Artillery can be used to fire nuclear warheads, as seen in this 1953 nuclear test. The projectile is the munition or "bullet" fired downrange. This may be an explosive device. Projectiles have traditionally been classified as "shot" or "shell", the former being solid and the latter having some form of "payload".
Heavy artillery pieces and naval artillery tend to use bagged charges and projectiles because the weight and size of the projectiles and propelling charges can be more than a gun crew can manage. Advantages include easier handling for large rounds, decreased metal usage, while range and velocity can be varied by using more or fewer propellant ...
The projectile carried 88 M42/M46 grenade-like dual purpose submunitions. The grenades are very similar, but M42 side wall is optimized for fragmentation characteristics while M46s have thicker walls strengthened to withstand additional setback loads in the last three aft layers of the projectile, where they are placed.
In projectile motion the most important force applied to the ‘projectile’ is the propelling force, in this case the propelling forces are the muscles that act upon the ball to make it move, and the stronger the force applied, the more propelling force, which means the projectile (the ball) will travel farther. See pitching, bowling.
Rocket assist is most effective with subsonic artillery projectiles. For supersonic long range artillery, where base drag dominates, base bleed is employed. Base bleed is a form of a gas generator that does not provide significant thrust, but rather fills the low-pressure area behind the projectile with gas, effectively reducing the base drag ...
Area denial artillery munition (ADAM) is a family of United States land mines and 155 mm artillery projectiles. The mines carried by these projectiles are the M67 long-duration anti-personnel mines and M72 short-duration anti-personnel landmines intended to maim or kill enemy combatants. The duration refers to the self-destruct time, which is ...
Indirect fire is aiming and firing a projectile without relying on a direct line of sight between the gun and its target, as in the case of direct fire. Aiming is performed by calculating azimuth and inclination, and may include correcting aim by observing the fall of shot and calculating new angles.
For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
