Title:
ANTI-TORQUE AND YAW-CONTROL SYSTEM FOR A ROTARY-WING AIRCRAFT
Document Type and Number:
WIPO Patent Application WO2002087967
Kind Code:
A3
Abstract:
A rotary-wing aircraft (12) comprises a main rotor (14), a tail boom (22) extending through an area of downwash (26) from the main rotor, and first and second linear nozzles (33, 35) fixedly coupled to the tail boom. The first nozzle is adapted to discharge a sheet (43) of fluid in a direction substantially tangential to an outer surface (22a) of the tail boom to divert the rotor downwash and thereby produce a force that counteracts the biasing torque of the main rotor. The rotary-wing aircraft further comprises a yaw-control member (37) movably coupled to the tail boom. The second nozzle is adapted to discharge a sheet of fluid in a direction substantially tangential to an outer surface of the yaw-control member to further divert the rotor downwash and thereby increase the force that counters the main-rotor torque.
