Abstract

892,289. Controlling boundary layer. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Feb. 3, 1959 [Feb. 13, 1958], No. 4738/58, Class 4. [Also in Group XXVI] A variable area intake for a ram jet engine formed by four pair of plates 8, 10 hinged together at 12, one of the plates 8 being hinged is fixed structure at 9 and the other plate 10 being hinged to an axially movable support 11, has a slot 20 at each hinge to bleed off the boundary layer of air from each pair of plates.
