  2. M829 - Wikipedia

    en.wikipedia.org/wiki/M829

    The propulsion system uses an obturating case base with a semi-combustible cartridge wall. It has a total weight of 41.1 lb (18.6 kg) and a 627 mm (24.7 in) DU penetrator with a 27 mm (1.1 in) rod diameter, [2] which reaches a muzzle velocity of 1,670 meters per second (5,500 ft/s) using 8.1 kg (18 lb) of JA-2 propellant. Its maximum effective ...

  3. Sectional density - Wikipedia

    en.wikipedia.org/wiki/Sectional_density

    SD kg/cm 2 is the sectional density in kilograms per square centimeter; m g is the mass of the projectile in grams; d cm is the diameter of the projectile in centimeters; For example, an M107 projectile with a mass of 43.2 kg and having a body diameter of 154.71 millimetres (15.471 cm) has a sectional density of: 4 · 43.2 / (π·154.71 2) = 0. ...

    P: Momentum, in pound (force) (lbf) times seconds. [1] A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters. [2] Chg: Propellant charge, in grains; Dia: Bullet diameter, in inches

  6. Ballistic coefficient - Wikipedia

    en.wikipedia.org/wiki/Ballistic_coefficient

    Sporting bullets, with a calibre d ranging from 4.4 to 12.7 millimetres (0.172 to 0.50 in), have C b in the range 0.12 lb/in 2 to slightly over 1.00 lb/in 2 (84 kg/m 2 to 703 kg/m 2). Those bullets with the higher BCs are the most aerodynamic, and those with low BCs are the least.

  7. Thrust-to-weight ratio - Wikipedia

    en.wikipedia.org/wiki/Thrust-to-weight_ratio

    The weight (N) is calculated by multiplying the mass in kilograms (kg) by the acceleration due to gravity (m/s 2). The thrust can also be measured in pound-force (lbf), provided the weight is measured in pounds (lb). Division using these two values still gives the numerically correct (dimensionless) thrust-to-weight ratio.

  8. Kinetic energy penetrator - Wikipedia

    en.wikipedia.org/wiki/Kinetic_energy_penetrator

    The principle of the kinetic energy penetrator is that it uses its kinetic energy, which is a function of its mass and velocity, to force its way through armor. If the armor is defeated, the heat and spalling (particle spray) generated by the penetrator going through the armor, and the pressure wave that develops, ideally destroys the target.
