2. Recoil operation - Wikipedia

   en.wikipedia.org/wiki/Recoil_operation

   Block diagram of short recoil operation cycle. See diagram key above. Ready to fire position. Bolt is locked to barrel, both are fully forward. Upon firing, bolt and barrel recoil backwards a short distance while locked together. Near the end of the barrel travel, the bolt and barrel unlock.

3. Hydraulic recoil mechanism - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_recoil_mechanism

   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 to ...

4. Gun laying - Wikipedia

   en.wikipedia.org/wiki/Gun_laying

   Gun laying. Gun laying is the process of aiming an artillery piece or turret, such as a gun, howitzer, or mortar, on land, at sea, or in air, against surface or aerial targets. It may be laying for either direct fire, where the gun is aimed directly at a target within the line-of-sight of the user, or by indirect fire, where the gun is not ...

5. Locked breech - Wikipedia

   en.wikipedia.org/wiki/Locked_breech

   Locked breech is the design of a breech-reloading firearm's action. This is important in understanding how a self-reloading firearm works. In the simplest terms, the locked breech is one way to slow down the opening of the breech of a self-reloading firearm when fired. The source of power for the movement is recoil. Blowback action.

6. Recoil - Wikipedia

   en.wikipedia.org/wiki/Recoil

   Recoil is explained by the law of conservation of momentum, and so it is easier to discuss it separately from energy. Momentum is simply mass multiplied by velocity. Velocity is speed in a particular direction (not just speed). In a very technical sense, speed is a scalar (mathematics): a magnitude; while velocity is a vector (physics ...

7. Recoilless rifle - Wikipedia

   en.wikipedia.org/wiki/Recoilless_rifle

   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 ...

8. Physics of firearms - Wikipedia

   en.wikipedia.org/wiki/Physics_of_firearms

   Physics of firearms. From the viewpoint of physics (dynamics, to be exact), a firearm, as for most weapons, is a system for delivering maximum destructive energy to the target with minimum delivery of energy on the shooter. [citation needed] The momentum delivered to the target, however, cannot be any more than that (due to recoil) on the shooter.

9. Internal ballistics - Wikipedia

   en.wikipedia.org/wiki/Internal_ballistics

   Internal ballistics (also interior ballistics), a subfield of ballistics, is the study of the propulsion of a projectile. In guns, internal ballistics covers the time from the propellant 's ignition until the projectile exits the gun barrel. [1] The study of internal ballistics is important to designers and users of firearms of all types, from ...
