摘　　要：机载激光武器可以主动防御来袭导弹,大幅提升作战飞机的生存能力。为了具备更远的打击距离,激光武器需要尽可能大的发射镜直径,但几何尺寸较大的发射转塔会对飞机的气动和隐身性能产生不利影响,降低飞机的战场生存能力。利用计算流体力学和物理光学法,分析发射转塔直径对飞机的气动性能和隐身性能的影响,并采用基于agent的作战仿真方法研究发射转塔直径对飞机在突防作战中作战效能的影响。结果表明:飞行速度随着发射转塔直径的增大有小幅度降低,降低幅度在2%以内;30、50和70 cm的发射转塔直径分别导致飞机的头向RCS 64%、173%和282%的增加;对于作战效能而言,激光武器发射转塔的尺寸并非越大越好,相对于无防御措施的无人机执行突防任务,50 cm的发射转塔直径可以提高77.2%的任务成功率,是三种方案中最高的。Airborne laser weapon system can increase the survivability of the aircraft by active defense.In order to obtain longer fire range,a large diameter of the airborne laser weapon turret is required,which may cause negative influence to the aircraft.The influence of turret diameter on aerodynamic and stealth performance of the aircraft is analyzed by means of computational fluid dynamics method and physical optics method.And the influence of turret diameter on combat effectiveness is analyzed with agent-based combat simulation.The results show that the increase of turret diameter will lead to a slight decrease of aircraft speed,while the influence quantity of laser turret to aircraft speed is within 2%.In the meantime,the increase of turret diameter increases the front RCS(Radar Cross Section)of the aircraft,an diameter of 30,50 and 70 cm of laser turret could lead to an increase of 64%、173%and 282%of the aircraft RCS.The 50 cm diameter design could increase the most mission effectiveness,which is 77.2%.
