  2. Ballistic coefficient - Wikipedia

    en.wikipedia.org/wiki/Ballistic_coefficient

    The formula for calculating the ballistic coefficient for small and large arms projectiles only is as follows: = [2] where: C b,projectile, ballistic coefficient as used in point mass trajectory from the Siacci method (less than 20 degrees).

  3. External ballistics - Wikipedia

    en.wikipedia.org/wiki/External_ballistics

    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.

  4. Projectile motion - Wikipedia

    en.wikipedia.org/wiki/Projectile_motion

    Lofted trajectories of North Korean ballistic missiles Hwasong-14, Hwasong-15 and Hwasong-17. A special case of a ballistic trajectory for a rocket is a lofted trajectory, a trajectory with an apogee greater than the minimum-energy trajectory to the same range. In other words, the rocket travels higher and by doing so it uses more energy to get ...

  5. Ballistics - Wikipedia

    en.wikipedia.org/wiki/Ballistics

    A ballistic missile is a missile that is guided only during the relatively brief initial phase of powered flight, with the trajectory subsequently governed by the laws of classical mechanics, in contrast to (for example) a cruise missile, which is aerodynamically guided in powered flight like a fixed-wing aircraft.

  6. Circular error probable - Wikipedia

    en.wikipedia.org/wiki/Circular_error_probable

    Circular bivariate normal distribution 20 hits distribution example The original concept of CEP was based on a circular bivariate normal distribution (CBN) with CEP as a parameter of the CBN just as μ and σ are parameters of the normal distribution .

  7. Rifleman's rule - Wikipedia

    en.wikipedia.org/wiki/Rifleman's_rule

    One can calculate using standard Newtonian dynamics as follows (for more details on this topic, see Trajectory). Two equations can be set up that describe the bullet's flight in a vacuum, (presented for computational simplicity compared to solving equations describing trajectories in an atmosphere).

  8. Trajectory - Wikipedia

    en.wikipedia.org/wiki/Trajectory

    In classical mechanics, a trajectory is defined by Hamiltonian mechanics via canonical coordinates; hence, a complete trajectory is defined by position and momentum, simultaneously. The mass might be a projectile or a satellite. [1] For example, it can be an orbit — the path of a planet, asteroid, or comet as it travels around a central mass.

  9. Sectional density - Wikipedia

    en.wikipedia.org/wiki/Sectional_density

    Sectional density has the same (implied) units as the ballistic coefficient. Within terminal ballistics, the sectional density of a projectile is one of the determining factors for projectile penetration. The interaction between projectile (fragments) and target media is however a complex subject.
