Embodiment Construction

[0023] The present invention is a heating gasification device for a liquefied gas micro-propulsion system, comprising a first propellant storage tank 2, a second propellant storage tank 1, a first heat conduction module 5, a second heat conduction module 4, and a pressure reducer 6 , Surge tank 7, safety valve 3, pressure sensor 9 and filter 8, such as figure 2 Shown.

[0024] The first propellant tank 2 and the second propellant tank 1 are used to fill the liquid propellant. The liquid propellant is stored in the first propellant tank 2 and the second propellant tank 1 in liquid form. The stored pressure It is 0.84MPa, the total mass of liquid propellant is 0.6kg, and the mass of liquid propellant can be changed according to different mission requirements. A first heat conduction module 5 and a second heat conduction module 4 are installed on the first propellant tank 2 and the second propellant tank 1, respectively, the propellant inlet of the first heat conduction module 5 a...

Abstract

The invention discloses a heating gasification device for a liquefied gas micro-propulsion system. The device comprises a first propellant storage box, a second propellant storage box, a first heat conducting module, a second heat conducting module, a pressure reducer, a pressure stabilizing tank, a safety valve, a pressure sensor and a filter. In the device, a passive heating mode is adopted, and a satellite internal heat dissipation unit is used as a heat source, so that extra power consumption is not needed; and the gasification device has the advantages of reducing the production cost, fully gasifying the propellant and ensuring that the propellant completes work in the form of gas state, along with simple structure, a few elements and devices and high reliability and safety.

Description

Technical field [0001] The invention belongs to the technical field of liquefied gas micro-propulsion, and relates to a heating gasification device for a liquefied gas micro-propulsion system. Background technique [0002] As micro-nano satellites are more and more widely used, the liquefied gas micro-propulsion system is widely used on micro-satellites for attitude control and orbit maintenance and control with its unique advantages. Since the propellant is stored in liquid form in the liquefied gas micro-propulsion system, it needs to absorb heat during the gasification process to turn it into gas, and then it is ejected from the thruster of the propulsion system. If the heat absorbed during the gasification process is insufficient , Resulting in incomplete vaporization, part of the propellant will be ejected from the thruster in liquid form, resulting in a decrease in the specific impulse of the propulsion system and a waste of propellant, and may make the propulsion system un...
