Kinetic energy interceptor （KEI） is mainly used to intercept medium-range and intercontinental ballistic missiles flying in the boost phase， ascent phase and midcourse， with the characteristics of high speed and high acceleration. Based on the research and analysis of literature and modeling simulation， this paper conducts reverse design and research on KEI missile's overall parameters， aerodynamic parameters and dynamic parameters， and simulates KEI missile's flight performance and interception performance. The results show that KEI missile can accelerate to 6 km/s in about 60 s. It also has the ability to intercept ballistic missiles in the boost phase/ascent phase for typical targets， and has reference significance for the development and research of domestic interceptor weapons.

In order to solve the growing pressure of large aircraft flight safety,a safety monitoring and training system of large aircraft was designed.Without affecting the original aircraft system,the data of the aircraft was collected.Combining the wireless communication,visualization and data processing technology,the data was shared with the ground facilities in real-time.In this way,the real-time sharing safety monitoring mechanism for flight and ground crew was set up.Based on data analysis,flight training and equipment health management system was built up,so as to promote the safety of large aircraft flight,the informatization of training,the intelligent of equipment maintenance.
