ABSTRACT:
A method and apparatus are disclosed for limiting ingestion of debris into the inlet of a gas turbine engine. The invention includes providing first means in communication with a source of fluid under pressure for introducing at least one jet of fluid at a point aft of the leading edge of a nacelle associated with the engine inlet. The first means are adapted to discharge the fluid jet away from the leading edge and in the aft direction to establish a low pressure region aft of the leading edge and in sufficient proximity to a second vortex formation region so as to draw airflows from the second region into the low pressure region and away from the engine inlet.
