A single based fuel/propellant has nitrocellulose as its chief explosives ingredient. Stabilizers and other additives are used to control the chemical stability and enhance its properties. Double-based fuel/propellant Double-based fuel/propellants consist of nitrocellulose with nitroglycerin or other liquid organic nitrate explosives added.
In practice it is defined as the explosive's ability to accomplish what is intended in the way of energy delivery (i.e., fragment projection, air blast, high-velocity jet, underwater shock and bubble energy, etc.). Explosive power or performance is evaluated by a tailored series of tests to assess the material for its intended use.
Series 5 tests are used to determine if an article can be assigned to HD1.5 'Very Insensitive Explosive'; series 6 tests are used to determine the classification of an article within Hazard Divisions 1.1, 1.2, 1.3, or 1.4; and series 7 tests are used to determine if an article can be assigned to HD 1.6 as an article containing predominantly ...
Preparing 105 mm M119 howitzer ammunition: powder propellant, cartridge, and shell with fuze. The components of ammunition intended for rifles and munitions may be divided into these categories: fuze or primer; explosive materials and propellants; projectiles of all kinds; cartridge casing
Gunpowder is a low explosive: it does not detonate, but rather deflagrates (burns quickly). This is an advantage in a propellant device, where one does not desire a shock that would shatter the gun and potentially harm the operator; however, it is a drawback when an explosion is desired.
During the 1930s, triple-base propellants containing nitrocellulose, nitroglycerin or diethylene glycol dinitrate, and a substantial quantity of nitroguanidine (detonation velocity 8,200 m/s (26,900 ft/s), RE factor 0.95) as explosive propellant ingredients were commercialized.
Black powder was the first explosive ever invented, and was the primary propellant used firearms around the world for many centuries. However, in modern times, smokeless powder has largely replaced black powder as the most common firearm propellant.
Explosive rounds as small as 12.7 x 82 mm and 13 x 64 mm have been used on aircraft and armoured vehicles, but their small explosive yields have led some nations to limit their explosive rounds to 20mm (.78 in) or larger. International Law precludes the use of explosive ammunition for use against individual persons, but not against vehicles and ...
