从多步骤战斗行动系统平均动力学方程出发 ,以单机种攻击机机群为研究对象 ,提出估算作战效能指标值——完成任务所需的参加战斗行动的起始攻击机架数、所需总可比费用、击毁单位目标所需平均可比费用、每架攻击机击毁目标单位数及攻击机总的被击毁架数的计算数学模型 Based on the average kinetic equation of the multi-step combat operation system, taking the single-aircraft attack aircraft fleet as the research object, this paper proposes the evaluation of the combat effectiveness index value-the initial attack rack number required for the mission to participate in combat operations, Cost, the average comparable cost required to destroy a target, the mathematical model of the number of targets destroyed per target and the total number of destroyed aircraft
