In this paper, by finding relevant literature on the development of equipment engineering projects, a comprehensive risk evaluation index system is constructed, and the relative weights between the primary and secondary indicators are calculated using the AHP method (hierarchical analysis).

In the live firing of mortar, the base plate is generally constructed at an angle of about 20° with the horizontal ground, so as to make the base plate more stable and improve the shooting accuracy. In order to explore the optimal matching angle between barrel and plate in live firing, a rigid-flexible coupling finite element model of a certain 82 mm mortar and soil is established. The dynamic response of launching is analyzed based on explicit solver under six working conditions with no. 4 charge, angle of fire 50°, angle of fire 60°, plate and horizontal ground 10°, 20° and 30° respectively. The relative change curves of the angle of firing of the first round of mortar under six conditions are obtained. It is found that when other firing conditions are consistent, the closer the angle between the plate and the barrel is to 90°, the smaller the relative change of the firing angle of the mortar is. When the angle between the plate and the barrel is to 90°, the relative change of the firing angle also reaches the minimum value, and the firing accuracy is the highest. The research results have reference value for the reliable use of mortars, the study of launch dynamic response and the design of related auxiliary devices.

The main content can be extracted from the complicated track information and summarized, so as to achieve the purpose of concise overview of the overall situation changes of the military chess deduction without losing the important details in the process of chess maneuver.The experiment shows that the trajectory clustering effect of the CTUW algorithm is more refined than that of the TRACLUS algorithm and the CTECW algorithm, and the computational complexity is lower. It can maintain a good clustering effect even when dealing with special trajectory data with abnormal maneuvering speed, special trajectory shape and trajectories overlap.
In this paper, the coverage model of Starlink constellation is established by means of the Satellite Simulation Kit (STK), and the coverage capability of Starlink constellation to Washington, Beijing, Taiwan and Kiev, which are located in north latitude 70 degree to south latitude 70 degree, is simulated and analyzed in detail. The simulation results show that the Starlink constellation can reach 100% coverage between the north latitude about 53 degree to south latitude about 53 degree, and the 1.5v Starlink satellites begin to cover the bipolar areas up to the present. Obviously, the Starlink constellation is developing steadily towards global coverage. According to simulation results, the Starlink constellation can achieve 24-hour full coverage in high latitudes such as Washington, Beijing and Kiev, and the coverage satellites number is large. But the Starlink constellation can’t achieve 24-hour full coverage in Taiwan and other low latitude regions. In conclusion, the Starlink constellation coverage capacity of all regions in the world is improving steadily and in high speed.
