| Abstract: | 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%. |
