This paper is concerned with an information of detailed performance of a small size high-enthalpy supersonic wind tunnel constructed for the purpose of the experimental study of ablation and also with the results of an experimental investigation of stagnation ablation carried out by use of models made of teflon. It is shown that the flow in the test chamber is uniform with respect to stagnation pressure and temperature within a circular cross section of 40 mm diameter at the stagnation temperature below 1200℃, thus indicating that the wind tunnel is adequate and satisfactory for making experimental investigation concerning ablation. Measurement of ablation rate at stagnation point and observation of detached shock wave are carried out by use of hemisphere-cylinder models made of teflon and the results are compared with existing theory. Agreement between theory and experiment is fairly good.
