Burning time propellant

Fig. 7.8 shows the temperature profiles [temperature (K) versus burning time (s)] in the combustion waves of this propellant at 0.0355 MPa and at 0.0862 MPa. The temperature is seen to increase relatively smoothly in the condensed phase, but then increases with large fluctuations in the gas phase at both pressures. However, the rate of temperature increase is clearly much higher at 0.0862 MPa than at 0.0355 MPa.
