Problems solved by technology

However, liquefied gas is the propellant of the propulsion device because it needs to go through a gasification process to become gas to complete the work, so it needs to absorb a lot of heat. If the thermal control measures of the micro-propulsion device are not good, some propellant will be released from the thruster in liquid form. Ejection will reduce the working performance of the micro-propulsion device and waste propellant

Embodiment Construction

[0023] The present invention is a propane liquefied gas micro-propulsion device suitable for micro-nano satellites, mainly comprising a discharge valve 1, a first propellant storage tank 6, a second propellant storage tank 7, a first heat conduction module 8, and a second heat conduction module 9. Pressure reducer 10, surge tank 11, safety valve 5, thruster 18, pressure sensor A3, pressure sensor B13, filter 12 and control circuit box 19, such as figure 1 As shown, the above-mentioned components are all installed on the installation partition 20 . The shape of the installation partition 20 is the same as the shape of the cross section of the satellite where the micro-propulsion device needs to be installed, and there is no excessive connection and interference with other parts of the satellite, thus facilitating the installation, replacement and repair of the micro-propulsion device. The control circuit box 19 is installed on the other side of the installation partition 20 . ...

Abstract

The invention aims to provide a propane liquid gas micro propulsion device suitable for a micro-nano satellite. The device comprises an exhaust valve, a first propellant storage box, a second propellant storage box, a first heat-conducting module, a second heat-conducting module, a pressure reducer, a buffer tank, a safety valve, a thruster, a pressure sensor A, a pressure sensor B, a filter and a control circuit box. Propane serves as a propellant in the micro propulsion device, so the micro propulsion device is non-toxic and pollution-free; the micro propulsion device has the advantages of simple structure, low quality, low power consumption and high reliability; mounted on a mounting partition board, the micro propulsion device is convenient to be mounted and replaced; and because of no excessive relation and interference with other parts of the satellite, the micro propulsion device is convenient to be replaced and maintained.

Description

technical field [0001] The invention belongs to the technical field of liquefied gas micro-propulsion, in particular to a propane liquefied gas propulsion device suitable for micro-nano satellites. Background technique [0002] It is a contemporary trend to manufacture small satellites according to actual needs, and its purpose is mainly to save costs. Satellites with a weight of 100kg to 500kg are usually called small satellites, satellites with a weight of 10kg to 100kg are called microsatellites, and satellites with a weight of less than 10kg are called nanosatellites. Satellites below 1kg are called pico-satellites. The main features of micro-nano-satellites are compact development plan (short cycle), small shape, strong function and low cost. Over the past ten years, high-performance modern micro-satellites from various countries in the world have been successfully used in almost every field where satellites may be applied. Typical applications are in global communica...
