摘要
对固体推进剂的动态燃烧进行了理论分析和实验研究,建立了推进剂动态燃烧的理论模型,并推导出了推进剂动态燃速公式.实验研究中发现推进剂燃烧过程中压强变化率对其燃速有显著影响,且压强变化率越大,影响也越明显;动态燃速要比静态燃速最多可高出40.2%(MDB)和17.7%(复合推进剂).
Theoretical analysis and experimental study of dynamic burning of solidpropellants have been carried out.A theoretical dynamic burning model of propellants hasbeen developed.The formula of dynamic burning rate is also derived.During the experi-mental study,it is found that in the course of propellant burning,the pressure variation ratecan have great effect on burning rate and the bigger the pressure variation rate is,the moreobvious the effect will be.Dynamic burnign rate is higher than static burning ratc by40.2%(for MDB)or 17.7%(for compesite propellant)at the most.
