Abstract: 804,391. Generating combustion products under pressure. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. May 22, 1956 [May 23, 1955], No. 15812/56. Class 51 (1). In a combustion apparatus of a jet propulsion unit comprising a gaseous type of flame stabilizing baffle, the cross-sectional area of the nozzle through which the auxiliary gas is injected is variable. In the ram jet unit shown in Figs. 1 and 5, a central body 2 is supported by radial arms 3 within the casing 1 and fuel is injected in an upstream direction from a ring manifold 4. Gaseous flame-stabilizing baffles are provided by means of ducts 6 which are formed at their outlets with lips 8, baffle-plates 9 being disposed adjacent the lips 8 so as to provide annular delivery orifices 7. The baffleplates 9 may be moved axially so as to vary the width of the delivery orifices. In a second embodiment a flat annular ring is associated with an annular manifold from which gas is discharged so as to provide two annular delivery orifices. The gaseous flame stabilizing baffle may be formed downstream of the fuel delivery means 25a as shown in Fig. 7. The movable plate 9 may be disposed on a rod 10, Fig. 8, the other end of the rod being formed as a piston 11 and mounted in a cylinder 12. Fluidpressure, for example fuel pressure, applied to the piston 11 causes the plate 9 to move against the pressure of spring 13 to an open position dependent on the rate of flow of fuel. A nut- and-boll; or rack-and-pinion type of actuation may alternatively be provided. In Fig. 11 the plate 9 is movable against the pressure of spring 13 by means of the pressure of the gas flowing in the duct 6, the gas flow being controlled by a throttle valve 19. In Fig. 15 the gas issues through a series of orifices 26 in the end of the duct 6, the areas of the orifices being varied by axial movement of a cylindrical sleeve 27. A pilot fuel injector and igniter may be disposed adjacent the gas discharge orifice; the pilot injector may project through the plate 9. The invention is also applicable to reheat combustion apparatus of gas turbine jet engines. Specifications 751,013 and 751,098 are referred to.

Abstract: 996,340. Induction ventilating units. JET-HEET Inc. April 19, 1962 [April 19, 1961], No. 15312/62. Heading F4V. In a ventilating unit of the air induction type in which high velocity air is supplied through an orifice 22, a convex air guide member 26 is located adjacent said orifice for forming the air into a film moving rapidly over the surface thereof. The guide member is secured to the rear lip 29 of the extended orifice 22 and its lower portion 27 has a greater curvature than the remainder of the member. Room air is induced to flow through inlet louvres 38 by the air film which then strikes an inclined baffle 90 at the top of the member 26 and mixes with the room air, the mixture being discharged through outlet louvres 42. The orifice 22 is formed in a nozzle assembly 25 which has smoothly curved side portions 83 (Fig. 2) and is supplied with hot or cold air through a tubular inlet 59. As shown, the size of the orifice may be varied by a slidable plate assembly 104 which has a polytetrafluoroethylene lining and is moved by a thermally responsive element 122 mounted in a manually adjustable knob assembly 94. During operation of the unit room air is induced to flow through the assembly 94 and over element 122 which thus responds to room temperature and moves the plate 104 through appropriate linkages (Figs. 6 and 7, not shown). At all positions of the plate 104 the ratio by weight of induced room air to supply air is maintained at or above 1 to 1. The casing 48 of the unit is lined with sound absorbent and thermally insulating material 52 and the inclined baffle 90 with moisture absorbent material 93. In modifications, the position of the plate 104 may be adjusted manually by a lever (Fig. 12, not shown) and the unit may be operated with the nozzle assembly at the top of the casing so that the high velocity air supply is discharged downwardly (Fig. 3a, not shown).
