Modeling and simulation of radioisotope power system based on digital mock-up
摘要
Abstract
The Radioisotope Power System(RPS)is one of the indispensable energy systems for future deep space exploration missions.There are significant differences in the geometric dimensions,struc-tural design,and power ranges of in-service RPSs,leading to low modeling efficiency and difficulties in modeling.Therefore,a digital mock-up modeling and simulation technology for RPS is proposed.Its functions and research methodology were summarized and synthesized.Then,the process,meth-ods,and instructions for thermoelectric coupling analysis and radiation dose analysis in reverse engi-neering of in-service RPS were explained in detail.This technology were applied to the reverse engi-neering of typical RPSs such as the GPHS-RTG,"Chang'e-4"RTG,and MMRTG.Important results were obtained,including the thermoelectric performance,application schemes,and radiation dose distributions of these RPSs under deep-space and planetary-surface environments.The findings dem-onstrate the feasibility and general applicability of the technology,which can provide technical sup-port for future deep-space exploration missions.关键词
