Abstract

The flow during transient startup and shutdown in all rocket engines operated on sea level under ambient conditions will separate inside the supersonic part of the nozzle. A separated nozzle flow is circumferential asymmetric distributed and induces high side loads. DLR carried out a cold flow subscale test campaign to study devices that can reduce the side loads during transient operation of a thrust optimised parabolic nozzle. A detailed parametrical study was performed and experimental data demonstrate the potential of the device to reduce the side loads.
