A Thermal Control Device Adapted to Space Nuclear Thermal Propulsion System

Abstract

A thermal control device adapted to a space nuclear thermal propulsion system, comprising a low-temperature thermal insulation protection structure, a low-temperature hydrogen storage tank, a first heat exchanger, a space power generation module, a radiation radiator and a low-temperature refrigerator. The low-temperature thermal insulation protection structure is wrapped around the cryogenic hydrogen storage tank; the working medium hydrogen in the low-temperature hydrogen storage tank directly enters the nuclear thermal reactor one way, and the other way cools the nuclear thermal engine nozzle before entering the nuclear thermal reactor; the nuclear thermal reactor core The heat in the core is transferred to the first heat exchanger; the first heat exchanger transmits the waste heat of the core to the space power generation module; the space power generation module uses part of the heat to generate electricity, and the remaining heat is transmitted to the radiation radiator for space radiation heat dissipation; the space power generation module The generated electric energy controls the refrigeration of the low-temperature refrigerator to ensure that the working medium in the low-temperature hydrogen storage tank maintains a low-temperature storage state. The invention not only has the advantages of high reliability (no moving parts), good heat transfer and heat dissipation effect, but also has the characteristics of simple structure and comprehensive heat management, and has great application prospects.

Description

technical field [0001] The invention relates to a thermal control device adapted to a space nuclear thermal propulsion system, belonging to the technical field of advanced rocket thermal control. Background technique [0002] In order to realize deep space exploration and interplanetary manned missions, the future space transportation system should have higher performance, lower launch and operation costs and longer working life. Propulsion technology is one of the important supporting technologies for space activities. With its unique performance of high specific impulse and high thrust, nuclear thermal propulsion technology has the advantages of deep space exploration that chemical propulsion rockets cannot match. [0003] Nuclear thermal propulsion is a propulsion method that uses the fission energy generated by a nuclear reactor to heat the propellant (the propellant uses hydrogen as the working medium and coolant), and then the high-temperature and high-pressure workin...
