【摘要】 固体推进剂在不同状态下,诸如压力的突升、突降、波动状态下的燃速变化是国内外学者十分关注的.为此,出现了一些研究固体推进剂瞬态燃速的测试装置.激光药条燃面跟踪测量装置便是其中之一.本文对此装置的动态特性进行了理论研究,指出了测试系统的滞后对测试结果的影响,以及为减小滞后应采取的措施.更多还原

【Abstract】 Burning velocity response of solid propellant-step response of pressure, wave response of pressure,for example,is taken notice of the rocket scholars. Therefore the apparatus of instantaneous burning velocity forisol d propellant were developed,the laser tracking measurer of burning surface for solid propellant is one of these devices. This paper investigates the measurer for dynamical character and indicates that, the delay of device has an effect on the results of measurement,and determine measures must be taken to minimize the delay.更多还原
