Kurzfassung
An experimental study was conducted testing Dual-bell nozzles in various conditions at DLR’s cold gas test stand. The stability of the nozzle flow has been verified by measuring the pressure ratio values by flow transition and retransition, to ensure a hysteresis between the two operation modes. The transition duration and the velocity of the transition front in the nozzle extension were calculated using pressure measurement and Schlieren optics to demonstrate the feasibility of the Dual-Bell concept.
