| 摘 要： | 根据空气动力学和火箭发动机的相关理论，针对600 m长无缝滑车轨道，对搭载50 kg有效载荷、速度为45 m/s和搭载100 kg有效载荷、速度为200 m/s的两种双轨滑车进行了理论估算和试验验证。试验中，滑车的速度测试采用磁感应法、激光法和高速摄影法三种方法。试验结果表明，三种测试方法获得的滑车速度值一致，测试结果与理论计算值符合得较好。

| Abstract: | Base on aerodynamics and related rocket engine theories,two types of dual-rail sleds were designed and experimentally tested on a 600 m long non-gap sled rail.Velocities of sled were measured by using the three methods of magnetic induction,laser interferometry and high-speed photography respectively.Their speeds reached 45 m/s under 50 kg load and 200 m/s under 100 kg load respectively.Experimental results indicate that the velocities obtained by the three test techniques are consistent with each other and the measured velocities are in good agreement with the calculated results. |
