Title:
CONTROL SYSTEM FOR VERTICAL TAKE OFF AND LAND (VTOL) AIRCRAFT
Document Type and Number:
WIPO Patent Application WO2003068597
Kind Code:
A3
Abstract:
A vertical take off and land (VTOL) jet aircraft (100) may have a jet engine mounted in a forwardportion of the aircraft. A thrust deflection assembly may be provided rearward of the jet engine,and include a cascade (206) and control box (208) for deflecting thrust during vertical flight of the aircraft.By manipulating the cascade (206) and control box (208), the roll, yaw and pitch of the aircraft duringvertical flight may be controlled. In addition, ailerons, a rudder and elevators may be providedfor controlling roll, yaw and pitch during forward flight. A pilot control input apparatus (102) is provided, which receives pilot input regarding desired roll, yaw and pitch of the aircraft.The pilot control input is operatively associated with a control mixer (108), which controls the control box, ailerons, rudder and elevators in accordance with the desired roll, yaw and pitch of the aircraft. As a result, the pilot uses the same control input apparatus for vertical and forward flight.
