Zusammenfassung:A thrust reverser for reversing a thrust of a turbofan engine of an aircraft. The reverser includes a pivot door, a cascade component, and an actuation system. The door is moveable between lowered and raised positions in which a side outlet is, respectively, covered and uncovered. The cascade includes turning vanes, and is moveable between forward and rearward positions in which the cascade is positioned, respectively, not over and over the side outlet. The actuation system deploys the reverser by simultaneously moving the door to the raised position and moving the cascade to the rearward position over the side outlet, and stows the reverser by simultaneously moving the cascade to the forward position and moving the door to the lowered position. When the door is raised and the cascade is over the side outlet, airflow through the side outlet is directed at least partially forward to provide reverse thrust.
