High Energy Propellants for Advanced Gun Ammunition Based on RDX, GAP and TAGN Compositions

Abstract

A number of gun propellant compositions based on RDX, GAP, TAGN and combinations thereof were formulated and studied with the aim to select the suitable composition for advanced gun ammunition in respect of processability and ballistic performance. Theoretical thermochemical properties of the compositions were computed using a ‘THERM’ programme and the ballistic performance was evaluated on the basis of closed vessel tests. In addition, sensitivity, thermal characterization, thermal stability and mechanical properties of the compositions were also determined for assessing the suitability for application. A composition containing 28% NC, 45% RDX, 20% TAGN, 6% GAP, 0.7% carbamite and 0.3% resorcinol was found to provide higher level of force constant at relatively lower flame temperature, reasonably good burning rate characteristics and mechanical properties.

Effect of Experiment Environment on Calorimetric Value of Composite Solid Propellants

“…Lalita S. Jawale, Chandrani Dey, Mehilal * , Manoj Gupta, and B. Bhattacharya energy propellants for advanced gun ammunition based on 1,3,5-trinitro-1,3,5-triazacyclohexane (RDX), glycidylazide polymer (GAP) and triaminoguanidinium nitrate (TAGN) has been studied on Julius Peters adiabatic bomb calorimeter 8 . However, this study does not reveal the exact nature of environment applied during the determination of cal-val.…”

RDX Based Enhanced Energy Propellant for Tank Gun Ammunition

“…Superior energy of nitramines is due to positive heat of formation and typical stoichiometry. High Energy Material Research Laboratory (HEMRL), Pune, India had earlier worked on various nitramine based high energy propellants including LOVA (Low vulnerable Ammunition) and high energy LOVA .…”

“…Superior energy of nitramines is due to positive heat of formation and typical stoichiometry. High Energy Material Research Laboratory (HEMRL), Pune, India had earlier worked on various nitramine based high energy propellants including LOVA (Low vulnerable Ammunition) and high energy LOVA [7][8][9][10][11][12]. In addition to the task of defeating more challenging armoured targets, weapon designers are also facing problems of variation of ballistics of gun propellants with temperature.…”

Production and characterization of nanometer explosives

“…The nitramine explosives (RDX, HMX and CL-20) are with high detonation heat, detonation velocity and detonation pressure, and they have been extensively used in plastic bonded explosives(PBX) [1][2][3] and propellants [4][5][6][7][8][9]. The sensitivities of explosives are decreased effectively by reducing the particle sizes, and if the nano particles were obtained, the sensitivities would be greatly decreased [10][11][12].…”
