摘　　要：通过热加速老化、自然存储、湿热环境金属相容性(腐蚀性)试验,研究了一种硝酸酯液体推进剂(OTTO-II)的长储性能。结果表明:按温度系数法,OTTO-II常温(30℃)下的预测安全贮存寿命不少于11 a;自然环境下贮存2.4 a各组分无明显变化;在60℃、85%RH环境下储存30 d产品中的H2O含量达到饱和,但硝酸酯和安定剂含量未变。在(60℃、85%RH、30 d)温湿条件下,6种不同表面加工工艺的镁金属试片均不被OTTO-II腐蚀;仅个别镁金属试片可能因表面加工工艺不当,对丙二醇二硝酸酯(PGDN)的分解产生一定的促进作用。T he long-term storage properties of a notric acid ester（ O T T O-II） w ere investigated by elevated-temperature aging test,natural environment storage test,hydrothermal environment metal compatibility（ causticity） test. R esults show that its safe storage life estimated at30 ℃ is not less than 11 a and its ingredients unchanged after stored for 2. 4 a under the natural environment. T he w ater in O T T O-II is saturation after storied under the hydrothermal environment conditions of 60 ℃,85% R H,and 30 d,but the content of the stabilizer and notric acid ester is stable. T he magnesium flakes in the hydrothermal environmental,machined by 6 different w ays,are not corroded by O T T O-II.O nly one flake catalyzes the decomposition of PGDN because of unsuitable machining technique for metal surface.
