为解决未来空域窗射弹数量配置问题，依据未来空域窗理论最优射击密度，推导未来空域窗各瞄准点配置多发射弹情况下的毁伤概率公式，并对该公式特点进行分析。同时，基于该毁伤概率公式，提出预定毁伤概率情况下及预定毁伤概率导数情况下的射弹数量求解方法和预定射弹数量情况下的瞄准点数量求解方法。仿真实验表明，在同一条件下，通过该毁伤概率公式求得的毁伤概率与解析法求得的毁伤概率基本相同，两种情况下的射弹数量求解结果对目标的毁伤概率通过仿真验证与理论值基本一致，具有一定的可行性。

To determine the number of projectiles in Future Airspace Window (FAW), we deduced the damage probability formula for the future airspace window with many projectiles configured for each aiming point according to the optimal firing density of the future airspace window, and analyzed the feature of the formula. Based on the formula, the methods for calculating the number of the projectiles under predetermined damage probability or predetermined derivative of damage probability, and the number of aiming-points under predetermined number of projectiles, were provided.The simulation example showed that, the results of damage probability obtained though the formula were nearly the same as that obtained through analytic method. In both cases, the damage probability result of simulation was basically the same as theoretical result, which means that the method has certain feasibility.
