ABSTRACT:
An engine and lift unit for rotary wing aircraft together with means for balancing of the rotational torque of the said wings is shown. The rotational torque is balanced by a blower propeller, disposed horizontally below the rotor, inside an enclosure including a vertical duct surrounding the blower propeller and whose lower open end exits under the fuselage of the aircraft. A horizontal duct opens into an intermediate zone of the vertical duct and exits out the rear of the aircraft. An adjustable shutter assembly is disposed in the junction of the two ducts allowing the creation of two adjustable air flows, one directed vertically downwards and the other directed towards the rear of the aircraft. The aircraft also has fixed wings, flaps, rudders and controls so the pilot can operate the aircraft in flight.
