Abstract

796,400. Jet propelled aircraft. ROLLS-ROYCE, Ltd. Sept. 16, 1953 [Sept. 23, 1952], No. 23895/52. Class 4. A gas turbine engine, mounted in an aerofoil has an air intake, the area of which is adjustable firstly in accordance with the total temperature of the gas in the duct or of the external air and secondly with the flight Mach number. As shown, the duct upper and lower surfaces, 25 and 16 are adjustable, in accordance with temperature or Mach number by the rams 33, 32 respectively. The surfaces 13, 16 are pivoted at 12, 14 and make a sliding joint at 17. Links 23 connect 22 and 14. The surfaces 25 are pivoted at 29 and are connected to ram 33 by links 34. The controls of the two surfaces may be interconnected and the surfaces 16 may be apertured or made porous to permit removal of the boundary layer. Specification 795,050 is referred to.
