Abstract : The Hypersonic International Flight Research Experimentation (HIFiRE) program is a hypersonic flight test program executed by the Air Force Research Laboratory (AFRL) and Australian Defence Science and Technology Organisation (DSTO). HIFiRE flight five flew in April 2012. Principle goals of this flight were to measure hypersonic boundary-layer transition on a three-dimensional body. The second stage booster on this flight failed to ignite, so the experiment reached a maximum Mach number of only 3. Nevertheless, supersonic pressure and temperature data were obtained under laminar and turbulent flow, and flight systems were validated. HIFiRE-5 was the first HIFiRE flight to use both the Inertial Sciences Digital Miniature Attitude Reference System (DMARS-R) IMU and Ashtech DG14 Global Positioning System receiver. Results show that a tripped transition occurred on the test article leading edge, but the rest of the configuration showed no gross effects of tripping, with a transition pattern consistent with prior wind tunnel measurements and CFD.
