specific Embodiment approach 1

[0006] Specific Embodiment 1: The present embodiment will be specifically described below with reference to FIG. 1 . This embodiment consists of the following steps: 1. The solar energy is converted into electrical energy by the solar panel in the solar independent power supply system 1, which is supplied to the electrolyzed water system 2 and the hydrogen and oxygen purification and pressurization system 3; 2. Electrolyzed water System 2 uses the electric energy output by solar independent power supply system 1 to decompose water into hydrogen and oxygen; 3. Hydrogen and oxygen purification and pressurization system 3 dries and boosts hydrogen and oxygen for use. Hydrogen and oxygen are used as the working fluid of the engine to generate thrust.

[0007] The solar independent power supply system 1 is composed of a solar battery sail 1-1, a controller 1-2, a storage battery 1-3 and an inverter 1-4, and the output end of the solar battery sail 1-1 is connected through the contr...

specific Embodiment approach 2

[0010] Specific Embodiment 2: The present embodiment will be specifically described below with reference to FIG. 1 . The difference between this embodiment and Embodiment 1 is that the electrolyzed water system 2 also includes a gas flow feedback circuit 2-3 and a gas pressure feedback circuit 2-4, and the gas flow feedback circuit 2-3 collects the oxygen in the electrolytic cell 2-2 and the flow of the hydrogen outlet to control the current value output by the switching power supply 2-1, so that the flow of the oxygen and hydrogen outlets of the electrolytic cell 2-2 remains within the allowable range; the gas pressure feedback circuit 2-4 collects the electrolytic cell 2- 2’s oxygen and hydrogen outlet pressures to control the current value output by the switching power supply 2-1, so that the pressure of the oxygen and hydrogen outlets of the electrolyzer 2-2 remains within the allowable range; their two functions are to electrolyze water When the generated gas pressure or ...

specific Embodiment approach 3

[0011] Specific Embodiment Three: The present embodiment will be specifically described below in conjunction with FIGS. 2 and 3 . The difference between this embodiment and the first embodiment is that the electrolytic cell 2-2 is an alkaline electrolytic cell, a polymer film electrolytic cell or a solid oxide electrolytic cell.

[0012] Fig. 2 is a structural schematic diagram of a polymer film electrolyzer. The polymer film electrolyzer is mainly composed of an anode 6, a cathode 7 and a proton exchange membrane 8. The proton exchange membrane 8 usually forms an integrated structure with the electrode catalyst 9. In this structure, a porous platinum material is used as the structure of the electrode catalyst 9. The anode 6 and the cathode 7 are closely attached to the surface of the proton exchange membrane 8 . The proton exchange membrane 8 is mainly composed of nafion and contains SO3H. Water molecules are decomposed into oxygen and hydrogen ions at the anode, and the hy...

Abstract

The invention which provides a preparation method for solar energy water base high-pressure high-purity oxy-hydrogen fuels used in spacecrafts relates to the preparation method for fuels used in spacecrafts so as to overcome the problems of low efficiency, great danger and serious pollution, etc., in conventional chemical promoting systems by using the prepared hydrogen and oxygen as promoting agents for the promoting systems. The invention comprises the following steps: firstly, solar energy battery panels in a solar energy separate power supply system (1) convert the solar energy into electric energy for an electrolyzed water system (2) and a purification and pressure increasing system of hydrogen and oxygen (3); secondly, the electrolyzed water system (2) decomposes water into hydrogen and oxygen by making use of the electric energy output by the solar energy separate power supply system (1); thirdly, the purification and pressure increasing system of hydrogen and oxygen (3) dries and boosts pressure on the hydrogen and oxygen for future use.

Description

technical field [0001] The invention relates to a fuel preparation method for space vehicles. Background technique [0002] The 21st century is the century of military aerospace. In future wars, near-body space will become a new commanding height and have a revolutionary impact on modern warfare. Human beings will launch an unprecedented competition in near-body space, with the development and utilization of abundant space resources and competition for control as the main content, and aerospace weapons and equipment will be developed more rapidly. The propulsion system is an important guarantee for the normal work and operation of the mobile aircraft, so it is also the focus of research and development in various countries. Propulsion systems can be divided into conventional chemical propulsion systems and unconventional electric, nuclear, laser and other propulsion systems according to the way of thrust generation. In maneuvering space platforms, conventional chemical pr...
