摘　　要：针对含硼富燃料推进剂金属含量大,燃烧后残渣导电,用普通燃速仪测试不易获得数据的问题,对靶线法测速仪的计时系统进行了改进。改进后的计时系统对测试环境的要求降低,从而提高了测试效率和精度。Boron-based fuel-rich propellent contains metal and its combustion residue is of electro-conductive, so the burning rate data of the propellant are difficultly gained by use of an ordinary strand burner method. The problem is solved by improving the recording time system of the testing apparatus. The results show that the new timing device is less dependent on the testing environment conditions, so its testing efficiency and reliability are improved.
