Integrated propulsion and power generation device for space power system and method of operation thereof

Abstract

The present invention provides an integrated propulsion and power generation device for a space power system, comprising an attitude-orbit control engine module, a gas generator module, and a turbine-motor module. The attitude-orbit control engine module and the gas generator module are respectively connected to the propulsion The outlet of the gas generator module is connected to the turbine-motor module, and the gas blows the power of the turbine output shaft to drive the motor to generate electricity; the downstream of the turbine-motor module is connected to the electrical equipment to provide power for the electrical equipment. High power electric energy. The device of the present invention can meet the needs of space vehicles for power and high-power electric energy at the same time. In addition to providing the power required by the aircraft, it can also provide high-power electric energy when the aircraft has a high-power electric energy demand, so as to realize the integration of the propulsion system and the power generation system of the aircraft. The design is optimized, and propellant can be added to the device based on the propellant on-orbit replenishment technology, which can realize long-term in-orbit service of the device.

Description

technical field [0001] The invention relates to the technical field of space vehicles, in particular to a propulsion and power generation integrated device for a space power system and an operation method thereof. Background technique [0002] At present, the power required by space vehicles mainly depends on the power supply of solar panels. The power generated by solar panels is generally in the order of several thousand watts to tens of kilowatts, such as 1-4kW for the Shenzhou spacecraft, 20kW for the Dongwu platform, and 110kW for the International Space Station, which are suitable for power requirements. Small spacecraft can only work on the illuminated side, and the backlit side can only use the limited electric energy in the battery. Therefore, its capacity is limited, and the application of the aircraft load is greatly limited. For example, a space vehicle with a power requirement of more than 100kW requires a solar sail with an area of ​​several hundred square mete...
