A heavier gun, that is a gun with more mass, will manifest lower recoil kinetic energy, and, generally, result in a lessened perception of recoil. Therefore, although determining the recoiling energy that must be dissipated through a counter-recoiling force is arrived at by conservation of momentum, kinetic energy of recoil is what is actually ...
In non-recoil-operated firearms, it is generally the entire firearm that recoils. However, in recoil-operated firearms, only a portion of the firearm recoils while inertia holds another portion motionless relative to a mass such as the ground, a ship's gun mount, or a human holding the firearm. The moving and the motionless masses are coupled ...
The usual recoil system in modern quick-firing guns is the hydro-pneumatic recoil system. In this system, the barrel is mounted on rails on which it can recoil to the rear, and the recoil is taken up by a cylinder which is similar in operation to an automotive gas-charged shock absorber , and is commonly visible as a cylinder mounted parallel ...
An M40 recoilless rifle on its M79 "wheelbarrow" tripod Diagram of the operation of a recoilless rifle using a vented case. A recoilless rifle (), recoilless launcher (), or simply recoilless gun, sometimes abbreviated to "RR" or "RCL" (for ReCoilLess) [1] is a type of lightweight artillery system or man-portable launcher that is designed to eject some form of countermass such as propellant ...
The French Chauchat, German MG 34 and MG 42 machine guns, the British Vickers machine gun, and some other recoil operated firearms use a gas trap style mechanism to provide additional energy to "boost" the energy provided by recoil. This "boost" provides higher rates of fire and/or more reliable operation.
According to Newtonian mechanics, if the gun and shooter are at rest initially, the force on the bullet will be equal to that on the gun-shooter. This is due to Newton's third law of motion (For every action, there is an equal and opposite reaction). Consider a system where the gun and shooter have a combined mass m g and the bullet has a mass m b.
Locked recoil systems rely on timing to allow safe operation. A very heavy bolt mechanism can be used (such as in sub-machineguns) to slow the rate of movement and reduce the rate of fire. [5] This is not adequate with higher velocity and higher energy cartridges. Rifles and most handguns use locked breech designs to control recoil safely.
The original use of the recoil booster was to provide additional energy to move the large barrel/bolt mass on recoil operated machine guns. [7] At the start of WWI the primary German machine gun was the Maxim-based MG 08, a water-cooled heavy machine gun equipped with a blank firing adapter but not a muzzle booster.
