What is the ballistic coefficient?
The projectile ballistic coefficient is a measurement of its resistance to pulling when air is burned. Any shot or missile fired from a weapon will travel at a given distance based on several factors. The weight of the projectile, the ability to overcome its shape, which is called a shape factor, and air density are factors.
Understanding the behavior of the burned bullet is an important part of weapons design. The amount of powder used in the cassette accelerates the bullet to a certain speed when it leaves the barrel. At this point, gravity and campaign cooperate and pull out a bullet towards the ground and slowing. The wind also affects the path of bullets or trajectories by moving it in different directions when the bullet travels down to the goal.
The shape of the bullet or any projectile up to the large rocket is designed to minimize the campaign by having the shape of aerodynamic or lowering the campaign. Ballistic calculations use the measured evaluation form factor that represents the shape of the bullet. The shape factor calculations use the meentifiesNo coefficient of campaign divided by value for standard reference shape of industry.
After determining the form factor, the ballistic coefficient may be determined as a mathematical equation. The weight of the missiles, its shape factor and the bullet diameter are used in the calculation. The ballistic coefficient can vary very much over or below one for different bullets, but for the standard industrial projectile, one coefficient is assumed as a link. Many tests have been carried out since the 1970s to the 30th century to the purpose of developing ballistic information used as industrial standards for projectile testing.
Ball manufacturers publish data from the ballistic coefficient for their ammunition. Many sports shooters and hunters use bullets with higher coefficients because they theoretically provide better results. A higher coefficient will usually lead to bullets that travel with a flat trajectory or on the way above the ground and arein less sensitive to the effects of wind and air.
Posted data coefficient can be used for comparison, but there may be some differences. Changes in projectiles can cause differences in the weight or shape of the bullet. These differences can lead to actual performance that is less than published data. Although these differences may be slight, they may be important for precise shooters or shoot over more distances.
The data of the ballistic coefficient is also used for the development of a spacecraft since the 1950s. The behavior of a cosmic vehicle, such as capsule, will depend on having a very low coefficient or a large move that allows him to slow in the atmosphere to gently land. On the other hand, the ballistic missile must travel very quickly through an atmosphere with a small weather or air campaign, so it is tomus to have a very high coefficient.
