Abstract

The radiation driven response function (R-q) for AP and HMX propellant wasobtained and compared with experimental results by using a simple alpha beta gamma flame model rather than with detailed chemistry. For an AP propellant, the profile of heat release was assumed by the experimental data. The calculated R-q shows a frequency shift of the peak amplitude to the higher frequency and a decrease in the maximum amplitude as radiation increases. In addition, it was found the increase in the total flux could enhance the mean burning rate <(<gamma>)over bar>(b) while the phase differences betweenthe radiation and resulting conduction could consequently reduce the fluctuation amplitude Delta gamma (b). Fortunately, this is the qualitative duplication of the behavior recently observed in the experiments of RDX propellants. For HMX, the response function R-q has been calculated and showed a quite good agreement with the experimental data. Even though the fairly goodagreement of R-q with experimental ones, the unsteady behavior of HMX was not reproduced as the radiation input increased. This is due to lack of thematerial properties of HMX or the physical understanding of HMX burning athigh pressure.
