Abstract

A thrust reverser is disclosed for a turbojet engine having a nacelle with a plurality of beams extending rearwardly from a rear portion of the nacelle on which are pivotally mounted thrust reverser baffles movable between forward thrust positions and reverse thrust positions. The thrust reverser baffles have forward edges, rear edges forming a portion of an exhaust nozzle when the baffles are in their forward thrust positions, outer baffle surfaces substantially flush with the outer surface of the nacelle when the baffles are in their forward thrust positions, and inner baffle surfaces forming a portion of a gas flow duct when the baffles are in their forward thrust positions, such that the exhaust nozzle has a width H measured in a direction parallel to the width of the beam h such that h is equal or greater than 0.6 H. In order to bias the thrust reverser baffles to remain in their forward thrust positions, the gases within the gas flow duct are prevented from acting on forward portions of the thrust reverser baffles when the baffles are in their forward thrust positions such that the resultant forces of the gases in the gas flow duct acting on the inner baffle surfaces when the…
