The invention relates to the technical field of measurement, in particular to an in-orbit propellant surplus measuring method for an aerospace metal diaphragm storage tank, which is suitable for measuring the propellant surplus of a metal diaphragm storage tank, namely a pressurized gas and liquid propellant separation structure storage tank, the measuring device is simple in arrangement, the measuring process is convenient, and the measuring accuracy is high. The residual volume of the propellant can be calculated by comparing with a metal diaphragm vertex displacement-liquid cavity residual volume model obtained by a ground test according to the discharge efficiency of the propellant of the metal diaphragm storage tank, so that the high-precision measurement of the residual propellant in the in-orbit full working process of the spaceflight metal diaphragm storage tank is met.

    本申请涉及测量技术领域,具体而言,涉及一种航天金属隔膜贮箱在轨推进剂剩余量测量方法,适用于金属隔膜贮箱,即增压气体和液体推进剂分隔结构贮箱的推进剂剩余量的测量,测量装置设置简单,测量过程方便,通过与地面试验得到的金属隔膜顶点位移‑液腔剩余容积模型做对照,再根据金属隔膜贮箱推进剂的排出效率,就能够计算得到推进剂的剩余体积,满足了航天金属隔膜贮箱在轨全工作过程中剩余推进剂的高精度测量。
