Abstract

1386232 Thrust reverser; propelling ships SHORT BROS & HARLAND Ltd 27 March 1972 [31 March 1971] 8283/71 Headings B7G and B7V A fluid propulsion system comprises a rigid inner wall and an outer wall defining a flow passage 29, the outer wall comprising upstream and downstream portions 27, 30, the downstream portion being movable in an axial direction only between a position, Fig. 3 (not shown), in which it abuts the upstream portion and a thrust reversal position, Fig. 4, in which it is axially spaced from the upstream portion to leave an annular gap and in which it closes the flow passage to divert fluid flow through the gap. The flow passage 29 may be a by-pass duct between a cowling and an engine casing 25. The downstream portion 30 is formed with an upstream wall 32 mating with the downstream end of cowling portion 27 and having an inwardly extending wall 33 which in the thrust reversal position abuts a portion of increased diameter of the casing 25. The portion 30 carries jet deflector apparatus which is received in an annular cavity 40 in the cowling 27 in the cruise position and which comprises four arcuate assemblies 36 of circumferentially extending vanes 38 carried by axial beams 37 extending between the downstream portion 30 and an annulus 90; the two upper assemblies 36 also include axially extending vanes 39 which serve to direct reversed air away from the aircraft structure. The downstream portion 30 is moved by hydraulic actuators 44 whose rods 46 are connected thereto and whose cylinders 45 are connected to the cowling and have flanges 47 sliding in channels 50 in the beams 37. Alternatively, Figs. 6-10 (not shown), the flow passage may be a duct (109) between the wall of a nozzle (111) and a centrebody (110). In this embodiment the deflector apparatus is formed as a single annular assembly (121) and the downstream portion is moved by means of screw jacks (131). The system may be an air jet propulsion engine for an aircraft or surface vehicle, or may use liquid as the propulsive medium in the case of surface or under-water vehicles.
