An Analytical Model for Predicting the Daily Temperature Cycle of Container Stored Ordnance.

摘要

The heat transfer characteristics of a container stored rocket motor have been investigated using analytical and experimental techniques. Comparison between analytically predicted and experimentally determined values of temperature are within the estimated experimental uncertainty of plus or minus 3F. The results of the analytical solution may be used to predict maximum and minimum temperatures,thermal time lags,and temperature gradients throughout the rocket motor. For convenience,maximum temperature and time lag information is presented in nomograph form as a function of three parameters:normalized radial location,normalized frequency,and normalized gap conductance. These three parameters control the temperature behavior of the motor. It is proposed that the nomographs will be a useful tool for thermally optimizing future container designs. (Author)
