| Popis: | In the present study, CFD study was performed for 4 bladed rotor in BVI condition in order to validate its predictable ability. The computation was chosen for the corresponding BVI test case which has been performed in the previous wind tunnel test that has been conducted under collaborative research with NAL and MHI in May, 2002. The wind tunnel test was performed with free stream velocity and the rotor angle of attack being the primary parameters. The blade pitch was cyclically controlled to achieve desired thrust amount. As output from the test, measured are rotor six-component force, near leading edge pressure data and sound pressure history at fixed observation. Likewise, CFD computation was performed and was validated against these corresponding data. 資料番号: AA0047427002 レポート番号: JAXA-SP-03-002 |
