Experimental Studies of a Ludwieg Tube High Reynolds Number Transonic Tunnel

Abstract

Significant justification for a much higher Reynolds number ground test capability in the transonic regime has developed in the past few years. An extensive experimental investigation of a high Reynolds number transonic wind tunnel employing a Ludwieg tube air storage system has been undertaken at the Arnold Engineering Development Center to assess the utility of such a device. The transonic starting process and starting time of this impulse facility have been carefully evaluated, and the spatial and timewise quality of the test section flow has been analyzed. Results from studies of the aerodynamic flow response time at transonic speeds and measurement of the pressure distribution and forces on selected models are presented.
