In UK patent 2261203 Keith Ralbert Sherriff describes a VTOL light aircraft. Two variable pitch rotors are housed one behind the other within the fuselage to draw air through front intakes and through intake louvres in the top of the fuselage, and expel it through controllable flaps in the bottom of the fuselage and/or through a rear exhaust nozzle. The rotors are inclined to the fuselage horizontal plane and rotate in opposite directions. In the hover, yaw control is by vanes in the exhaust nozzle and lateral control by a weight movable spanwise within the wing, while differential pitch control of the rotors is used for pitch control of the aircraft. The pilot lies in a prone position.
