An arc-heated wind tunnel test was conducted to confirm the measurement method of stagnation pressure on JAXA lightweight ablator in JAXA 750 kW Arc-heated Wind Tunnel. In this test we confirmed pressure measurement system installed on the small size re-entry capsule will work and this will not cause ablator breaks. And we found two problems for more accurate measurement: 1) the influences of ablator recession around pressure port and 2) ablator-gas on the measurement.
