The invention discloses a propellant storage tank for aerospace. The propellant storage tank comprises a high-pressure gas tank, a first exhaust pipe is welded to the outer wall of one side of the high-pressure gas tank, a pressurizer is fixed to the outer wall of the first exhaust pipe, a pressurizing valve is installed on the outer wall, away from a pressure reducer, of the first exhaust pipe, and a second exhaust pipe is welded to the outer wall of one side of the lower portion of the first exhaust pipe; a material box is welded to the outer wall of the bottom of the high-pressure gas box,a heat insulation plate is welded to the inner wall of the middle of the material box, a fuel tank is arranged on the outer wall of the top of the heat insulation plate, a fuel filling pipe is weldedto the outer wall of one side of the top of the fuel tank, an oxidant box is arranged on the outer wall of the bottom of the heat insulation plate, and an oxidant filling tube is welded on the outer wall of the top side of the oxidant box. According to the invention, the temperature of the oxidant can be controlled through refrigeration sheets mounted in the refrigeration tank, the oxidant for spaceflight is in a liquid state, and the liquid oxygen cannot be gasified only in an extremely low temperature state, so that the liquid oxygen can be continuously cooled through the refrigeration effect of the refrigeration sheets.
本发明公开了一种航空航天用推进剂贮箱,包括高压气箱,所述高压气箱一侧外壁焊接有第一排气管,且第一排气管外壁固定有加压器,所述第一排气管远离减压器的外壁安装有增压阀门,且第一排气管下部一侧外壁焊接有第二排气管,所述高压气箱底部外壁焊接有料箱,且料箱中部内壁焊接有隔温板,所述隔温板顶部外壁设有燃料箱,且燃料箱顶部一侧外壁焊接有燃料加注管,所述隔温板底部外壁设有氧化剂箱,且氧化剂箱顶部一侧外壁焊接有氧化剂加注管。本发明通过制冷槽内部安装的制冷片可以对氧化剂进行温度控制,航天用的氧化剂都是处于液体状态,只有在极其低温的状态下液氧才不会气化,因此通过制冷片的制冷效果可以对液氧进行持续降温。
