Abstract
To control the separation of a hot gas ejection jet within a rocket engine nozzle, the device includes a jettisonable annular structure for placing around the outside wall of the nozzle at the gas cutlet section thereof, which structure defines a radial extension around the nozzle so that in the presence of an outlet jet coming from the nozzle, it creates a low pressure zone in the vicinity of the bottom face of the device, thereby displacing in the gas outlet direction jet separation from the interior wall of the nozzle.
