United We Prepare PRINCIPLE OF OPS  PRINCIPLE OF SHOT GUN - CATERS FOR AIMING ERRORS.  PARENT BOMB CONTAINS NUMBER OF SUB- MUNITIONS.  ON RELEASE FROM AC - PARENT BOMB IS RETARDED - EITHER RETARDING FINS OR PARACHUTE.  AFTER ENSURING THAT THE BOMB HAS BEEN SUFFICIENTLY RETARDED - THE SKIN / COVER OF THE PARENT BOMB IS EXTRACTED / PEELED OFF.

United We Prepare PRINCIPLE OF OPS  AFTER ENSURING THAT THE SKIN IS PEELED OFF - SUB-MUNITIONS ARE EXTRACTED.  EACH SUB-MUNITION AFTER EXTRACTION IS SEPARATELY RETARDED.  EACH SUB-MUNITION FUNCTIONS INDEPENDENTLY AFTER HITTING THE TARGET.  TYPE OF WARHEAD IN THE SUB-MUNITION - ANTIPERSONNEL OR ANTI-TANK OR RUNWAY PENETRATION.

United We Prepare NOSE SECTION. ARMING VANE SAFETY ARMING & FUNCTIONING UNIT BREECH & VALVE ASSEMBLY LEAD ELECTRICAL FUZE ARMING AIR ARMING VANE SAFU INFLATABLE BAG

United We Prepare AIR ARMING VANE CENTRE SECTION. GAS TUBE GAS DISTRIBUTION BLOCKS INFLATABLE BAGS BOMBLETS TAIL SECTION FINS FOR RETARDING THE BOMB SAFU INFLATABLE BAG

United We Prepare SAFETY ARMING AND FUNCTIONING UNIT (SAFU) LOCATED IN THE BOMB NOSE. INITIATES FIRING SEQUENCE WHICH RELEASES THE BOMB SKIN AND EJECTS BOMBLETS. FOUR TIME DELAY SETTINGS-.08,.8,.94, 1.13 sec. CONDITIONS TO BE SATISFIED. LIVE RELEASE HAS BEEN SELECTED BY PARENT AC. AFTER SPECIFIED DELAY SETTING. ARMING VANE ROTATES AT SPECIFIED RPM.

United We Prepare SAFU - COMPONENTS  GAS MOTOR ASSY- SEALED X – RELEASES SAFETY DEVICE  CLUTCH AND DRUM ASSY – COUPLED TO ARMING VANE  STRIKER ASSY  TIMER ASSY – DELAY FIRING OF PRIMARY CARTRIDGE  TRIGGER ASSY

United We Prepare GAS SYSTEM  THROUGH TWO CARTRIDGES LOCATED IN BREECH AND VALVE ASSY  BREECH AND VALVE ASSY  ROUTES GAS FLOW FROM PRIMARY CARTRIDGE – UNLATCHING/LIFT OF SKIN  ROUTES GAS FLOW FROM SECONDARY CARTRIDGE TO EJECT BOMBLETS  GAS DISTRIBUTION BLOCKS  GAS TUBE – MOVES REARWARDS AND CONVEYS GASES FROM SEC CARTRIDGE TO GAS DISTRIBUTION BLOCKS

United We Prepare CENTRE SECTION  BOMBLETS  147 BOMBLETS ARRANGED IN 7 BAYS  EACH BAY HAVING 7 SECTIONS  EACH SECTION HAVING THREE BOMBLETS  EACH SECTION HAS ONE INFLATABLE BAG – 49 BAGS IN TOTAL  VEL OF GASES AND INFLATION RATE OF BAGS IS CONTROLLED  2,4,6 SECTIONS HAVE HIGH GAS FLOW – EJECTED FIRST  1,3,5,7 SECTIONS HAVE LOW GAS FLOW – EJECTED LATE

United We Prepare 1. AFTER RELEASE, STABILISING FINS EXTEND AND THE BOMB FOLLOWS A NORMAL BALLISTIC TRAJECTORY. 2. AFTER A SELECTED TIME DELAY THE OUTER CASING IS SPLIT INTO TWO BY GAS PRESSURE FROM A PRIMARY CARTRIDGE.

United We Prepare 3. ONCE THE BODY CASE HAS OPENED THE MAIN GAS CARTRIDGE IS ACTIVATED AND ITS PRESSURE EJECTS THE BOMBLETS.

CLUSTER BOMBLET

United We Prepare FUNCTIONING OF BOMBLET

United We Prepare BOMBLET EJECTION VELOCITY IS VARIED BETWEEN BAYS TO ENSURE EVEN GROUND COVER. EACH BOMBLET IS ARMED AFTER A SHORT PERIOD OF FLIGHT AND ON IMPACT THE SHAPED CHARGE PENETRATES THE ARMOUR – 25 CM PENETRATION. IN ADDITION TO ITS ANTI-ARMOUR CAPABILITY EACH BOMBLET CASING DISINTEGRATES INTO 2000(1850 MT/S) FRAGMENTS WHICH ARE EFFECTIVE AGAINST NON-ARMOURED TARGETS AND PERSONNEL. PIEZO ELECTRIC FUSE – FUSE ARMED ONLY WHEN TAIL IS DEPLOYED – FIVE ROTATIONS OPERATION

United We Prepare BME 330 CLUSTER BOMB  MANUFACTERED BY EXPAL COMPANY OF SPAIN.  MIG-23,MIG-27 AND JAGUAR AIRCRAFT.  RELEASE POSSIBLE AT 30 MTS  WEIGHT - 320kgs  NUMBER OF BOMBLET  WT. OF EACH BOMBLET kgs  BOMB EFFICIENCY 95%  BOMBLET EFFICIENCY 80%  20 % BOMBLETS MAY/MAY NOT WORK

United We Prepare NOSE CONTAINER  IT CONSTITUTES THE FRONTAL END OF THE CYLINDRICAL SKIN AND HOUSES THE TWIN FUZE SYSTEM AND ELECTRONIC UNIT  THIS ELECTRONIC UNIT SUPPLIES ELECTRICAL POWER THROUGH FUZE TO DE-SKINNING OF BODY AND TO THE PYROCARTRIDGE FOR SCATTERING OF BOMBLETS. MAIN BODY  MAIN BODY HOUSES THE CLUSTER FRAME WHERE BOMBLETS ARE STORED IN NINE LAYERS EACH LAYER CONTAINS TWENTY BOMBLETS.IT ALSO CONTAINS THE DE-SKINNING SYSTEM AND THE SCATTERING SYSTEM FOR BOMBLETS DISPERSION. TAIL UNIT  STABILISES THE BOMB AFTER RELEASE.IT HOUSES A PARACHUTE ASSEMBLY HELD TO THE BOMB WITH THE HELP OF HOLDING DEVICE.

United We Prepare BOMBLETS  180 BOMBLETS.  TWO TYPES - ANTI PERSONNEL AND ANTI ARMOUR.  MIX - FACTORY SET AND CANNOT BE REARRANGED.  SEPARATE PARACHUTE PROVIDED FOR EACH BOMBLET.  THREE TYPES OF PARACHUTES USED HAVING VARYING CANOPY AREA - SMALL, MEDIUM AND LARGE.  FIRST THREE LAYERS HAVE SMALL PCHUTES  LAST THREE LAYERS HAVE LARGE PCHUTES  INDIVIDUAL FUZE.
