Abstract
During the transient start-up and shut-down of rocket engines, the supersonic flow inside the divergent section of the rocket nozzle separates, causing undesired side loads. An experimental test campaign was conducted to study the effect of chevrons on the flow separation in rocket nozzles, and thus a potential side load reduction. Positive results were obtained and are presented here.
