Kurzfassung
An experimental study with respect to the influence of temperature changes on the interaction of a SERN nozzle flow with the external flow around a nozzle model has been performed in the hypersonic wind tunnel H2K. The static pressure along the expansion ramp and the nozzle flap was measured at varying total temperatures of the nozzle flow between 300 K and 1000 K. Additional information about the flow was gained by Schlieren optics. It was found that the axial thrust was increased by up to 1.5 per cent with increasing air temperature. Considering the impact of the nozzle thrust on the net thrust of airbreathing engines at hypersonic speeds, this demonstrates the importance of simulating the "hot" nozzle flow for the investigation of interacting nozzle flow fields.
