METHODS AND APPARATUS TO VARY REVERSETHRUST OF AIRCRAFT ENGINES

摘要

Methods and apparatus to vary reverse thrust of aircraft engines are disclosed. An example cascade apparatus disclosed herein includes a cascade frame (610) having a first end (620), a second end (622), and a fixed structure (618) extending between the first end and second end, where the cascade frame (610) defines a slot (626). A cascade (608) forms a reverse thrust flow path (606) and at least a portion of the cascade (608) is slidably coupled to the frame (610) via the slot (626). The cascade (608) slides relative the frame (610) between a first position to produce a first reverse thrust and a second position to produce a second reverse thrust, where the first reverse thrust is different than the second reverse thrust.
