摘要
在载人航天工程交会对接任务中,基于对载人飞船推进剂剩余量在轨实时高精度测量需求的背景,采用理论分析和试验验证相结合的方法,研究了剩余量直接在轨测量技术原理、影响测量精度的因素及解决措施等问题。研究表明,在轨推进剂剩余量直接测量系统方案具有易于实现,测量精度高,同时能够实时、直观反映系统中各贮箱推进剂消耗情况等特点。
In the rendezvous and docking mission of the manned space flight program , there is a need for a high-precision on-orbit gauging method on the residual propellant in the manned space-craft .Theoretical analysis and the experimental verification were combined to study the principle and the effect factor of accuracy of the direct on-orbit gauging method and the improvement measures . The results showed that this direct measurement method is easy to implement and with high preci-sion, which can directly reflect the consumption of the propellant in real time .
