摘要
本文叙述了由112mm发动机估算880mm发动机药柱燃速的试验研究.经统计分析,给出了大、小发动机药柱燃速之间的三个关系式,以及相应的估算误差.采用有效燃速可使估算误差t·S_y/(?)(%)减小至1.5%左右.
An experimental investigation on the estimation of grain bu-rnin rate for 880mm solid motor in terms of that of 112mm motor is described. Based on statistical analyes, three formulas which correlate the grain burning rates of large and small solid motor, and their corresponding errors are given. By using the definition of effective burning rates, the error t-Sy/y% can be reduced to->1.5%.
