Abstract: 957,918. Vertical lift jet engine nozzles. M.A.N.-TURBOMOTOREN. Sept. 8, 1961 [Oct. 6, 1960], No. 32402/61. Heading F1J. In a vertical take-off aircraft a vertical lift jet engine includes a gas discharge nozzle which is directed towards the ground and which incorporates an inner discharge pipe together with generally radially disposed tubes which connect the inner pipe with apertures in a surrounding. nozzle shell and so arranged that atmospheric air can be fed into the inner pipe to issue therefrom in the form of a core of relatively cold air within the hot gas jet issuing from the nozzle shell, so that on impingement of the jet on the ground, the core spreads out to form a relatively cold air screen between the surface and the hot gas jet. The nozzle shown in Fig. 3 has a converging portion 7, sonic velocity occurring at the nozzle outlet, and the gas stream expanding to sub-atmospheric pressure in the region indicated at 10. A hollow inner member 5 is disposed within the nozzle and comprises radial tube portions 6 into which air is drawn, and an outlet duct 8 which extends beyond the outlet end of the nozzle 7. In Fig. 4 the nozzle 71 is of the convergent divergent type, the low pressure region in the divergent portion being utilized to draw cooling air into the hollow member 51.
