Vertical takeoff and landing aircraft

Abstract:

There is provided a vertical takeoff and landing aircraft (VTOL), having a main propulsion unit (GT engine) with high-pressure and low-pressure turbine shafts installed along a longitudinal axis of a frame to be rotated by pressurized gas jetted on combustion of an air-fuel mixture to produce propulsion force in a longitudinal direction of the frame, high-pressure side and low-pressure side motor generators coaxially attached to the high-pressure and low-pressure turbine shaft, four fans installed on the frame to be rotatable around axes parallel to a vertical axis of the frame, four propulsion units individually connected to the fans to rotate them and generate lift force in a vertical direction of the frame, and a controller. The controller control operation of the main propulsion unit, motor generators and sub propulsion units to obtain propulsion forces in the longitudinal direction and in the vertical direction of the frame.
