飞机易损性分析与评估是指对飞机在战斗状态下遭受攻击后受损的难易程度的评价,是衡量飞机战斗性能的重要指标。研究飞机易损性对于飞机高生存力设计和飞机战伤预测评估具有重要意义。本文首先简要介绍了飞机易损性分析的一般方法与流程,收集并整理了美军飞机易损性实弹测试的历史沿革和条件建设现状,同时以F-35整机、F135发动机和C27机翼油箱为例介绍了易损性实弹测试的方法。可以发现,在制度层面上,美军已经形成了由实弹测试机构、装备供应商以及军队用户三方联合协作的标准化、制度化的飞机易损性实弹测试体系;同时,其所建立的实弹测试平台力求更加真实地模拟战场环境,能够有效实现部件/子系统在特定工况下使用功能的监控,测试结果能够有效支撑飞机毁伤树与部件/子系统毁伤判据的构建,从而确保测试结果可以有效指导飞机的低易损性设计。 相似文献

We study how changes to the composition and employment of the US Navy combat logistic force (CLF) influence our ability to supply our navy worldwide. The CLF consists of about 30 special transport ships that carry ship and aircraft fuel, ordnance, dry stores, and food, and deliver these to client combatant ships underway, making it possible for our naval forces to operate at sea for extended periods. We have modeled CLF operations to evaluate a number of transforming initiatives that simplify its operation while supporting an even larger number of client ships for a greater variety of missions. Our input is an employment schedule for navy battle groups of ships operating worldwide, extending over a planning horizon of 90–180 days. We show how we use optimization to advise how to sustain these ships. We have used this model to evaluate new CLF ship designs, advise what number of ships in a new ship class would be needed, test concepts for forward at‐sea logistics bases in lieu of conventional ports, demonstrate the effects of changes to operating policy, and generally try to show whether and how the CLF can support planned naval operations.

通过对空中兵力的合理编组,实现作战资源的优化配置是提升兵力作战效能的有效途径。针对现代空战编队对抗过程的特点,从战术企图和信息优势角度提出了编队目标威胁评估方法。以编队目标为研究对象从宏观上调配己方作战资源,提出了作战资源成本和兵力调度成本2种兵力编组成本,在此基础上建立了资源约束条件下的兵力编组优化模型,并采用改进PSO算法对模型进行求解。作战想定仿真结果表明兵力编组模型能够有效解决空战兵力分配问题。 相似文献

This article develops a Lanchester-type model of large-scale conventional ground combat between two opposing forces in a “sector”. It is shown that nonlinear Helmbold-type equations of warfare with operational losses may be used to represent the loss-rate curves that have been used in many aggregated-force models. These nonlinear differential equations are used to model the attrition of combat capability (as quantified by a so-called firepower index) in conjunction with a rate-of-advance equation that relates motion of the contact zone (or FEBA) between the opposing forces to the force ratio and tactical decisions of the combatants. This simplified auxiliary model is then used to develop some important insights into the dynamics of FEBA movement used in large-scale aggregated-force models. Different types of behavior for FEBA movement over time are shown to correspond to different ranges of values for the initial force ratio, for example, an attack will “stall out” for a range of initial force ratios above a specific threshold value, but it will “break out” for force ratios above a second specific threshold value. Such FEBA-movement predictions are essentially based on being able to forecast changes over time in the force ratio. 相似文献

It is proposed to describe multiple air-to-air combat having a moderate number of participants with the aid of a stochastic process based on end-game duels. A simple model describing the dominant features of air combat leads to a continuous time discrete-state Markov process. Solution of the forward Kolmogorov equations enables one to investigate the influence of initial force levels and performance parameters on the outcome probabilities of the multiple engagement. As is illustrated, such results may be useful in the decision-making process for aircraft and weapon system development planning. Some comparisons are made with Lanchester models as well as with a semi-Markov model. 相似文献

Contemporary network organizational structures have gradually developed over the last decades of the twentieth century. These new structures are challenging the traditional hierarchical structure form in a number of venues. In conflict and war, they made their potentials unequivocally known on 11 September 2001 via Al Qaeda's strategic suicide bombings against the United States. To better understand the military potentials of networks, an operational combat analysis of the Al Qaeda network was conducted. This analysis, a modification of weapons systems analysis, focused on network speed, along with offensive, defensive and combat multiplier attributes. Such analysis allows for a better understanding of the military capabilities and vulnerabilities of non-state OPFORs (opposing forces) and our own emergent counter-insurgency networks. 相似文献

One of the most important issues facing the post‐Cold War U.S. defense establishment concerns the future allocation of combat tasks and responsibilities among different branches of the armed forces. The challenge is to reduce unnecessary redundancy across roles and missions when resources are highly constrained, without compromising military effectiveness. Defining the policy problem as one of resource allocation rather than operational effectiveness, we develop a methodology for allocating roles and missions. Our methodology focuses at the highest level of force aggregation and uses a mathematical programming model to produce cross‐service cross‐mission trade‐offs that will yield the best total force combat and non‐combat potential within resource consumption constraints. 相似文献
