摘要
介绍了通过连续测量超声脉冲在推进剂中的反射时间,确定推进剂燃烧端面的位移,从而得到推进剂燃速的测试方法。它可以设置不同的压强变量条件来进行连续的实时燃速测量。叙述了国外超声波燃速测试技术在推进剂稳态燃速特性、非稳态燃速特性以及各种发动机燃速特性研究领域中的应用。评述了超声波燃速测试方法的特点和适用性,并建议国内研究机构开展该项技术的研究工作。
By measuring the reflection time of ultrasonic echo in the propellant continuously, the location of the burning propellant surface is identified, and the burning rate of propellant acquired. This ultrasonic method of measuring the burning rate is used to determine continuous in situ burning rate in different setting pressure variable condition. The application of the ultrasonic method of measuring the buring rate in the field of studying the steady-state and nonsteady-state burning rate characteristics of propellant and burning rate characteristics in various motor is introduced. The characteristics and adaptabilities of the method are evaluated, and a suggestion of developing this technology in internal institutes is presented.
