From a performance standpoint, they should burn inward at the burning surface in a consistent and predictable manner that is not unduly sensitive to pressure or bulk temperature at a rate typically in the range of 0.2 20 cm (0.08 7.8 inches)per second.
By comparing the difference of characteristics between the burned and unburned zone, the result shows that coke deposition occurs under the burning surface, where the coke deposition zone is.
Simultaneously, the emergence of the thermocouple from the burning surface was determined with a video camera.
Temperature profiles near the burning surface were measured with a thermocouple embedded in the specimen.
The burning surface temperature of PMMA was measured for both end-burning and sandwich-burning experimental devices.
Thus, the burning surface of AN did not regress simultaneously with the burning surface of the AP-filled region, the matrix of AP, and HTPB.
The burning surface temperature obtained in the present study was found to be almost independent of the regression rate.
The conductive heat flux averaged over the burning surface was estimated to be approximately 13.2 kW/m2.
The burning rate of rocket motors running with solid propellant is called flame regression, which occurs with the ignition in the fuel grain perpendicular to the burning surface.
