Title: Aircraft-propulsive combustion ducts,such as ramjet engines and turbojet afterburners
IPC: F23R3/20
Filed: 1964-09-03
Abstract: 1,019,050. Generating combustion products under pressure. GENERAL MOTORS CORPORATION. Sept. 3, 1964 [Sept. 25, 1963], No. 36087/64. Heading F1L. A combustion duct, for burning liquid fuel in combustion-supporting gas moving at high speed and for use in e.g. a gas turbine engine after burner or a ramjet engine, contains at least two annular, concentric, combined vaporizer fuel manifold and flame holder assemblies 27 and 28, Fig. 1, of different diameters, at least two fuel-injection manifold rings 24 and 25 located upstream of the assemblies and of different diameters therefrom, a further fuel-injection manifold ring 35 of greater diameter than the largest assembly and upstream thereof, and a flame-holder 29 co-operating with the further manifold ring. Four equally angularly spaced struts 14, each containing fuel passages 15 and 16, support the assemblies 27, 28, the manifold rings 24, 25 and flame holder 29 within the exhaust duct 10 of the jet propulsion engine, the afterburning section of which has an inner wall 70. For small thrust augmentation, fuel is admitted through fittings 19 and passages 16 to the assemblies 27 and 28, which are of similar construction, the former being shown in Fig. 3. From each passage 16, fuel flows through a passage 56 and an annular manifold 42, and is sprayed through orifice 43 into the combustion-supporting gas flowing through a ring 45 (see also Fig. 1), of U-shaped crosssection which embraces the manifold 42. Ring 45 becomes hot during operation, and the fuel is therefore vaporized, the resultant mixture passing through holes 51 into the flameholder which is formed by rings 48, 49, Fig. 1, welded to the ring 45. For increased thrust augmentation, fuel is admitted through fixtures 18 and passages 15 to the perforated manifold rings 24 and 25. Combustion of the resultant partly vaporized fuel spray is assured by the flames from assemblies 27 and 28. Still further thrust augmentation is obtained by supplying fuel to the perforated ring manifold 35, combustion of the partly vaporized fuel spray therefrom being stabilized by the downstream flameholder 29. The ring manifolds 24 and 25 and the annular manifolds 42 are each formed by four 90 degrees sectors, connected so as to allow expansion of each manifold. The U-shaped rings 45 and flameholder 29 are each mounted on the struts 14 so that they can expand radially relative thereto.
