Catalytic combustion is a candidate for an apparatus to stabilize and promote combustion for a Scramjet engine that is a strong candidate for thrusters of space planes and supersonic airplane in the next generation. However, the mechanism of catalytic combustion in the supersonic flow has hardly been clarified because there are little cases of the research on catalytic combustion in the supersonic flow, especially at the unsteady Field. In this research, we tried to measure catalytic heat release rate at the unsteady flow behind a shock wave using Ni or Pt prove and a shock tube. The temperatures of Ni or Pt wire are controlled by the electric circuits. When a shock wave reaches Ni or Pt hot wire probe, the supplied power by the circuit rise. The power to Pt wire is smaller than that to Ni wire because catalytic reaction occurs on a surface of Pt wire.
