Throwable double-component annular storage tank for spacecraft

Abstract

The invention discloses a throwable double-component common-bottom type annular storage tank for a spacecraft. The annular storage tank comprises an annular storage tank body, a center cylinder and aseparation device. A first connecting ring, a second connecting ring and a ring section are symmetrically arranged on the annular storage box body, and the first connecting ring and the second connecting ring are provided with lug pieces. The center cylinder is provided with an upper end frame, a lower end frame and stringers; and the lug pieces and the stringers enable the annular storage tank body and the center cylinder to be connected through bolts to bear external loads together, the upper end frame and the lower end frame are separation surfaces, and the separation device is arranged onthe separation surfaces so that the annular storage tank body can have a throwing function. A connecting ring-single layer common-bottom assembly enables the annular storage tank body to form a double-component structural form, and a fuel agent and an oxidizing agent can be carried at the same time.

Description

technical field [0001] The invention belongs to the technical field of spacecraft storage tank structures, and in particular relates to a novel two-component common-bottom annular storage tank structure with the functions of throwing off and carrying. Background technique [0002] The spacecraft tank is an important part of the propulsion system, and its propulsion capacity is proportional to the volume of the tank; traditional spacecraft tanks are limited by the overall layout and load-bearing requirements, and most of them adopt cylindrical and spherical tank structures. It cannot be thrown away before the fuel is exhausted, resulting in low propulsion efficiency; in order to improve the propulsion capability of the payload, under the premise of a limited increase in weight, there is an urgent need for a vehicle that can greatly increase the fuel carrying capacity and can be thrown away after the fuel is exhausted. The two-component tank is used as the main power source or...
