A reusable intelligent liquid propellant tank device

Abstract

The invention discloses an intelligent liquid propellant storing box device capable of being repeatedly used. An intelligent shape memory alloy diaphragm restorable after deformation and capable of being repeatedly utilized is adopted, and the defects that a metal diaphragm built in a spaceflight propellant storing box cannot be restored after overturning deformation and cannot be repeatedly utilized are overcome. The device is composed of a pressure applying storing box shell, a sealing ring, the shape memory alloy diaphragm and a liquid discharging storing box shell; and in the work processof the shells, according to the shape memory alloy diaphragm, the diaphragm is symmetrically and stably overturned to the lower half sphere from the upper half sphere to discharge liquid. After the liquid is discharged, the temperature of the shape memory alloy diaphragm after being deformed rises, the diaphragm restores to the initial state, and at the moment, the storing box device can be used for the second time. The device has the beneficial effects of being simple in connection, high in reliability, capable of being repeatedly utilized and the like, and the device, formed in this manner,restorable after deformation can serve as a liquid propelling device to be applied to the fields of aerospace, ships, nuclear power and the like.

Description

technical field [0001] The invention relates to a propellant storage tank device for providing fuel and oxidant for an engine. After the propellant storage tank structure squeezes the propellant out of the storage tank, the built-in diaphragm returns to its original shape, so it can be used repeatedly. The invention belongs to the field of intelligent structures, in particular to an automatic recovery and reusable device. Background technique [0002] Shape memory alloy is deformed by external force at a certain temperature, and when the external force is removed, it still maintains its deformed shape, but when the temperature rises to a certain temperature, the alloy will automatically return to its original shape before deformation. The previous effect of shape retention memory is called shape memory effect. The propellant diaphragm tank is an important part of the space vehicle, in which the built-in metal diaphragm is turned over and deformed under the action of air pre...
