Patent GB-2238996-A (GB)
Title: Compound helicopters
Inventor: HUMPHERSON DAVID VINCENT
IPC: B64C27/82
Filed: 1990-12-05
Abstract: A lift rotor (13) providing a major portion of lift for vertical take-off/landing, hover and slow speed flight of a compound helicopter is driven through a gearbox (18) by a gas turbine engine (16) having a variable area final exhaust nozzle (33). The engine also provides power for driving a fan (21) to produce a flow of air internally of a tail boom structure (12). Air is vented through slots (23) in the tail boom to control circulation of lift rotor downwash air over the tail boom thereby producing a lateral force for counteracting the effect of lift rotor torque. Air is also vented from the tail boom through air outlet ports (24) to produce lateral forces for yaw control. In high speed flight the major portion of lift is provided by a fixed wing (15). The exhaust nozzle is set such that substantially all of the engine power is used for propulsion and the lift rotor and fan are off-loaded. For high speed flight yaw control is provided by a fin (27) and rudder (28) mounted on the tail boom. This maximises use of engine power for propulsion and provides a low drag tail boom allowing higher forward speeds to be obtained. <IMAGE>
