The embodiment of the invention provides a super-cooled liquid filling method of a large rocket, a storage medium and equipment, and relates to the field of large rockets, the filling method comprises the steps that a super-cooled liquid vacuumizing super-cooling line (100) is started, a super-cooled gas vacuum pump (48) arranged on the super-cooled liquid vacuumizing super-cooling line (100) is started, and the super-cooled gas vacuum pump (48) is started; extracting the evaporated supercooled gas in the ground supercooled liquid tank (44) by means of a supercooled gas vacuum pump (48); and when the temperature of the supercooled liquid in the ground supercooled liquid storage tank (44) is reduced to a first preset temperature, stopping extracting the supercooled gas in the ground supercooled liquid storage tank (44), and completing vacuumizing supercooling of the supercooled liquid in the ground supercooled liquid storage tank (44). The pressure of the supercooled liquid is reduced through vacuumizing, so that the supercooled liquid reaches the temperature below the boiling point temperature of the pressure, filling is completed at a time, and refilling is not needed.

    本发明实施例提供一种大型火箭的过冷液的加注方法、存储介质及设备,涉及大型火箭领域,所述加注方法包括:开启过冷液抽真空过冷线路(100),启动设于过冷液抽真空过冷线路(100)上的过冷气体真空泵(48),通过过冷气体真空泵(48)抽取地面过冷液贮箱(44)内的蒸发的过冷气体;当地面过冷液贮箱(44)过冷液的温度降低至第一预设温度,停止抽取地面过冷液贮箱(44)内的过冷气体,完成对地面过冷液贮箱(44)内的过冷液的抽真空过冷。通过抽真空降低过冷液的压力,使得过冷液到达该压力的沸点温度以下,且一次加注完成,不需要再补加。
