Abstract

To improve the hit probability and interception range of air defense guided projectilesand enhance the terminal defense capability, the work aims to propose a new scheme for air defense guided projectiles based on direct force control. A high-precision command guidance system was introduced to adjust the velocity direction of the projectile in real-time through the direct force control of pulse rockets, which was used for dynamic correction of shooting errors and improvement of hitting accuracy. Through mathematical modeling, simulation analysis, as well as Monte Carlo target shooting experiments, the effectiveness of the command guidance system +direct force control of pulse was verified. Compared with traditional unguided projectiles, the 20-meter point spread of unguided projectileswas improved to 2 meters for guided projectiles, resulting in a significant increase in single-shot hit probability. The required ratio of bullet-to-target speed(bullet speed/target speed) for interception decreased from 1.5 to 0.4, enabling the ability to intercept high-speed targets. The interception range increased from 2 kilometers to more than 4 kilometers. Considering actual combat requirements and costeffectiveness, mature technologies were emphasized during the design process, making it highly adaptable to various environments and characterized by low cost. In summary, the technology of direct force control has strong application value in the field of air defense guided shells.
