120 mm (Split Ring Ans Flake)

Description

These increments charge are fired by all 120mm mortar. There are kinds of double-base propellants containing NC, NG, plasticizer and stabilizer. Packing Split Ring: It is charged in Viscose rayon ring shape bag, and each set is packed inside PE bags. Packing flake: It is charged in horseshoe celluloid and each set is packed inside PE bags. Storage: Should be stored in -10 up to +30°C Shelf life: 15 years (min) TECHNICAL SPECIFICATIONSFormSplit ringFlakeDimension (mm)-5 × 5Inner Diameter(mm)55 ± 1-Outer Diameter (mm)105 ± 1-Mean web thickness (white bag charge) (mm)0.48 – 0.540.5 – 0.6Mean web thickness (red bag charge) (mm)0.17 – 0.230.27 – 0.33Moisture (%)< 0.5< 0.5Heat of explosion (cal/gr)1250 ± 201250 ± 20Stability at 120°C(min)≥ 40≥ 40  BALLISTIC SPECIFICATIONSForm120mm120mm LRTotal charge (gr)~360 (ch 9)~420 (ch 9)Velocity at 21°C (m/s)306 ± 4306 ± 4Std.
