[recoil_calculator]

  • Create recoil energy calculator with JavaScript.
  • User can input number for bullet mass, muzzle velocity, powder mass, powder velocity, and gun mass.
  • User can input number directory into input form or input number into input form by using drop-down menu to select number.
  • Users can select metric or imperial units by using the drop-down menu.
  • when user press calculate button, this calculator output both result of recoil energy and gun velocity.
  • Use this formula to calculate when unit is metric;
  • “Recoil velocity = (bullet mass * muzzle velocity) + (powder mass * powder velocity)/ gun mass * 1000”
  • “Recoil energy = 0.5 * gun mass * recoil velocity * recoil velocity”
  • Use this formula to calculate when unit is imperial;
  • “Recoil velocity = (bullet mass * muzzle velocity) + (powder mass * powder velocity)/ gun mass * 7000”
  • “Recoil energy = gun mass * gun velocity * gun velocity / 2 * 32.1739”
  • Create JavaScript section only.
  • Code should be simple and as short as possible.
  • Do not create HTML and CSS sections.
  • Do not use unit conversion.

This form is going to use in this calculator;

メートル

Momentum long from:

反動速度 = (弾頭重量 x 銃口初速) + (装薬重量 x 装薬速度) / 銃の重量 x 1000.

リコイルエナジー = 0.5 x 銃の重量 x 反動速度の二乗

recoil velocity = (bullet mass * muzzle velocity) + (powder mass * powder velocity)/ gun mass * 1000

recoil energy = 0.5 * gun mass * recoil velocity * recoil velocity

Firearm: Mauser 98 chambered in 7 x 57 mm Mauser weighing 4.54 kilograms.
Projectile: spitzer type bullet weighing 9.1 grams with a muzzle velocity of 823 meters per second.
Powder charge: single base nitrocellulose weighing 2.75 grams with a powder charge velocity of 1585 meters per second.
2.61 m/s = (9.1 x 823) + (2.75 x 1585) / 4.54 x 1000.
Then, plug the now known Gun velocity of 2.61 meters per second into the translational kinetic energy formula:

15.43 J = 0.5 x 4.54 x 2.612.

Momentum short form:

リコイルエナジー = 0.5 x {[ (弾頭重量 x 銃口初速) + (装薬重量 x 装薬速度) / 1000]2} / 銃の重量

15.43 J = 0.5 x {[ (9.1 x 823) + (2.75 x 1585) / 1000]2} / 4.54.

ヤードポンド

Momentum long from:

Gun velocity = (bullet mass x bullet velocity) + (powder charge mass x powder charge velocity) / Gun mass x 7000.

Gun velocity = (bullet mass * muzzle velocity) + (powder mass * powder velocity)/ gun mass * 7000

Then, plug the now known Gun velocity into the translational kinetic energy formula:

Recoil energy = Gun mass x Gun velocity2 / 2 x dimensional constant.

Recoil energy = gun mass * gun velocity * gun velocity / 2 * 32.1739

Example:Firearm: Mauser 98 chambered in 7 x 57 mm Mauser weighing 10 pounds.Projectile: spitzer type bullet weighing 140 grains with a muzzle velocity of 2700 feet per second.Powder charge: single base nitrocellulose weighing 42.5 grains with a powder charge velocity of 5200 feet per second.

8.557 ft/s = (140 x 2700) + (42.5 x 5200) / 10 x 7000.

Then, plug the now known Gun velocity of 8.557 feet per second into the translational kinetic energy formula:

11.38 ft-lbf = 10 x 8.5572/ 2 x 32.163.


Momentum short form:

Recoil energy = {[ (bullet mass x bullet velocity) + (powder charge mass x powder charge velocity) / 7000]2} / Gun mass x 2 x dimensional constant.

11.38 ft-lbf = {[ (140 x 2700) + (42.5 x 5200) / 7000]2} / 10 x 2 x 32.163.
