  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. 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 ...

  4. External ballistics - Wikipedia

    en.wikipedia.org/wiki/External_ballistics

    Alternatively, manufacturer supplied ballistic trajectory data, or Doppler acquired velocity data can be fitted as well to calibrate the model. The Excel application then employs custom macroinstructions to calculate the trajectory variables of interest. A modified 4th order Runge–Kutta integration algorithm is used. Like Pejsa, Colonel ...

  5. 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).

  6. Trajectory - Wikipedia

    en.wikipedia.org/wiki/Trajectory

    A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. 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 ...

  7. Miller twist rule - Wikipedia

    en.wikipedia.org/wiki/Miller_twist_rule

    Miller twist rule is a mathematical formula derived by American physical chemist and historian of science Donald G. Miller (1927-2012) to determine the rate of twist to apply to a given bullet to provide optimum stability using a rifled barrel. [1]

  8. Muzzle energy - Wikipedia

    en.wikipedia.org/wiki/Muzzle_energy

    Pellet exiting muzzle, with formula for energy overlaid.. Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle of a firearm. Without consideration of factors such as aerodynamics and gravity for the sake of comparison, muzzle energy is used as a rough indication of the destructive potential of a given firearm or cartridge.
