Free-flying model testing is a common technique used in hypersonic impulse test facilities to measure forces over scaled models of hypersonic vehicles. While this technique is widespread in low enthalpy facilities and reflected shock tunnel facilities where test times are generally of the order of milliseconds or longer, it has largely been unexamined in very high enthalpy hypersonic impulse facilities such as expansion tubes due to their much shorter test times of generally much less than a millisecond. Recent work in UQ’s X2 expansion tube has aimed to change that by beginning free-flying model testing and validation in the facility. This paper will summarise current free-flying model testing in UQ’s X2 facility while also discussing new supporting techniques which are being developed, such as an off-axis parabolic schlieren system for model illumination and a pneumatically operated model release system.
