外弹道性能评估在电磁轨道炮系统的设计和研制中起着至关重要的作用。弹道性能评价可以看作是一个多准则决策问题，因为各种特征（也称为准则）对总体性能有影响。建立了一个复杂的仿真模型，包括六自由度力学、轨道炮构型、环境和空气动力学模型，以计算外弹道剖面。在此基础上，提出了基于云模型和层次分析法的综合弹道性能评估框架。选择了弹道速度、能量效率、飞行时间、飞行距离、过载、攻角和侧滑角稳定性等8个标准来确定外弹道性能。提出的方法产生每个准则的确定性程度，并将多准则集成到整体性能中。采用32兆焦耳发射能量和200公里打击距离两种方案对弹道性能进行评估，验证了所提方法的可行性。结果表明，在相同的发射能量为32 MJ的情况下，12公斤弹和16公斤弹的性能等级分别为I（优秀）和III（中等）。此外，增加弹体的质量可以提高在相同打击距离200公里内的性能。
Exterior ballistics performance evaluation plays a critical role in the design and development of the electromagnetic railgun system. The ballistics performance evaluation can be regarded as a multicriteria decision-making problem, for the reason that various characteristics, also termed criteria, have effects on the overall performance. A sophisticated simulation model, including six-DOF mechanics, railgun configuration, environment, and aerodynamics models are established to compute the exterior ballistics profile. Then a comprehensive framework based on cloud model and analytic hierarchy process method are proposed to evaluate ballistics performance. Eight criteria including ballistics velocity, energy efficiency, flight time, flight range, overload, attack angle, and sideslip angle stability are selected to determine exterior ballistics performance. The proposed approach yields the certainty degree of each criterion and integrates multicriteria into the whole performance. Two scenarios including 32-MJ launch energy and 200-km strike range are taken to generate alternatives for assessing ballistics performance, which demonstrate the proposed approach is feasible. Results show that in the same launch energy 32 MJ, the performance levels of 12- and 16-kg projectiles are I (excellent) and III (medium), respectively. Besides, gaining the projectile’s mass can improve performance in the same strike range 200 km.
