Abstract
A thrust reverser for a turbofan engine having a very high bypass ratio is disclosed having a plurality of baffles pivotally attached to a gas turbine engine housing so as to extend into a cold flow air stream emanating from the turbofan exit. The baffles are pivotally attached to the gas turbine engine housing and may be moved into extended, thrust reversing positions in which some of the baffles form a greater angle with the gas turbine engine housing than the remainder of the baffles. By moving the baffles located generally on opposite upper and lower portions of the gas turbine engine housing to the greater angles, the requisite thrust reversing force may be developed while at the same time minimizing the overall vertical dimension of the engine housing so as to provide the maximum amount of ground clearance for the turbofan engine. Secondary baffles are provided between the main baffles to close open spaces between the main baffles. Due to the orientation of the baffles in their extended, thrust reversing positions, the transverse configuration of the baffles is generally oval.
