Abstract: 810,189. Jet propulsion plant. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. July 17, 1956 [July 22, 1955], No. 21357/55. Class 110 (3). [Also in Group XXIX] A jet propulsion nozzle has retaining walls defining a flow path of convergent-divergent form comprising a first nozzle portion which converges to a nozzle throat, a wholly divergent outlet nozzle portion, the upstream edge of the outlet portion lying near but outwardly stepped from the downstream edge of the first portion providing therebetween an annular fenestration through which fluid can enter the flow path and means operable on occasion to prevent fluid flow through the fenestration. The expression " outwardly stepped " is stated to mean that the downstream edge of the first nozzle portion and the upstream edge of the outlet portion lie on a conical surface which diverges rearwardly, the divergence of the surface being greater than the divergence of the outlet portion adjacent the upstream edge. The propelling nozzle shown, Fig. 2, comprises an entry portion 6 and an outlet portion 7. The internal diameter of the inlet end 8 of the portion 7 is larger than that of the adjacent convergent end 9 of the portion 6 and is spaced downstream from it to form a fenestration 10 which lies in a conical surface the divergence of which is greater than that of the outlet portion. The wall portions 6, 7 are connected by side beams 11 and carry flanges 12, 13 supporting guide rods 14. The rods 14 support an axially slidable closure ring 20 which has an internal conical seating surface arranged in one position to engage corresponding seating surfaces on the flanges 15, 16 attached to the wall portions 6, 7. The flange 16 is mounted on the portion 7 by bellows 17 which may yield axially when the ring 20 is seated to compensate for differential expansion. The ring 20 is actuated by three hydraulic jacks controlled by a servomotor 25 and a pressure-responsive device 26 responsive to the pressures at the inlet and outlet of the nozzle. In a modification the device 26 may be replaced by a Machmeter. In another modification, the portions 6, 7 are connected by a cylindrical casing having ports which may be opened or closed by an axially or circumferentially moving closure member. Means may also be provided as shown, Fig. 9, to vary also the area of the throat of the nozzle. A wall 67 is attached to the flanges 12, 15 to form a chamber 65 to which pressurized fluid is supplied through conduits 69 controlled by valves 70. A slot or series of apertures connects the chamber 65 with the interior of the nozzle. In another modification a variable area nozzle of the caliper type is embodied in the throat of the nozzle. The entry and outlet portions need not be of purely conical form, e.g. may be of convex inward form in the axial direction.
