HyShot

HyShot is a research project of The University of Queensland, Australia Centre for Hypersonics, to demonstrate the possibility of supersonic combustion under flight conditions using two scramjet engines, one designed by The University of Queensland and one designed by QinetiQ (formerly the MOD's Defence Evaluation & Research Agency).

[3] Each combustion unit was launched on the nose of a Terrier-Orion Mk70 sounding rocket on a high ballistic trajectory, reaching altitudes of approximately 330 km.

Cold gas nitrogen attitude control thrusters were used to re-orient the payload for atmospheric reentry.

The experiments each lasted for some 5 seconds as the payload descended between approximately 35 and 23 kilometers altitude, when liquid hydrogen fuel was fed to the scramjet.

The payload landed about 400 km down range from the launch site, at which time its temperature was still expected to be about 300 degrees Celsius, which may be enough to cause a small brush fire and thereby make spotting and recovery easier even though a radio beacon was in the payload.
