摘要:
为保证应用于深空探测器的同位素热源的安全性和可靠性，开展了深空探测器同位素热源环境试验技术研究。通过对同位素热源全寿命周期内各任务剖面的系统分析，总结得出了同位素热源环境试验项目，并对这些项目进行了研究及模拟实验，具体包括：高温-离心、高温-冲击、高温-振动等热-力复合环境试验技术，空气动力学加热、热冲击试验、发射场火灾事故地面模拟实验等异常环境安全性试验技术。通过以上研究建立了同位素热源鉴定级环境可靠性试验及异常环境安全性试验能力，为深空探测器同位素热源研制任务提供了技术支撑。
Abstract:In order to ensure security and reliability of the radioisotope heat source for deep space exploration,the research on the environment testing technology of the radioisotope heat source is conducted. The test items are concluded by analyzing the mission profile during the whole life of the radioisotope heat source for deep space exploration. The high temperature-centrifuge,high temperature-impact,high temperature-vibration compound environment testing technologies are studied,and the technologies of ground simulation test for launch site fire accident,aerodynamic heating and thermal shock is also discussed in detail. The capacity of the environment reliability test and abnormal condition security test for the radioisotope heat source has been set up. Then,the environment test is performed which can provide support for the research of radioisotope heat source for deep space exploration.
