适应长期在轨的低温推进剂集成管理模块仿真研究

Numerical Simulation on Integrated Cryogenic Propellant Management Module for Long Duration On-Orbit

低温推进剂集成管理技术是面向未来火箭上面级长期在轨、多次启动任务的新技术手段。以上面级在轨滑行5天的奔月任务为背景,采用AMESim仿真平台搭建低温推进剂集成管理模块系统模型,开展滑行段工作过程仿真。仿真结果表明低温推进剂集成管理模块内组件工作占空比作为组件重要工作特征及工作参数,随姿控、电池充电等低温推进剂集成管理模块工作阶段变化而变化。

Integrated cryogenic propellant management technology provides a novel way for long duration on-orbit and multiple starts missions performed by upper stages in the future.Based on a trans-lunar mission containing 5 days coast,working process of integrated cryogenic propellant management module during coast is simulated with system model built using AMESim.Result shows that components duty cycles,which are critical working characteristics,vary with the change of integrated cryogenic propellant management module working process,such as attitude control and battery charging.
