摘　　要：为研究1N ADN基推力器的瞬态启动性能,给推力器在轨使用提供参考,通过设计推力器高空模拟热试车系列工况,研究了催化床不同预热温度、喷注压力、不同寿命阶段推力器的瞬态启动性能,获得不同条件下推力器开机加速性t_(90)指标.结果表明1N ADN基推力器t_(90)随预热温度的上升呈现先减小后增大的趋势;推力器喷注压力降低,t_(90)变大;同时,研究了ADN基推进剂地面存储时长对推力器的瞬态启动性能的影响,实验结果显示在存贮时间内,推力器t_(90)指标保持稳定.To investigate the transient start-up of ADN-based 1N monopropellant thruster and provide the reference for the in-orbit application,through the Hot-firing test in high altitude simulated vacuum chamber,the influences of preheating temperature,injection pressure,working time on transient start-up are studied.The ADN-based 1N monopropellant thruster t_(90) is experimentally obtained with respect to various test conditions.It is shown that the t_(90) decreases first and then increases with the increase of preheating temperature.When the injection pressure drops,the t_(90) increases.The ignition test of ADN-based propellants stored for 4 years is investigated.The evaluation results indicate that the t_(90) is stable in the storage time.
