The ejector motive nozzle throat diameter (restrictiveness) is one of the key factors that affect ejector cycle COP.
Elbel and Hrnjak [1] were the first researchers to publish experimental results of introducing a variable two-phase ejector to a transcritical R744 system by installing a needle in the motive nozzle to control the motive nozzle throat diameter.
The flow rate for each test point was calculated by Equation 4, where 5 denotes the section upstream of the nozzle and 6 indicates the nozzle throat.
Motor upgrades from a shuttle booster include the addition of a fifth segment, a larger nozzle throat, and upgraded insulation and liner.
This would allow one of the most replaced items on fighter aircraft, the nozzle internal flap (the area between the exhaust nozzle throat and exit) to be designed based on thermal rather than mechanical constraints.

In the AVEN, all exhaust-flow turning is done in the nozzle's divergent (supersonic flow) section downstream from the nozzle throat, which prevents the feedback of any pressure fluctuations to the engine.
Likewise the flow rate for each test point was calculated by Equation 2, where 5 denotes the section upstream of the nozzle and 6 indicates the nozzle throat.
