A spatial test aircraft ground propellant tank

The present invention discloses a ground test spacecraft propellant tank, comprising a housing open at one end of the tank, the cylinder chamber is provided for storing the liquid propellant in the tank housing, sway the anti-rotation member, the fixing member, the fixing member fixed to an upper end opening of the tank housing; the housing fixing member inserted into the tank through the lower liquid chamber cylinder, the gap between the fixing member and the liquid chamber is provided with a transversely elastic cylindrical member; said liquid chamber cartridge the lower end of the tank body is fixed directly to the housing, the lower liquid chamber also has a cylindrical body sway the anti-rotation member. Advantageous effects of the above aspect of the present invention are as follows: simple structure, technically sound, light weight, low manufacturing cost, the fill volume of propellant can be adjusted according to the use of very flexible and can adapt to large angle fluctuation, the structure is very strong.
