Abstract

617,173. Gas turbines for jet propulsion. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., JOHNSTONE, A. P., and WALKER, D. N. Feb. 27, 1946, Nos. 6121 and 11922. Drawings to Specification. [Classes 110 (i) and 110 (iii)] In a gas turbine jet-propulsion plant part of the exhaust is evacuated up-stream of the propulsion jet during starting and low load running. This may be done by axially moving the final portion of the jet tube so as to leave a gap between it and the up-stream portion, or, by opening valves in auxiliary exhaust outlets. The control for this action may be coupled with the fuel control. With two turbines in series the auxiliary exhaust outlets may be between the turbines. With a long jet tube, the tube is fixed at its outlet end and the gap, which occurs at low temperatures, is closed by thermal expansion of the tube. The gap may be between plain ends, or telescoping ends with perforations as ports, or between flanges having interpenetrating annular rings which provide for thermal expansion after the gap is closed. According to the second Provisional Specification, the gap may be shut by means of the thermal expansion of the support. Also a similar gap in the delivery of an axial flow compressor may be used to prevent stalling at low-speeds. Reference has been directed by the Comptroller to Specification 623,108.
