Study of Ignition and Burning Pattern of Propellant from Various Rimfire Cartridges

The propellant is the complex organic compound. Basically it contains nitrocellulose and nitroglycerine. They are classified into two categories namely black powder and smokeless powder. All smokeless powders contain nitrocellulose however; powder contains nitroglycerine known as double base cordite. Propellant used in cartridges is made of variety of sizes, shapes, color and modification made on their surface. This propellant burns with flame having different nature and color, which depends on the various ingredients of propellant. In the present work, we describe the ignition and burning pattern of propellant in respect of their color and nature of flame on burning. For this purpose seven different types of rimfire cartridges are selected.
