ABSTRACT : |
Propellants burn along the local normal and the linear regression rate is called burn rate. In this paper, the burning rate was determined from the combustion photography (images) taken by high speed camera. These images were processed frame by frame by writing an algorithm in MATLAB, detecting the edges in the images of the frames. Image analysis was processed by edge detection method in MATLAB. Images of solid propellant combustion of three different proportions were taken for analysis. The results found to be satisfactory. The burning rate is obtained as the slope of the linear fit from MATLAB as shown in figure. Paper explains about the types of solid propellants, propellant ingredients and its formulation.
