External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field.
External ballistics is the part of the science of ballistics that deals with the behaviour of a non-powered projectile in flight. External ballistics is frequently associated with firearms , and deals with the unpowered free-flight phase of the bullet after it exits the gun barrel and before it hits the target, so it lies between transitional ...
As an example, a bullet with a mass of 160 grains (10.4 g) and a diameter of 0.264 in (6.7 mm), has a sectional density (SD) of: 4·(160 gr/7000) / (π·0.264 in 2 ) = 0.418 lb m /in 2 As another example, the M107 projectile mentioned above with a mass of 95.2 pounds (43.2 kg) and having a body diameter of 6.0909 inches (154.71 mm) has a ...
Often broken down into internal ballistics, transitional ballistics, external ballistics and terminal ballistics. Battle rifle: A service rifle capable of semi-automatic or fully automatic fire of a full-power rifle cartridge. Bayonet lug: An attachment point at the muzzle end of a long gun for a bayonet.
Ballistics (gr. ba'llein, "throw") is the science that deals with the motion, behavior, and effects of projectiles, especially bullets, aerial bombs, rockets, or the like; the science or art of designing and hurling projectiles so as to achieve a desired performance.
The projectile's motion in flight is known as its external ballistics, and its behavior upon impacting an object is known as its terminal ballistics. A bullet can be made of virtually anything (see below ), but lead is the traditional material of choice because of its high density, malleability , ductility , and low cost of production .
Shooter’s height questioned – Defence expert Mike Sutton testified that the ballistics evidence suggests the shooter is 5’2” tall. Murdaugh is 6’4”. Murdaugh is 6’4”.
The Coriolis force is important in external ballistics for calculating the trajectories of very long-range artillery shells. The most famous historical example was the Paris gun, used by the Germans during World War I to bombard Paris from a range of about 120 km (75 mi). The Coriolis force minutely changes the trajectory of a bullet, affecting ...
