Abstract
Methods and apparatus to vary reverse thrust of aircraft engines are disclosed. An example cascade apparatus disclosed herein includes a cascade frame having a first end, a second end, and a fixed structure extending between the first end and second end, where the cascade frame defines a slot. A cascade forms a reverse thrust flow path and at least a portion of the cascade is slidably coupled to the frame via the slot. The cascade slides relative the frame 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.
