Abstract

908,307. Jet propulsion plant. BRISTOL SIDDELEY ENGINES Ltd. July 25, 1961 [July 25, 1960], No. 25817/60. Class 110 (3). [Also in Group XXXIII] An aircraft propulsion power plant comprises a gas turbine engine 1, a jet pipe 20 connected to receive the turbine effluent and having a straight end part including a reheat combustor 47 and a jet nozzle 51, a duct branching from the jet pipe upstream of the reheat combustor, and a valve system upstream of the reheat combustor for distributing the turbine effluent between nozzle 51 and the branch duct. In the Figure, the branch duct leads to a nozzle 30, but may instead feed a free turbine driving a lifting fan. The nozzle 51 is of variable area, and comprises a ring of overlapping flaps 52 pivoted at 53 to a convergent end part of the jet pipe and carrying cam follower rollers 54 held in engagement with a frusto-conical cam surface 55 on sleeve 56 by the pressure of the gas stream. The sleeve is slidable by jacks 57 to vary the outlet area defined by the flaps. A fixed divergent section 58 is operative when the flaps are expanded to the diameter of its entry, as in Specification 820,059. Specifications 825,547 and 826,963 also are referred to.
