistons are aligned, in two separate planes or 'banks', so that they appear to be in a "V" when...

Bow thruster
A bow thruster or stern thruster is a transversal propulsion device built into, or mounted to, either the bow or stern, of a ship or boat, to make it more manoeuvrable. Bow thrusters make docking easi...

Airscrew
An aircraft propeller or airscrew converts rotary motion from a piston engine, a turboprop or an electric motor, to provide propulsive force. Its pitch may be fixed or variable. Early aircraft propell...

Bypass duct
A bypass duct is an annular passage that allows some of a turbofan's airflow to bypass the engine core, or gas generator. If the turbofan is unmixed, the bypass duct will terminate at the bypass nozzl...
Drop tank
In aviation, a drop tank (external tank, wing tank, or belly tank) is used to describe auxiliary fuel tanks externally carried by aircraft. A drop tank is expendable and often jettisonable. External t...

Aircraft fuel system
An aircraft fuel system allows the crew to pump, manage, and deliver fuel to the propulsion system and Auxilary Power Unit (APU) of an aircraft. Fuel systems differ greatly due to different performanc...

Ferry tank
A ferry tank is an auxiliary fuel container that is usually temporarily attached to a motorized device which it feeds fuel to. A ferry tank allows the range or endurance of the vehicle or aircraft to...

S-duct
An S-duct (or serpentine inlet) is a type of jet engine intake duct, used in several types of trijet aircraft. In this configuration, the intake is in the upper rear center of the aircraft, above or b...

Contra-rotating propellers
Aircraft equipped with contra-rotating propellers, also referred to as CRP, coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston or turbopro...

Composite propeller
Composite propellers are made of an extremely strong, high-tech material. These propellers are produced using an injection molding process, which guarantees a high quality propeller every time. The co...
Diverterless supersonic inlet
A diverterless supersonic inlet (DSI) is a type of jet engine air intake used by some modern combat aircraft to control air flow into their engines. It consists of a "bump" and a forward-swept inlet c...

Thrust reversal
Thrust reversal, also called reverse thrust, is the temporary diversion of an aircraft engine's exhaust so that the exhaust produced is directed forward, rather than backwards. This acts against the f...

Ducted fan
A ducted fan is a propulsion arrangement whereby a mechanical fan, which is a type of propeller, is mounted within a cylindrical shroud or duct. The duct reduces losses in thrust from the tips of the ...

Turboprop
A turboprop engine is a turbine engine that drives an aircraft propeller. In contrast to a turbojet, the engine's exhaust gases do not contain enough energy to create significant thrust, since almost ...
