초록

Systems and methods for altering airflow to gas turbine engines are provided. In this regard, a representative system includes a gas turbine engine inlet having a slat, the slat being movable between a retracted position and an extended position. In the extended position, the slat increases an effective diameter of the inlet compared to the diameter of the inlet when in the retracted position.

청구항

1. A system for altering inlet airflow to a gas turbine engine comprising: a gas turbine engine inlet having a top side and a bottom side meeting at a leading edge thereof, and a slat, the slat being movable between a retracted position and an extended position;in the extended position, the slat increasing an effective diameter of the inlet compared to the diameter of the inlet when in the retracted position; and in the retracted position, said slat has an aft inner surface that conforms along its entire length to and rests atop a forward surface of the ...
