ejector nozzle

Advantages of the ejector nozzle are relative simplicity and reliability.

Although more complex than the ejector nozzle, it has significantly higher performance and smoother airflow.

The nacelle airflow from the intake controlled the expansion of the hot engine exhaust in the ejector nozzle.

The simpler of the two is the ejector nozzle, which creates an effective nozzle through a secondary airflow and spring-loaded petals.

The propulsion system consisted of the intake, engine, nacelle or secondary airflow and ejector nozzle(propelling nozzle).

The rear engine exhaust was closed and the gases redirected through ducts to ejector nozzles in the wings and canards for vertical lift.

The ejector nozzle, together with the engine variable nozzle, performed the reverse function of the inlet accelerating the turbine exhaust from about Mach 0.4 back up to Mach 3.
