直升机载光纤制导导弹机弹相容性分析
|
摘要
针对光纤制导导弹挂装直升机载平台使用问题进行了机弹相容性分析。根据筒式发射方式,设计了光纤单端放线方案。综合考虑发射扰动及载机旋翼下洗流等影响因素,进行了导弹六自由度弹道仿真。应用微元法,分析了制导光纤下降速度。对发动机尾流场进行建模,确定了发动机尾焰影响区域。研究结果表明,光纤制导导弹与直升机载平台机弹相容性满足要求。文中的研究对于直升机载光纤制导导弹的工程研制具有参考意义。
To slove the applying problem of fiber-optic guided missile on the helicopter platform, compatibility analysis is studied.According to the launcher pattern, the fiber pay-off from single end is designed. Considering factors such as launch disturbance, downwash of the carrier rotor, and so on, the six-DOF missile trajectory simulation is conducted. Micro-element method is used to analyze the descending speed of the guiding optical fiber.The engine wake field is modeled to determine the area affected by the engine's exhaust plume. Research results show that compatibility between fiber-optic guided missile and helicopter platform meets the requirements. The research in this paper has reference significance for the engineering development of helicopter-borne fiber-optic guided missiles.
