Topic: Muzzle velocity


In the News (Fri 24 May 13)

  
  Muzzle velocity - Wikipedia, the free encyclopedia
A gun's muzzle velocity is the speed at which the projectile leaves the muzzle of the gun.
The latter velocity is close to the limit achievable with chemical propellants.
In conventional guns using gunpowder, muzzle velocity is determined by the quality (burn speed, expansion) and quantity of the propellant, the mass of the projectile, and the length of the barrel.

 Apparatus for measuring the muzzle velocity of a projectile fired from a weapon - Patent 4677376
The apparatus is simultaneously constructed as a muzzle brake and is suitable for measuring the muzzle velocity of sabot projectiles.
The propellant gases which efflux from the muzzle 54a of the weapon barrel 54 are deflected by the impact plates 40 and 41, whereby the apparatus as heretofore described also is effective as a muzzle brake, and thus, does not only serve for measuring the muzzle velocity of the fired projectiles.
However, the muzzle velocity of a projectile also can be measured by using a single measuring coil provided that the length of the projectile is known and there is then measured the time which expires between the entry of the projectile into and the exit of the projectile from such single measuring coil.

 FM 6-40 Chptr 4 Muzzle Velocity Management
However, muzzle velocities achieved in actual firing may differ from the standard muzzle velocities because of variations in the manufacture of the weapon and ammunition, wear in the weapon tube, projectile weight, propellant temperature, propellant lot efficiency, or a combination of these factors.
Muzzle velocity--the velocity achieved by a projectile as it leaves the muzzle of the weapon (measured in meters per second).
Muzzle velocity variation--the change in muzzle velocity of a weapon (expressed in meters per second) from the standard muzzle velocity.

The MG FF/M version fired a smaller round with a higher muzzle velocity, but it was still a short-range weapon, and its ballistic characteristics were very different from those of the 7.92mm machineguns installed on the same fighters (mainly Bf 109E).
One of the types of ammunition available was a 752g armour-piercing projectile with a muzzle velocity of 930m/s, and at a distance of 460m this penetrated 6cm of armour plate.
Because of the low muzzle velocity of the MK 108, it was not very suitable for fighter-vs-fighter combat, but in principle the Me 262 could outrun any enemy.

muzzle velocity difference, but the hotter lot was equally uniform when tested and well within the normal lot-to-lot tolerance range of about three percent.
Because we are limited to a fairly narrow muzzle velocity range and it sometimes takes more velocity change than desirable to change stability, we are left with the big job of making a new length of bullet, bullet molds (if not adjustable), and possibly swages to correct this problem.

 Muzzle velocity - WwiiolDocumentationProject   (Site not responding. Last check: 2007-10-21)
Muzzle velocity denotes the speed of a shot, round or shell as it exits the barrel of a gun or cannon.
The muzzle velocity, together with other factors such as weight and shape of the projectile, determines its ballistic trajectory and also its penetrating capacity.
Higher muzzle velocity generally means flatter trajectory and better penetration performance due to being able to deliver more kinetic energy on the target, but not always.

The chambers of the first Colt revolver were loaded with powder and bullets from the muzzle end, and each thamber had a nipple that required to be capped.
The muzzle velocity, with a charge of 16 grains of fl powder and a bullet of 150 grains of lead, is about 708 ft. per second, giving at 25 yards a penetration of about 5 in.
In the Nagant revolver, adopted by Russia, this disadvantage has been overcome by employing a long cartridge case which extends beyond the nose of the bullet and bridges the gap between barrel and cylinder as the cylinder is moved forward.

The muzzle velocity is a characteristic of the gun, but also depends on the weight of the projectile and the type of propellant in the cartridge case, so again may vary depending on the ammunition type.
Basically, it is a power-to-weight ratio: The kinetic energy at the muzzle (which is one half the projectile weight multiplied with the square of the muzzle velocity) multiplied by the rate of fire in rounds per second, and divided by the weight of the gun.
One of the types of ammunition available was a 752 g armour-piercing projectile with a muzzle velocity of 930 m/s, and at a distance of 460 m this penetrated 60 mm of armour plate.

In conventional guns using gunpowder muzzle velocity is determined by the of propellant the mass of the projectile and length of the barrel.
As the gun's charge is mostly burned before the projectile moved very far down the barrel adding to the barrel will not indefinitely increase muzzle velocity.
There is also a significant in not having to carry explosive propellant even the projectile internal charges may be due to the high velocity - the becomes a strictly kinetic weapon.
