 note = {近年，ヒドラジンを代替する低毒性一液推進剤候補としてアンモニウムジニトラミド（ADN）を基材としたイオン液体が注目を集めている．イオン液体はその高密度，高比推力，低毒性からヒドラジンに代わる一液推進剤として有望であるが，高粘度であるため微粒化が困難であり，点火特性や燃焼特性に課題があるため実用化には至っていない．本研究では，ADN系イオン液体に添加物を加えることで粘度を低下させ，微粒化特性を改善することを試み，性能低下を最低限に抑えつつ粘度を低下させられる添加物についての検討と，そのために必要な粘度測定実験およびCEA による化学平衡計算を行った．, In recent years, energetic ionic liquid based ammonium dinitramide (ADN) is drawing attention as green monopropellant alternate of hydrazine. Energetic ionic liquid is promising new monopropellant because it has high density, high specific impulse, and low toxicity. However, it is difficult to atomize due to its high viscosity. Therefore, it has ignition and combustion characteristics issue and not in practical use. In this study, we tried adding an additive to decrease viscosity of ADN-based energetic ionic liquid to improve its atomization characteristics. Viscosity measurement and chemical calculation by NASA CEA were performed to find suitable additive material for ADN-based green propellant. As a result, it is found that 20 wt% of methanol is suitable for additive because of viscosity, atomization characteristics, and exhaust characteristics velocity., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA2030016002, レポート番号: JAXA-RR-20-007},
