Repeatability among multi point calibration tests and non-liquefied flow were examined by statistical uncertainty assessment of measured Mach numbers. Enlargement of the Re number range, reduction of total temperature about 100 K and heat up time of the air heater were successfully attained. Represented statistical uncertainties of flow conditions clearly show that the NAL 1.27 m tunnel has better flow uniformity than that of the AEDC VKF-C tunnel., 資料番号: AA0047428003, レポート番号: JAXA-SP-03-003}, pages = {13--22}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {1.27m極超音速風洞の通風領域拡大:不確かさの表記と応用}, volume = {JAXA-SP-03-003}, year = {2004} }
