Abstract

612,796. Jet-propelled aircraft; boundary layer control. LYSHOLM, A. June 4, 1946, Nos. 16971 and 16972. Convention dates, June 4, 1945, and May 15, 1946. [Class 4] [Also in Group XXVI] In a jet-propelled aircraft, the outlet pipe of the gas turbine is associated with an ejector for removing the boundary layer from portions of the aircraft ahead of the ejector. As shown in Fig. 3, the gas turbine plant 6 is provided with a rearwardly and downwardly directed discharge opening 12 at the lower side of the fuselage, the rear portion of the discharge pipe being surrounded by a sleeve 11 forming the ejector and connected to a slot 18 in the wall of the fuselage. In the arrangement according to Fig. 4, the ejector is formed by casings 26, 29 surrounding and extending beyond the turbine casing 27. Boundary layer control slots such as 30, 31, 32 are provided in the air inlet ducts 24, and further slots 33, 34 are connected to suitable points on the surface of the aircraft. The Specification as open to inspection under Sect. 91 also describes, Fig. 4 (Cancelled), an aircraft with propeller 15 driven by a gas turbine 6, the discharge pipe 16 from the latter being directed rearwardly and downwardly, and terminating at the lower side of the fuselage. This subject-matter does not appear in the Specification as accepted.
