| 摘 要： | 不少在轨卫星都使用半管理液体燃料贮箱,贮箱内的液体收集器上安装有表面筛网,可阻止贮箱内气体在发动机工作时通过收集器进入到液体燃料管路中.文章假设卫星液体燃料贮箱的底部收集器出现故障,无法阻止气体进入发动机管路.为确保卫星正常在轨运行,利用计算流体动力学数值仿真方法,对液体燃料贮箱在卫星姿态控制发动机工作时的运动规律进行...

| Abstract: | Most satellite propulsion subsystems employ propellant management device(PMD) in onboard oxidizer and fuel tanks for gas-free liquid propellant delivery during all mission phases.A kind PMD consists of pipes and drain windows,and the drain windows are covered with perforated sheet,which can provide capillary strength and thus prevent gas from entering the pipes and the engine.The failure of the perforated sheet of one drain window on the bottom of the fuel tank is envisioned.In order to avoid the gas enteri... |
