<p>1,060,051. Jet lift aircraft. ROLLS-ROYCE Ltd. Jan. 3, 1966 [Jan. 11, 1965], No. 1258/65. Heading B7G. [Also in Division F1] A gas turbine engine comprises a jet pipe which terminates in a forward propulsion nozzle 15 and a downwardly-directed duct 16 connected to the jet pipe, whereby the engine can be utilized to provide vertical lift. A valve member 18 is provided whereby the gases may be directed either to provide forward thrust or vertical lift. The duct 16 terminates in a nozzle assembly 20 comprising a plurality of compartments 21, each in the form of pulse-jet units having inlet valve means which control the inflow of turbine exhaust gases, and fuel burners which supply fuel in a manner suitable for intermittent operation. When combustion occurs in each chamber, the inlet valves close and the combustion gases discharge through the open outlet. The nozzle assembly 20 may be provided in place of the normal forward propulsion nozzle.</p> |
