Abstract:
A tail sitter airplane will take off and land on its tail section, with its fuselage and nose pointed up. The airplane has a single driven propeller mounted to the nose section. Wings extend outward from the fuselage. Four airfoils locate in the tail section, two horizontal and two vertical. Each has a control surface. Four additional airfoils locate in a forward section, behind the propeller and in front of the wings. Two of the airfoils in the forward section are horizontal and two vertical. Movable control surfaces on these airfoils control the flight during takeoff and landing. The airfoils have chord lengths selected to remove the twist from the slip-stream from the propeller, thereby balancing the torque from the propeller.
