The invention provides a fuel storage tank for a hypersonic aircraft and a control method of the fuel storage tank, and the fuel storage tank for the hypersonic aircraft comprises a shell which is internally provided with a first accommodating cavity; an air inlet communicated with the first accommodating cavity is formed in the shell; a first oil port is further formed in the shell; the elastic bag body is mounted in the first accommodating cavity; a second containing cavity used for containing liquid fuel is formed in the elastic bag body. A second oil port communicated with the second accommodating cavity is formed in the elastic bag body; the second oil port and the first oil port are in sealed butt joint to form an oil conveying channel. The gas inlet is used for introducing gas to increase the pressure in the first containing cavity, so that the elastic bag body is pressed and deformed to extrude the liquid fuel in the second containing cavity, and the liquid fuel is output from the oil conveying channel. Fuel is supplied to the aircraft in an extrusion type supply mode, a pressure accumulator is not adopted, and the fuel conveying channel can continuously and stably supply fuel to the aircraft.
本申请提供一种高超音速飞行器用燃料贮箱及其控制方法,所述高超音速飞行器用燃料贮箱包括:壳体,壳体内部具有第一容纳腔;壳体上开设有与第一容纳腔连通的进气口;壳体上还开设有第一油口;弹性囊体,弹性囊体安装在第一容纳腔内;弹性囊体内部具有用于容纳液体燃料的第二容纳腔;弹性囊体上开设有与第二容纳腔连通的第二油口;第二油口与第一油口密封对接并形成输油通道;进气口用于通入气体,以增大第一容纳腔内的压力,使弹性囊体受压变形以挤压第二容纳腔内的液体燃料,从而使液体燃料从输油通道输出。本申请采用挤压式的供给方式为飞行器供给燃料,且不采用蓄压器,输油通道可以连续稳定地为飞行器供给燃料。
