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 ...
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 ...
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
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.
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.
Full service charge: the full amount of propellant intended for use in action at maximum range, for the usual shell. If a gun had e.g. a "heavy" and a "light" shell, there would be a separate charge associated with the heavy and light shells. Reduced service charge: for practice or firing star shells (which were lighter than the normal shell).
A blank is a firearm cartridge that, when fired, does not shoot a projectile like a bullet or pellet, but generates a muzzle flash and an explosive sound (muzzle report) like a normal gunshot would. Firearms may need to be modified to allow a blank to cycle the action, and the shooter experiences less recoil with a blank than with a live round.
The initial velocity (Vo) and real muzzle velocity (Vr) difference. During the first part of the intermediate ballistics period the real velocity of the projectile increases. It is caused by the propellant gases exiting the muzzle. For that reason the real maximum projectile velocity (Vmax) is higher than the real muzzle velocity (Vr).
