美国Purdue大学火箭发动机实验室在J.R.Osborn教授领导下,发展了GDP及PEM模型。为了研究推进剂的能量特性以及温度和压力敏感度,必须测量推进剂的燃速和火焰温度。为此,设计和安装了一套伺服调节机构,使燃烧表面在工作过程中,自始至终保持在一个固定位置上。这样就可以测量燃烧的瞬时速度。在这同时,有一套能自动测量和记录的装置用来测量火焰的温度。
The Rocket Engine Laboratory at Purdue University in the United States under the leadership of Professor J.R.Osborn, the development of GDP and PEM model. In order to study the energy characteristics of propellants as well as temperature and pressure sensitivities, it is necessary to measure the propellant firing rate and flame temperature. To this end, a servo adjustment mechanism has been designed and installed so that the combustion surface remains in a fixed position throughout its operation. This will measure the instantaneous speed of combustion. At the same time, there is a set of automatic measurement and recording device used to measure the temperature of the flame.
