Abstract

793,978. Generating combustion products under pressure. BAYARD, G. Nov. 25, 1955 [Nov. 29, 1954], No. 33890/55. Class 51 (1). [Also in Groups XXVI and XXVII] An engine starter (see Group XXVII) is powered by a gas turbine 6 driven by a mixture of hot gases and compressed air in the case of Fig. 1, and hot gases and steam in Fig. 2. In Fig. 1, compressed air from a bottle 1 or from a cooled compressor enters an expansion chamber 14 through a metering aperture 15 and passes through a valve 24 into a pipe 5 to rotate the turbine at slow speed. By means of a primer 17 powder in a container 16 is then ignited and fires a cartridge bag 18, the gases acting on a piston 23 to open a valve 25 so that air at high pressure passes into the pipe 5 and mixes with hot gases passing through apertures 22; the action of the valve closes the valve 24 through a trigger 29. When the powder in the bag 18 is all consumed, the valve 25 returns to its seat and the turbine stops. The valve 24 is reset by means of a handle 32. In Fig. 2, hot gases produced by firing a cartridge bag 36 pass through a port 40 into a chamber 39 so as to mix with a spray forced out of a nozzle 41 by the pressure of hot gases entering a water tank 33 through a pipe 38. The cartridge bag is such as to produce a reduced pressure initially.
