The purpose of this test was to develop diagnostic techniques for the detection of hydrogen combustion in a hypersonic high temperature air stream. This was accomplished by ejecting hydrogen through sonic nozzles oriented normal to the airstream in the case of the flat plate model and at a 45-degree angle downstream in the case of the stepped flat plate model. The hydrogen gas was ejected into a high temperature airstream (T sub 0 4000 R) at Mach Number 4.14 to 4.24. The data is presented in three forms: (1) photographs; (2) graphical; and (3) oscillo graph traces.
