| PURPOSE: A VTOL(vertical takeoff or landing) aircraft by using a variable vane system is provided to control the yaw of a fuselage by offsetting torque from a propeller with plural variable yaw vanes and adjusting the angle of the vane, and to adjust pitch and rolling by using the drag with operating pitch and roll vanes. CONSTITUTION: A VTOL(vertical takeoff or landing) aircraft is composed of a propelling system having a propeller(1) and an engine(2); a torque control unit having a fixed yaw vane(3) and a variable yaw vane(4) installed in the lower part of the propeller to control yawing of the fuselage; a front pitch vane(5) and a rear pitch vane(6) controlling the direction of the fuselage pitch; a right roll vane(7) and a left roll vane(8) controlling rolling of the aircraft; and a duct(9) surrounding the propeller. Torque from the propeller system and yawing of the fuselage are controlled with the fixed yaw vane and the variable yaw vane. The size of the fuselage is reduced by eliminating a tail rotor from the yaw vane system, and breakage of the aircraft is minimized against collision. The structure is simplified, and maintenance is conveniently performed by using pitch and roll vanes. The performance of the propeller is improved with protecting the propeller by the duct. | ||||||
