Abstract
885,271. Helicopters. ROLLS-ROYCE Ltd. Feb. 12, 1960. [Feb. 23, 1959], No. 6241/59. Class 4. [Also in Group XXIV] A rotary wing aircraft comprises a centrally disposed rotor (not shown) for effecting vertical movements of the aircraft, and two turbopropeller engines for providing forward thrust. Each turbo-propeller engine comprises high and low pressure compressors 10, high and low pressure turbines 12, 13, the low pressure turbine 13 driving a propeller 15 through reduction gearing and being connected by a clutch 27 (see Group XXIV) to an axial flow compressor 20. Compressed air from ducts 23 of the two compressors is employed in the production of the motive fluid used to drive the main rotor of the aircraft. As the result of such rotation the aircraft ascends, the pitch of the propellers 15 being differentially or collectively controlled to prevent yawing or pitching. When sufficient height has been gained the pitch of the propellers is increased until, with sufficient forward speed the clutches are disengaged. Specification 885,272 is referred to.
