Abstract

Abstract

X-band pulsed space Traveling Wave Tube (TWT) is mainly used in such radar system as light-weight SAR, which is required to have high power, high efficiency and high reliability. The output structure is an important part of the TWT, and its reliability not only affects the output power of TWT, but also influences the stability and reliability of the TWT. In this paper, the reliability of the output structure of an X-band pulsed space TWT is studied. The thermal and structural reliability is studied by means of multi-physics coupling including electrical and magnetic. The shock resistance ability of the output structure is improved according to the analysis results. Furthermore, in the course of above 1000 hours aging and space environmental test, the output structure has high reliability, meeting the space environment test and use requirements.
