200m自由飞弹道靶升级改造

Upgrading of 200 meter free-flight ballistic range at CARDC

200m自由飞弹道靶是国内唯一一座具备开展气动力、气动物理、材料抗粒子云侵蚀及超高速碰撞等地面试验研究的综合性弹道靶设备。为满足高超声速飞行器发展的进一步需求，2009年起气动中心对200m 自由飞弹道靶进行了升级改造，升级设备包括发射器系统、靶室/真空系统、测控系统、模型姿态测量系统等。改造后的发射器系统将新增203mm和120mm口径二级轻气炮，具备0．5～30kg模型发射速度0．3～5km/s 的发射能力；靶室由原来的Ф1．5m洞体升级至Ф3m洞体，同时配备新的真空设备，实现0～80km高度模拟；测控系统将扩大测试视场以满足大模型测控需要；模型姿态测量系统除阴/纹影照相系统外，还将新增双目前光成像定位系统、脉冲X射线成像测量系统等测试设备。改造后的200m自由飞弹道靶将成为大中小口径发射器配套齐全，兼具气动力特性、材料抗粒子云侵蚀、高速/超高速碰撞等试验能力的综合性弹道靶设备。

Two-hundred meter free flight ballistic range is the only one comprehensive ballistic range equipment in China that can carry out aerodynamics test,aero physics test,erosion and hypervelocity impact.In order to meet the demand of the hypervelocity aero craft development, the equipment has been upgraded since 2009 .The upgraded equipment includes launch system, the chamber and vacuum system,velocity measurement and control system,photogram and orientation system.The launch system will be equipped with 203mm and 120mm bore two-stage light-gas guns.The weight of the model that the launchers can launch are from 0.5kg to 30kg, and the model velocity is from 0.3km/s to 5km/s.The diameter of the tank will be increased from 1.5m to 3m.At the same time,The range will equipped with new vacuum system,which can realize the simulation of altitude from 0km to 80km.Velocity measurement and control system will meet the big model measured requirement.Except shadow and schlieren equipment,the position system of double eyes front light imaging,X-ray imaging and measurement system will be constructed.After upgrading,from small to big bore two-stage light-gas guns will be equipped in the launcher system of 200m free-flight ballistic range,and the test abilities of the range will be improved in aero-dynamic test,erosion,high and hypervelocity impact test.
