Abstract
A thrust reverser is disclosed for an aircraft turbojet engine having a cowling with an inner surface forming an outer boundary of a gas flow duct, the cowling having at least one reverse thrust opening and a thrust reverser door pivotally attached to the cowling so as to move between a forward thrust position, wherein the thrust reverser door closes the at least one reverse thrust opening and a reverse thrust position, wherein a forward portion of the thrust reverser door moves outwardly from the cowing and a rear portion of the door moves inwardly into the gas flow duct so as to redirect a first portion of the gases flowing through the gas flow duct through the reverse thrust opening. The thrust reverser also includes a passageway bounded at least in part by the rear portion of the thrust reverser door located in the gas flow duct when the thrust reverser door is in the reverse thrust position, the passageway enabling a second portion of the gases flowing through the gas flow duct to pass to the rear of the thrust reverser door and to redirect this second portion of gases in an oblique direction relative to the gas flow duct to eliminate any forward thrust developed by the second portion of gases.
