Problems solved by technology
[0002] The storage tank is a container for liquid rockets to store propellants. The storage tanks in the prior art include manhole covers, manhole flanges, short shells, fork rings, barrel sections, box bottoms, etc.; the short shells are mostly made of aluminum alloy grid reinforcement structure , there is also a way of riveting stringers inside and outside the short shell; the fork ring is a structure of integral forging machining or segmental processing and tailor welding, connecting the bottom of the box and the barrel section; the barrel section is aluminum alloy light barrel or grid reinforced structure; the storage box The whole is made of aluminum alloy, which is light in weight, but there are problems of long production cycle and high production cost

The disclosure relates to the technical field of liquid rocket fuel storage tanks, and provides a fuel storage tank, which includes: a barrel section and two bottoms welded at both ends of the barrel section; each bottom is fitted with a short shell; the short shell includes Ring-shaped end frame and short shell panel; the end of the short shell panel away from the barrel section is connected to the end frame, and there are multiple reinforcing ribs connected in the short shell panel, and the multiple reinforcing ribs are uniform along the circumference of the short shell panel distribution, and each reinforcing rib extends to the bottom of the box; the barrel section, the bottom of the box, the short shell panels and the reinforcing ribs are all made of stainless steel. Compared with the aluminum alloy storage tank, the production cycle of the stainless steel fuel storage tank of the present disclosure is shortened by 2 / 3, and the production cost is greatly reduced, which is 1 / 10 of that of the aluminum alloy storage tank.
Description
technical field [0001] The present disclosure relates to the technical field of liquid rocket propellant storage devices, in particular to a fuel storage tank. Background technique [0002] The storage tank is a container for liquid rocket storage propellant. The storage tank in the prior art includes a manhole cover, a manhole flange, a short shell, a fork ring, a cylinder section, a box bottom, etc.; the short shell mostly adopts an aluminum alloy mesh reinforced structure , There are also ways of riveting stringers inside and outside the short shell; the fork ring is a structure of integral forging machining or segmented tailor welding, connecting the bottom of the box and the barrel section; the barrel section is an aluminum alloy light tube or a grid reinforced structure; The whole is made of aluminum alloy, which is light in weight, but has the problems of long production cycle and high production cost. SUMMARY OF THE INVENTION [0003] To address at least one of th...
