Abstract
Analyzing the feasibility of a fin stabilized projectile for long range target shooting applications. This application is for the sports of competitive shooting. The two projectiles that have been compared are a standard long range target shooting projectile and a fin stabilized projectile. The fin stabilized projectile was designed to have the same weight and velocity as a standard longrange projectile. The standard projectile had a known ballistic coefficient and weight. The manufacturer of the projectile had published a formula for minimum spin requirements to stabilize a given projectile at a selected muzzle velocity. The forces involved in stabilizing the standard projectile were calculated and summed to give an energy input. Similar calculations were done for a fin stabilized projectile and the two were compared.
Next there was a comparison of the drag of the two projectiles. The ballistic coefficient for the standard projectile was given by the manufacturer and the ballistic coefficient of the fin stabilized projectile was calculated using the same formula as that of the standard projectile. The ballistic coefficients were then used to calculate the velocity loss over distance from the muzzle to 2000 meters. The results showed that the fin stabilized projectile had a much lower ballistic coefficient than the standard projectile. The fin stabilized projectile also retained its velocity over distance better than the standard projectile. The fin stabilized projectile retained 85% of its original velocity whereas the standard projectile retained 53% of its original velocity. This revealed that a fin stabilized projectile is a design that shows great potential for long range target shooting applications.
