Abstract

940,832. Thrust reversers on aircraft. ROLLS-ROYCE Ltd. Feb. 28, 1962 [March 21, 1961], No. 10350/61. Heading B7G. [Also in Division F1] In a by-pass jet propulsion engine a by-pass duct 20, Fig. 1, communicates with the exhaust gas duet 18 through mixer shoots 21 provided with valves 25 which close either the by-pass duct or the mixer shoots in order to divert bypass air into the exhaust gas duct 18 or to allow it to pass downstream through the bypass duct, fuel injection means being arranged upstream of the mixer shoots which act as flame stabilizers during re-heat combustion, see Division F1. Valve members 23 are movable from the position shown in Fig. 1 to a position preventing gas flow to variable-area nozzle 19, and allowing flow to vanes 24 to give reverse thrust.
