Abstract
The supersonic ejector utilized for cooling includes a cooling extension axially extending the discharge slot from the throat of the primary stream and is contoured to accelerate primary stream, to direct the primary stream to flow parallel to the secondary stream and match the static pressures of both streams and to ensure that the expansion shocks are upstream of the discharge slot. This supersonic ejector is utilized in one instance for cooling purposes in a two-dimensional vectoring nozzle of a gas turbine engine powering aircraft.
