摘　　要：为满足空间发动机及在轨推进剂流体传输中液体不夹气的要求,贮箱中需要设置推进剂管理装置,实现气液分离及液体获取。筛网通道液体获取装置是利用表面张力实现气液分离的装置。研究了地面环境下筛网通道液体获取装置压降模型,针对不同的液柱高度和流量开展计算,并通过地面出流试验对模型进行了验证。In order to meet the requirement that the liquid in the space engine and in-orbit propellant fluid transfer should not be filled with gas,a propellant management device should be set up in the tank to realize gas-liquid separation and liquid acquisition.Screen channel liquid acquisition device is the use of surface tension to achieve gas-liquid separation device.The pressure drop model of screen channel liquid acquisition device underground environment is studied.The calculation is carried out for different liquid column heights and flow rates,and the model is verified by ground outflow test.
