Transcript

  • 1. Mr. M. B. DANGE A8 -1202
  • 2. Agenda What is Artillery? Basics of Artillery Guns Basics of Artillery Projectile
  • 3. 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
  • 4. Artillery GUN - Basics The caliber of the gun is determined by the diameter of the barrelThe length of the barrel is represented by CalibersThe barrel of the gun is usually rifled  forcing the projectile to spin, stabilizing the projectileThe 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
  • 5. 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.
  • 6. 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
  • 7. 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
  • 8. 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
  • 9. 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
  • 10. What effect Ammunition causeFragmentation EffectBlast Effect
  • 11. Projectile fragmentationThe explosive filler blow upThe detonating wave converts the explosive filler to gasesExerts extremely high pressure on the inner surface of theprojectile.The projectile breaks apartThe shear and cleavage sends fragments/splinters flying withhigh velocity in (roughly) three separate fans..
  • 12. 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
  • 13. 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
  • 14.  BACKUP
  • 15. Indian Army – Key ArtilleryTOWED Artillery:  Indian Ordnance Factories 105 mm Light Field Gun  D-30 122 mm Towed Artillery Howitzer [2A18]  M-46 130 mm Towed Artillery Field Gun [M1954]  Haubits Bofors FH77B Towed Artillery HowitzerRocket Launchers:  BM-21 Grad 122mm Multi Barrel Rocket Launcher  BM-30 Smerch 9A52-2T 300mm Multi Barrel Rocket Launcher  Pinaka 214mm Multi Barrel Rocket Launcher
