摘要:

本文论述了燃速预测的重要性,分析了发动机中实际燃速与预测燃速的差异,分别评述了SPP程序对燃速的处理方法、标准发动机预测燃速的要求、测试精度对燃速相关性的影响以及用燃烧理论模型进行燃速相关的问题.介绍了端面燃烧药的锥化现象和内孔燃烧药柱的驼峰效应.最后对开展燃速预测的研究工作提出了建议.

Abstract:

Some commentaries are made on following problems: importance of burning rate prediction, difference between real rate and predicted results, handling method for burning rate in SPP program, effect of measurement accuracy on the burning rate correlation.The taper tendency of cigeratte burning and the hump phenomena of inside-surface burning of grain are discussed. Some ideas about how to carry out the research work of burning rate prediction are suggested.
