Alleviation of such acoustic damage is a key to a reliable and competitive rocket system. JAXA, planning an advanced solid rocket system, started design of the launch-pad with less acoustic impact. Semi-empirical model such as NASA-SP-8072 and numerical model by computational aero-acoustics (CAA) have been introduced to establish better design guideline. However, more experimental data in static firing tests should be obtained for validation and improvement of both models. Meanwhile, we had an opportunity of testing three solid rocket motors; NAL735, M24 and KM-V1 since December in 2007. This paper outlines acoustic measurement carried out in the ground firing tests of these motors., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064672026, レポート番号: JAXA-SP-09-011}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {地上燃焼試験における固体ロケットモータの音響計測}, volume = {JAXA-SP-09-011}, year = {2010} }
