Abstract
Gas turbine engine power plants sometimes are provided with thrust reversing equipment, the outlet of which is close to the power plant air intake. Such arrangements create re-ingestion problems. There is described herein an apparatus which either maintains the upstream portion of reversed flow in a given position with respect to the plane of the air intake or alternatively destroys the reversed flow entirely.
Claims4
A gas turbine engine power plant including a thrust reverser capable of directing a reversed flow of air along an exterior surface of a cowl of the power plant whereby to effect reverse thrust and thereby generate a mobile high pressure area on the cowl external surface, at the interface of forward flowing reversed airflow and ambient air, mobile high pressure area sensing means and mobile high pressure area stabilising means whereby in operation, said sensing means senses the pressure change which occurs as the mobile high pressure area reaches it and actuates the mobile high pressure area stabilising means so as to stabilise the position of the mobile high pressure area with respect to a point on said cowl.
