Abstract

862,032. V.T.O. aircraft with boundary layer control. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Sept. 21, 1959 [Oct. 3, 1958], No. 31610/58. Class 4. [Also in Group XXVI] An aircraft has a fan arranged to draw in air and discharge it as a downwardly directed stream for imparting upthrust to the aircraft, a turbine in driving connection with the fan, a boundary layer suction opening in the aircraft outer surface, and an air compressor which can be connected either to supply air to the turbine to drive the fan or to draw in air through the suction opening. The aircraft comprises a fuselage 1, wings 2, tail unit 3 and a pair of jet propulsion engines mounted in a nacelle 4 on each side of the rear end of the fuselage. A plurality of lifting fans 6 are mounted in the fuselage and a fan 7 of similar construction is mounted at each wing tip to provide lateral control of the aircraft. Each wing is formed with spanwise-extending suction slots 8 and a number of porous sections 9 extending over a considerable part of the wing, such that when suction is applied to the slots 8 and sections 9 laminar flow in the boundary layer over substantially the whole of the surface of the wing is maintained. Each fan 6, 7 comprises an axial flow rotor housed in a vertically arranged duct surrounded by an annular volute housing a turbine comprising blades mounted on the extremities of the blades of the rotor. Guide vanes are provided and the blades and vanes may be angularly adjustable and the inlet and outlet apertures of the ducts may be closed with shutters or the like when the fans are not in use. Suction openings may be provided additionally at selected positions on the fuselage and tailplane. Each jet propulsion engine comprises a compressor section 21, combustion system 22 and turbine section including a rotor 23 driving the compressor through shaft 24 and a rotor 27, independent of rotor 23, which drives an auxiliary compressor 29 through a shaft 28. Compressor 29 has one inlet 40 connected to atmosphere or closed by a valve 42 and another inlet 36 connected or closed, by a valve 38, to a trunking system associated with the boundary layer suction slots. The outlet from compressor 29 may be connected by pipe 37 and valve 39 to the turbines of the lifting fans or by pipe 41 and valve 43 to atmosphere, the outlet from pipe 41 providing a supplementary propulsive jet. In operation, and for vertical take-off, valves 42 and 39 are open and valves 38 and 43 are closed so that air is delivered from compressor 29 to the turbines of the lifting fans and during forward flight, with the lifting fans inoperative, valves 42 and 39 are closed and valves 38 and 43 opened to apply suction at the slots 8 and sections 9. Specification 811,840 is referred to.
