  2. Coaxial-rotor aircraft - Wikipedia

    en.wikipedia.org/wiki/Coaxial-rotor_aircraft

    A coaxial-rotor aircraft is an aircraft whose rotors are mounted one above the other on concentric shafts, with the same axis of rotation, but turning in opposite directions (contra-rotating). This rotor configuration is a feature of helicopters produced by the Russian Kamov helicopter design bureau .

  3. Contra-rotating - Wikipedia

    en.wikipedia.org/wiki/Contra-rotating

    A Soviet Ka-32 helicopter with coaxial contra-rotating rotors, in 1989. 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.

  4. Contra-rotating propellers - Wikipedia

    en.wikipedia.org/wiki/Contra-rotating_propellers

    Contra-rotating propellers Contra-rotating propellers on the Rolls-Royce Griffon-powered P-51XR Mustang Precious Metal at the 2014 Reno Air Races. Aircraft equipped with contra-rotating propellers (CRP) [1] coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston engine or turboprop engine to drive a pair of coaxial propellers in contra ...

  5. Tandem-rotor aircraft - Wikipedia

    en.wikipedia.org/wiki/Tandem-rotor_aircraft

    Tandem-rotor helicopters, however, use counter-rotating rotors, with each cancelling out the other's torque. Therefore, all of the power from the engines can be used for lift, whereas a single-rotor helicopter uses some of the engine power to counter the torque. [1] An alternative is to mount two rotors in a coaxial configuration.

  6. Gyrodyne - Wikipedia

    en.wikipedia.org/wiki/Gyrodyne

    a rotary wing aircraft intermediate in type, hereinafter referred to as "gyrodyne", between a rotaplane (with the rotor free for autorotation and an upward total axial flow through the rotor disc), on the one hand, and a pure helicopter (with the rotor driven, and a downward total axial flow through the rotor disc), on the other hand, that is ...

  7. Breguet G.111 - Wikipedia

    en.wikipedia.org/wiki/Breguet_G.111

    Though a much larger aircraft, the G.11E used the same coaxial, three blade twin rotor layout as on the Gyroplane Laboratoire. It was initially powered by a fan cooled 179 kW (240 hp) Potez 9E nine cylinder radial engine mounted amidships, under the concentric rotor shafts. There was 6.5:1 speed reduction gearing between the engine and the ...

  8. Engine configuration - Wikipedia

    en.wikipedia.org/wiki/Engine_configuration

    1919 Napier Lion II aircraft engine with three cylinder banks. Piston engines are usually designed with the cylinders in lines parallel to the crankshaft. It is called a straight engine (or 'inline engine') when the cylinders are arranged in a single line. Where the cylinders are arranged in two or more lines (such as in V engines or flat ...

  9. Rotary engine - Wikipedia

    en.wikipedia.org/wiki/Rotary_engine

    A rotary engine is essentially a standard Otto cycle engine, with cylinders arranged radially around a central crankshaft just like a conventional radial engine, but instead of having a fixed cylinder block with rotating crankshaft, the crankshaft remains stationary and the entire cylinder block rotates around it.
