In order to test whether the performance of the composite radome of the aircraft nacelle,that has been in service for many years,meets the requirements for continued use,it is necessary to conduct a comprehensive evaluation the aging performance of the radome.By using the knocking method combined with finite element simulation analysis and relevant laboratory tests,the ageing performance of the radome has been comprehensively evaluated.The results show that the performance of radomes meets the index requirements.At the same time,combined with the subsequent use of radomes by the users,it is evident that the results of the comprehensive evaluation method of radome aging performance proposed are credible.
