ADN, MMAN and AA were mixed at 40, 40 and 20 wt% by mass (AMA442). The combustion tests were also carried out on mixtures of ADN/MMAN and ADN/AA prepared to the same mixing ratio as that of AMA442. The reactions during the combustion tests were observed using a high-speed camera. The temperature during the reaction was measured using thermocouple attached to a sample vessel made of quartz tube. The results of the combustion test of AMA442 at 1 MPa (gauge pressure) showed that the reaction surface was dominated by a reaction that formed a bubble phase without flame, confirming the reaction temperature as previously reported. In ADN/MMAN, the reaction proceeded faster and hotter than in AMA442 while forming a flame. The results of combustion tests of the two-component system of ADN and AA showed that combustion did not continue under conditions of 1 MPa, and that the reaction proceeded with bubble phase formation and temperature history similar to that of AMA442 at 2 MPa and above. From the above studies, these results indicate liquid phase reaction of ADN and AA is preferential in the combustion reaction of AMA442, and that the effect of heat feedback from the MMAN-derived reaction is important for the reaction to continue., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA2230017004, レポート番号: JAXA-RR-22-006}, title = {温度計測に基づくアンモニウムジニトラミド/アセトアミド/モノメチルアミン硝酸塩混合系の燃焼反応解析}, year = {2023} }
