Waseda University, International Conference Center), Tokyo Japan, Unsteady Pressure-Sensitive Paint (PSP) measurement of a rocket fairing model was conducted at the JAXA 2m x 2m Transonic Wind Tunnel as a part of the campaign to investigate the steady and unsteady flow field around it and to obtain the CFD validation data. Anodized-aluminum PSP was coated on the model surface, and it was illuminated using a high-power blue laser diode. AA-PSP luminescence was measured by a high-speed camera, whose frame rate was 5kfps. The high-speed camera images were calculated to the Cp data using in-situ PSP calibration. Unsteady PSP data captured unsteady pressure data on the rocket fairing model as time-series Cp images. The unsteady phenomena on the model were significantly varied according to the Mach number and the angle of attack. Frequency analysis was also applied to the time-series Cp data. Unsteady pressure distribution was clearly investigated from the power spectrum results., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0065207034, レポート番号: JAXA-SP-11-015}, pages = {195--200}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {ロケットフェアリング模型の非定常PSP計測}, volume = {JAXA-SP-11-015}, year = {2012} }
