1 New French IM GP Bombs Development update Laurent Delrieu (DGA), Sébastien Régnaut (SAMP), Bruno Nouguez (Eurenco)

2 New French IM GP Bombs Background Objectives Technology Demonstrator Program Way Ahead DGA 16/05/2012 Diapositive N 2 / 22

3 Background 500 lb bombs in French Forces Mk 82 BLU 111 CBEMS 250 DGA 16/05/2012 Diapositive N 3 / 22

4 Background : Mk 82 Use General Purpose Bomb Armée de l air Description Similar to US BLU-111/B PBXN-109 irdx Manufacturer SAMP Eurenco IM Signature (MSIAC) FCO SCO BI FI SR IV/V IV/V V V I DGA 16/05/2012 Diapositive N 4 / 22

5 Use Background : BLU 111 General Purpose Bomb Marine Nationale Description Similar to US BLU-111A/B Thick Thermal Coating (FM26) PBXN-109 irdx Manufacturer SAMP Eurenco IM Signature (MSIAC) FCO SCO BI FI SR IV/V IV/V V V I DGA 16/05/2012 Diapositive N 5 / 22

7 Objectives for new GP bombs TDP Insensitive General Purpose Bomb (IM-B) Insensitive Low Collateral Damage Bomb (ILCD-B) General Purpose Bomb (GP-B) Bomb Mk-82 shape Insensitive CBEMS 250 Type III for SR Low collateral Damage Lower risk distances compared to Mk 82 General Purpose Mk-82 Lethality DGA 16/05/2012 Diapositive N 7 / 22

8 Objectives : Insensitive Sympathetic Reaction No propagation of detonation Reaction Type III Fast Cook Off No reaction for several minutes Reaction limited to combustion Heavy Fragment Impact No explosion when subjected to an impact of an Heavy Fragment DGA 16/05/2012 Diapositive N 8 / 22

9 Objectives : Bomb Compatibility with different interfaces Mk-82 outline : no thick thermal protection Fuzes : FBM21, FMU-139, FMU-143 Ejectors : TG480, Kits : AASM, Paveway DGA 16/05/2012 Diapositive N 9 / 22

11 TDP : Major Parts Venting Embedded booster Thin Thermal protection Liner Explosive DGA 16/05/2012 Diapositive N 11 / 22

12 TDP : Venting Prevent violent reaction for Sympathetic Reaction Slow Cook Off Light / Heavy Fragment Impact No reduction of reaction time for Fast Cook Off Principle Safety cut-out Pressure breaking Withstand environment DGA 16/05/2012 Diapositive N 12 / 22

13 TDP : Thermal Protection Test on intumescent coating with ENSCL (France) Evaluation of thermal coating, common and home-made intumescent coating Coated steel sample FAST COOK OFF (GAS OVEN) TEMPERATURE INCREASE AND FLUX COMPLIANT WITH STANAG 4240 INDIRECT FIRE (RADIATOR) DGA 16/05/2012 Diapositive N 13 / 22

14 TDP : Thermal Protection Common intumescent coating (layer < 1 mm) Less efficient than FM26 (15% less) Thin layer No burning European supply Home-made intumescent coating (layer < 1 mm) As efficient as FM26 Thin layer No burning European supply DGA 16/05/2012 Diapositive N 14 / 22

15 TDP : Explosives GP-B IM-B ILCD-B Main Filling B2258B B2268A B2274A Main Ingredients RDX/AP/Al/HTPB RDX/NTO/Al/HTPB RDX/Al/HTPB Embedded Booster / B2273A B2273A Main Ingredients / HMX/HTPB HMX/HTPB DGA 16/05/2012 Diapositive N 15 / 22

16 TDP : Liner and Booster Boostering reliability Fragment shapes and velocities identification Overall view - Velocity screen plates -Water bottle «frag catcher» - Overpressure measurement LDTU Large Diameter Testing Unit Post test view DGA 16/05/2012 Diapositive N 16 / 22

17 TDP : Liner and Booster Liners on production line DGA 16/05/2012 Diapositive N 17 / 22

18 TDP : Sympathetic Reaction Trials of IM-B 4 live IM-Bombs REACTION TYPE III Before test After test (and reconstruction) DGA 16/05/2012 Diapositive N 18 / 22

19 TDP : Arena tests IM-B (04/2012) & ILCD-B (05/2012) DGA 16/05/2012 Diapositive N 19 / 22

20 TDP : Delivery of demonstrators to DGA ILCD-B IM-B before loading DGA 16/05/2012 Diapositive N 20 / 22

21 Way Ahead IM test on IM-B Fast Cook Off Slow Cook Off Heavy Fragment Impact Arena test for ILCD-B DGA 16/05/2012 Diapositive N 21 / 22
