Abstract

1,273,537. Jet propulsion plant. H. A. KERSHAW. May 6, 1969 [May 28, 1968], No.25433/68. Heading F1J. The invention relates to a ducted fan type jet engine wherein the fan is driven by a gas turbine engine which comprises a gas compressor in which the working gas is cooled during compression the gas then being heated during expansion and used to drive a turbine which drives the fan, the exhaust gas from the turbine being returned to the gas compressor. In the embodiment shown the ducted fan is indicated at 1 and is driven by a gas turbine engine 2 of the jet compressor type. The compressor comprises an entraining chamber 9a in which a plurality of nozzles 18 are disposed which act to entrain air and direct it through venturi tubes 10a, the air so pressurized passing to inlet manifold 12 and thence to turbine 11 which is connected to drive the ducted fan 1. The air discharging from the turbine passes to exhaust chamber 8 and then passes back through ducts 13, 14 to the entraining chamber 9a to repeat the cycle. A portion of air discharging from each venturi tube 10a is tapped off through duct 17 and passes under control of valve 19 to the ejector nozzle 18 so acting to entrain air in chamber 9a. Each venturi tube 10a is enclosed in a casing 16 and has a heating unit 15 such as an electric heater associated therewith. Alternatively the air in the venturi tubes may be heated by passing electric current through the tubes. The heaters may be used only at starting, it is stated. Air from the ducted fan 1 passes to a nozzle assembly 3, 4, 5 from which air may be directly either rearwardly through nozzle 4 for forward thrust or downwardly through nozzle 5 for vertical lift, air being deflected towards nozzle 5 by control jets 3a supplied with air under pressure from air compressor 6. A deflecting lip 3a is also provided. The air discharging through nozzle 4 may be heated by means of electrodes 22 mounted on trunnions 23, the electrodes discharging electricity from their rearward ends through insulated ducts 24. Many alternative arrangements are described.
