125 mm HE, HEAT &APFSDS

Description

Single base seven perforated propellant cylindrical grain, 12/7 VA containing Nitrocellulose (NC) and Diphenylamine (DPA) and tubular propellants: 15/1-240 and 15/1-352 is a kind of single base propellant containing Nitrocellulose (NC) and Diphenylamine (DPA). 12/7 VA propellant is used for 125mm Heat and HE ammunition. This ammunition is used for 125mm gun fitted on T-72 8T-80 tank. 12/7 VA, 15/1-240 and 15/1-352 propellants are used in propelling charge in APFSDS ammunition for 125mm tank gun type T72 BALLISTIC SPECIFICATIONSType of propellantSeven perforated (12/7 VA)Tubular 15/1 – 240Tubular 15/1 – 352Length (mm)13.5 -15.6235 – 240344 -352Hole diameter (mm)0.50 – 0.701.50 – 1.61.85 -2.0Web thickness(mm)1.1 -1.251.45 -1.551.45 -1.55Total volatiles (%)≤ 3.7≤ 3.5≤ 3.8External moisture (%)1.0 -1.81.0 -1.61.0 -1.8Residual solvent (%)≥ 1≥ 1.3≥ 1.3Stability at 134.5 °C≥ 40≥ 40≥ 40 TECHNICAL SPECIFICATIONSType of propellantHEHEATAPFSDS (BM42)Total charge (gr)~ 5200~ 5200~ 8200Average Velocity (m/s)850 ± 7905 ± 71700Std. dev. of Velocity (m/s)33≤ 6.5Average pressure at 15° (kg /cm2)≤ 3500≤ 3000≤ 4350Average pressure at +63°C≤ 405035005200
