Problems solved by technology

[0008] It can be seen from the figure that in order to realize the joint power supply between the two cabins, it is necessary to realize the voltage conversion through the ARCU and RACU. On the one hand, the weight of the power system of the space station is increased. consumes and reduces reliability

Embodiment Construction

[0040] A lunar probe consists of an ascending module (the first module) and a landing module (the second module), which mainly complete lunar surface sampling and lunar surface take-off tasks. Among them, the first cabin is the main cabin, which is required to be able to work under the orbital conditions of light and shadow alternately in the combination flight mode or the single flight mode, and the second cabin is the auxiliary cabin, which can be operated under the light and shadow alternately in the combination mode work under orbital conditions, and only work or not work during the light period after the cabin is separated.

[0041] The invention provides a combined power supply system for a double-cabin combined spacecraft, which includes: an ascending cabin (first cabin) power supply system and a landing cabin (second cabin) power supply system; figure 2 shown. The ascending cabin (first cabin) power supply system includes: a first solar battery array, a first chargin...

Abstract

The invention provides a dual-cabin combined type spacecraft combined power supply system and method; the combined power supply system comprises an ascending cabin power supply system and a landing cabin power supply system; the ascending cabin power supply system comprises a first solar cell array, a first charging diversion adjusting module, a discharge adjusting module and a storage battery pack; the landing cabin power supply system comprises a second solar cell array and a second charging diversion adjusting module; the power supply objects of the dual-cabin combined type spacecraft combined power supply system comprise each load in the spacecraft; the loads comprise a full-adjusting bus load and a non-adjusting bus load of the ascending cabin, and a full-adjusting bus load and a non-adjusting bus load of the landing cabin. The dual-cabin combined type spacecraft combined power supply system and method can ensure power supply needs in spacecraft combination flights, and can ensure power supply needs in cabin independent flight.

Description

technical field [0001] The invention belongs to the design field of spacecraft power supply systems, and in particular relates to a dual-chamber combined spacecraft combined power supply system and method. Background technique [0002] The dual-cabin composite spacecraft is a common form of space vehicles, and has been widely used in returnable satellites, spacecraft, and lunar exploration projects. As space exploration target tasks become more and more abundant, especially manned space exploration missions represented by the space station, and deep space exploration missions represented by lunar landing, patrol exploration, and sample return missions, the dual-cabin combination method is often used to complete the scheduled detection Task. my country's returnable satellites and "Shenzhou" series spacecraft are generally composed of orbital modules, propulsion modules, and returners. The Chang'e-3 probe is composed of a lander and a patrol device. The return device is compo...
