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.
Accurizing. Ruger 10/22 carbines, before accurizing (top) and after (below). Externally visible changes are the target-style stock, the more vertical thumbhole grip, the free-floated bull barrel, and a muzzle brake. Accurizing is the process of improving the accuracy and precision of a gun (firearm or airgun).
Transitional ballistics is a complex field that involves a number of variables that are not fully understood; therefore, it is not an exact science. [6] When the bullet reaches the muzzle of the barrel, the escaping gases are still, in many cases, at hundreds of atmospheres of pressure. [3] Once the bullet exits the barrel, breaking the seal ...
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 ...
Spin stabilization. In aerospace engineering, spin stabilization is a method of stabilizing a satellite or launch vehicle by means of spin, i.e. rotation along the longitudinal axis. The concept originates from conservation of angular momentum as applied to ballistics, where the spin is commonly obtained by means of rifling.
There may also be further external ballistic effects which may in themselves be a function of the launch parameters of the shot. The components of gun jump are shown in Figure 5. Figure 5. The components of gun jump. When a gun is fired, the angle of the muzzle changes, and there is a transverse velocity component of the muzzle.
The Magnus effect is a phenomenon that occurs when a spinning object is moving through a fluid. A lift force acts on the spinning object and its path may be deflected in a manner not present when it is not spinning. The strength and direction of the Magnus effect is dependent on the speed and direction the of rotation of the object. [1]
Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration.
