Thrust reversing apparatus for a gas turbine engine.

摘要

A thrust reversing apparatus is arranged to divert gas flow through a cascade outlet (22) from a duct (13) defined between an engine centre body (10) and an engine cowling portion (15). The cowling portion (15) is movable to a rearward position (16) by an actuator (25, 26, 28) and doors (23) which are secured by hinges (40, 41) to the cowling portions (15) and to an output element (28) of the actuator are coupled by links (24) so as to move to positions (23A) which shut the duct (13) downstream of the outlet (22) as the latter is uncovered. Thrust from the actuator (25, 26, 28) is applied cirectly to both the cowling portion (15) and to the hinges (40, 41) of the doors (23).
