Abstract

670,296. Elastic-fluid turbines. ROLLSROYCE, Ltd. May 25, 1950. [June 1, 1949] No. 14765/49. Class 110(iii). [Also in Group XXXIII] In a gas turbine exhaust assembly comprising an outer wall 10 with a substantially conical fairing 11 supported therein to define an annular duct 12 which constrains the exhaust gases to flow towards the longitudinal axis of the turbine, means are provided for removing boundary layer gases from the surface of the fairing. The fairing has a convex portion 11a and a concave portion 11c which has an outer skin 11b to form a passage 15 through which the boundary layer is drawn off. The skin 11b terminates in a nozzle 17 downstream of the apex of the skin 11c. In a modification the apex of the skin 11c is formed as an ejector which is fed with air from the compressor and the skin 11b constitutes a shroud.
