Embodiment Construction

[0029] specific implementation plan

[0030] The present invention proposes a capsule type storage tank suitable for high-concentration hydrogen peroxide, comprising a storage tank casing 1, a filling and leakage assembly 2 and a membrane liquid capsule 3, such as figure 1 shown.

[0031] The tank shell 1 is a cylindrical shell, and the upper and lower ends are constricted openings. The tank shell 1 is made of LD10 as a whole, and the surface is anodized, compatible with hydrogen peroxide grade 2. The lower end of the storage tank shell 1 is used as a pressurized gas inlet, and a pressurized pipeline interface 101 is designed to connect the pressurized pipeline so that the pressurized gas passes into the storage tank shell 1 through the pressurized pipeline interface. The upper end of the tank shell 1 serves as the liquid propellant outlet, and is designed with a mounting flange 102 for installing the filling and leaking assembly 2 .

[0032] The filling and leaking assembl...

Abstract

The invention discloses a bladder-type storage tank for high concentration hydrogen peroxide, which comprises a storage tank shell body, an injection discharging component and a thin film liquid bag, wherein the injection discharging component is coaxially mounted inside the storage tank shell body; the injection discharging component is constituted of an end cover, a multi-hole pipe, a fixed disc and a support plate; the end cover and the fixed disc are respectively welded on two ends of the multi-hole pipe; the end cover is connected to a storage tank outlet flange; liquid inlet / outlet channels are respectively opened on the end cover and the fixed disc; the multi-hope pipe is provided with dense small holes in order to make sure the flow area of a propellant; the fixed disc and a support disc are used for mounting the thin film liquid bag and fixing the injection discharging component; the support disc is designed with a diffusion hole in order to prevent the thin film liquid bag from being impacted directly by the pressurized gas; and the thin film liquid bag is uniform in applied force. The advantages are that the bladder-type storage tank is suitable for storing hydrogen peroxide propellant for a long time; the hydrogen peroxide propellant and the pressurized gas are separated by the thin film liquid bag; the pressurized gas is wide in choice; and the hydrogen peroxide won't be catalyzed and decomposed by the pressurized gas.

Description

technical field [0001] The invention belongs to the field of delivery systems for rocket engines, and specifically relates to a bladder-type storage tank suitable for high-concentration hydrogen peroxide, which is used for storage and delivery of high-concentration hydrogen peroxide. Background technique [0002] The use of non-toxic, non-polluting and storable propellants in aerospace power systems is a future development trend. In recent years, research has focused on green propellants. Hydrogen peroxide has the advantages of non-toxic, non-polluting, high density, easy storage, high specific heat, large volume expansion and heat generated by decomposition, and is an ideal green propellant. Hydrogen peroxide can be used not only as an oxidant for bicomponent liquid rocket engines and solid-liquid hybrid rocket engines, but also as a single component propellant, with broad application prospects. Therefore, research on hydrogen peroxide propulsion technology is being carrie...
