A high wing, twin jet gyrodyne having air jet reaction, contrarotating rotors powered with bypass air from twin turbofan engines. Tail pipes from the turbofan engines are disposed parallel to and at opposite sides of a longitudinal duct for discharging bypass air rearwardly. Control valve means can control supply of bypass air selectively to the hollow rotor mast for driving the rotors and to the longitudinal air discharge duct. The aft portions of the tail pipes and of the air discharge duct are connected by a horizontal stabilizer and rudders are locat...
A gyrodyne comprising a hollow mast, contrarotating rotors carried by said hollow mast, turbofan engine means carried by the gyrodyne, air discharge means carried by the blades of said contrarotating rotors for discharging transversely thereof air received from said hollow mast to effect reaction rotation of said rotors, duct means connecting said turbofan engine means and said hollow mast for receiving bypass air from said hollow turbofan engine means and conveying it to said hollow mast for flow therethrough to the rotor blades, and control means for v...
