超远深空探测任务的能源动力方案

Ultra Deep Space Exploration Mission and Power Project

我国开展了大量深空探测方面的研究工作,但超远距离(大于几十个AU)深空探测器在我国尚未实际发射,需综合考虑飞行空间环境、任务寿命和重量限制等约束条件,对能源系统进行合理设计,以保证探测的任务需求。通过对国外相关任务的调研与分析,并结合我国现有的技术基础,选择以空间核动力系统作为能源动力解决方案,同时关注其他概念推进设计,提出了总体任务设想和后续需要开展的关键技术攻关方向,主要为高效的"核能+全电推"系统技术、星际飞行技术及测控技术。对我国后续超远深空探测任务的研究及实施具有一定指导意义。

China has carried out a lot of research work in the field of deep space exploration(more than dozens of AU)but the ultra deep space exploration mission has not yet been launched. Interstellar exploration can greatly enhance the space exploration,improve the self-sufficiency of data required by space science research, and reach the international leading level in the world. Far away from Jupiter, satellites will get less solar mediation intensity, how to generate electricity and how to prevent the satellites too cold should be considered. So we need to design a reasonable energy system by considering the limit conditions about flight space environment, task life and weight. Based on the investigation of relevant tasks in foreign countries and the existing technical basis in China, the space nuclear energy system is selected as the main power solution. Meanwhile, the conceptual propulsion design is also considered, and the task assumption and key technologies to be developed are put forward.
