Note the power may be coming from the shaft to drive the pistons as in a pump, or from the pistons to drive the shaft rotation as in an engine. A swashplate, also known as slant disk, is a mechanical engineering device used to translate the motion of a rotating shaft into reciprocating motion, or vice versa.
Linkages (silver) to the rotor blade In aeronautics , a swashplate is a mechanical device that translates input via the helicopter flight controls into motion of the main rotor blades . Because the main rotor blades are spinning, the swashplate is used to transmit three of the pilot's commands from the non-rotating fuselage to the rotating ...
The forward rotor is larger in diameter than the rear rotor, to avoid problems with eddies from the forward rotor tips. The rotors are powered by the engine shaft via an epicyclic gearbox. The rotors produce a large amount of heat. In late 2008, the RB3011 was considered a contender for the powerplant of the Irkut MS-21. Rolls-Royce felt it ...
Rolls-Royce LiftSystem. Instead of using separate lift engines, like the Yakovlev Yak-38, or rotating nozzles for engine bypass air, like the Harrier, the "LiftSystem" has a shaft-driven LiftFan, designed by Lockheed Martin and developed by Rolls-Royce, [3] and a thrust vectoring nozzle for the engine exhaust that provides lift and can also withstand afterburning temperatures in conventional ...
The higher the loading, the more power needed to maintain rotor speed. [3] A low disk loading is a direct indicator of high lift thrust efficiency. [4] Increasing the weight of a helicopter increases disk loading. For a given weight, a helicopter with shorter rotors will have higher disk loading, and will require more engine power to hover.
The rotor revolves around a fixed gear in a hula-hoop motion. The output shaft revolves at three times the speed of the rotor. One power pulse is delivered in one revolution of the output shaft. For comparison a single cylinder four-stroke piston engine delivers one power pulse for two rotations of the output shaft. The three operating chambers ...
