Internal ballistics (also interior ballistics), ... The temperature depends on the energy released and the heat loss to the sides of the barrel and chamber.
Environmental conditions will both affect consistency (e.g. variable wind conditions down range), or accuracy (e.g. change in temperature and hence air density which affects the external trajectory). In some cases, these are accountable and could possibly be corrected in the fire control system.
QuickLOAD is an internal ballistics predictor computer program for ... It can predict the effect of changes in ambient temperature, bullet seating depth, and barrel ...
High temperatures tend to erode the barrel at the throat, preventing the bullet from entering the rifling cleanly. ... The internal ballistics of a given cartridge ...
[4]: 125 The motion and behavior characteristics of projectiles while under the influence of the gases produced by the propellant is known as internal ballistics. [ 13 ] Due to the relatively short distance a gun barrel can offer, the sealed acceleration time is very limited and only a small proportion of the total energy generated by the ...
Internal ballistics: A subfield of ballistics, that is the study of a projectile's behavior from the time its propellant's igniter is initiated until it exits the gun barrel. The study of internal ballistics is important to designers and users of firearms of all types, from small-bore Olympic rifles and pistols , to high-tech artillery .
In 2006, the U.S. Department of Agriculture lowered the safe internal cooking temperature for the whole turkey — breast, legs, thighs, and wings — and all other poultry.
This test is performed under normal conditions at 21 °C (70 °F), but also by simulating cold polar −54 °C (−65 °F) or hot desert 52 °C (126 °F) conditions using special cooling equipment and ovens to cool or heat the ammunition under test to the appropriate levels of humidity and temperatures required.
