초록 ▼

A thrust reverser for use with turbo-fan aircraftt engines; in particular engines mounted on an aircraft fuselage. Four radially spaced openings around the engine each is closed by a stowed door. An actuator is provided to move each door to a deployed position extending through the opening, near the aft end of the opening. The aft end of each door extends into the tailpipe and directs air flow out through the opening, where the forward end of the door further directs the flow in an outwardly and forwardly direction. Doors adjacent to the aircraft fuselage are shaped to guide reverse airflow away from direct impingement on the fuselage. Deployable strakes are mounted on doors adjacent to the fuselage. The strakes are typically spring biased toward a stowed position flat against the inside of the door and are moved to a deployed position by aerodynamic forces when the doors are deployed. In the deployed position, they are located so as to deflect air flow away from the fuselage or other structures.
