Abstract
The invention concerns a backblast gas structure for jet engine comprising a thrust reversal system with two downstream doors. The invention is characterized in that the two tilt-up doors articulated about axes (,) are mounted on two side beams (,) with free downstream edges (,) comprising protuberances (,). The door downstream edges (,) having median zones (,) forming an angle (A) with the lateral parts (,), such that when the doors are in retracted position in direct jet, the beam (,) edges (,) of the doors are found in the same plane (P,), thereby constituting a gas exhaust outlet which is planar and substantially circular. The invention aims at improving the power package performance in direct jet.
