Agenda What is Artillery? Basics of Artillery Guns Basics of Artillery Projectile
What is Artillery?Artillery –Engines of War that operate by projection of munitions far beyondthe range of effect of personal weapons.Typically : Artillery is more advance version of RifleArtillery consist of GUN : Is a Weapon Used to throw a projectile at a very long distance. Projectile : Solid Projectile : It is made of Metal Hollow projectile : It is hollow to take explosives
Artillery GUN - Basics The caliber of the gun is determined by the diameter of the barrelThe length of the barrel is represented by CalibersThe barrel of the gun is usually rifled forcing the projectile to spin, stabilizing the projectileThe propellant forces in the barrel. 1. Horizontal force : Which takes the projectile away 2. Circumferential force : Which creates Spin action 3. Recoil : Due to above forces a Counter force of equal size is created
Classification of Guns – Based on RangeCannon •Barrel length of at least 20 calibers. •The cannons fire usually with a flatter trajectoryHowitzer •Barrel length between 12 - 20 calibers. •Higher maximum elevations than cannons •useful in forested, rough and hilly terrain.Mortar •The mortars have a barrel length under 12 calibers •They fire in high angles, elevations ranging usually from 40º to 80º. •The barrel is smooth, the projectiles have tail fins to stabilize the flight.
Classification of Guns – Based on Usage 1. Anti personal Guns (AP Guns) 2. Anti Tank Guns (AT Guns) 3. Recoilless Guns 4. Anti Aircraft Guns (AA Guns) 5. Tank Guns – Which are mounted of tanks 6. Missiles - Rocket technologyWe will try to further understand Anti Personal Gun Only
Anti Personal gun – Basic Structure Parts are classified in 3 structures 1. Basic Structure 2. Super structure 3. Telescope Basic Structure: Super Structure: Telescope: Carriage Ordnance For aiming Trail Breech Mechanism Spade Firing Mechanism Mounting Recoil System Clamps Traversing and elevating gears
Usage of PartsBasic Structure Usage Carriage : Gives support to Mount and ordnance Trail : Laying purpose Spade : Gun digging in Mud and Bunker Mounting & clamps: Gives support to ordnance Elevating/Traversing gear : Traversing/elevating purposesSuper Structure: Ordnance : Gives spin movement to projectile Breech Block : To give up and down movement to feed ammunition Firing Mechanism : To strike the base of ammunition Recoil System : Forward and backward movement of barrelTelescope:Fitted on mounting for aiming
Artillery projectile All artillery pieces use/fire ammunition that is called a shell SHELL PARTS: The cartridge case: which holds the propellant charge and the projectile. The projectile: which is the part of the shell that is propelled into the target The propellant charge: which propels the projectile. The fuse: which detonates the explosive charge (or filler) inside the projectile. The primer: which detonates the propellant charge
What effect Ammunition causeFragmentation EffectBlast Effect
Projectile fragmentationThe explosive filler blow upThe detonating wave converts the explosive filler to gasesExerts extremely high pressure on the inner surface of theprojectile.The projectile breaks apartThe shear and cleavage sends fragments/splinters flying withhigh velocity in (roughly) three separate fans..
Artillery projectile blast effect The different possible damage (or effect) pressure, splinter, shock, concussion and psychological. The blast effect depends on The shape, structure and the caliber of the projectile The kinetic energy of the projectile The blast of the explosive filler (causing a pressure wave) The splinters that fan out from the body of the projectile, The volume of sound of the blast
Kargil WAR – Artillery GUN About 250 artillery guns were used Terrain was mountainous and at high altitudes Bofors GUN was used to clear the infiltrators in the posts that were in theBofors FH-77B Field Howitzer Line of Sight
