In order to effectively control the flying attitude and integrity of the rod-type killing element,combined with the rotation mechanism of the rod-type killing element,the influence of the oblique angle on the flying posture of the rod-type killing element was analyzed,and a product design method that can control the flying posture of the rod-type killing element was obtained.Combining the theoretical analysis and simulation calculation of the integrity of the rod-type killing element,by adjusting the pressure distribution and energy distribution on the rod-type killing element,the velocity vector distribution on the rod-type killing element is improved,and the deformation of the rod-type killing element is reduced,the rod-type killing element integrity control method was carried out.The rod-type killing element controllable flying test was carried out to verify the effectiveness of the rod-type killing element flying attitude and integrity control method.

The effectiveness evaluation of emergency repair on equipment plays an important role in repair force construction and repair decision-making.Aiming at the uncertainty and randomness of qualitative index quantification,based on the uncertainty quantification method and cloud model,an effectiveness evaluation model of emergency repair on equipment is proposed.The feasibility of the model is verified through an example.Based on the evaluation results,the advantages and disadvantages of the repair capacity building are analyzed,and the methods to strengthen the emergency repair efficiency are presented. The evaluation model provides method basis and technical support for comprehensively improving the building capacity of the emergency repair.
