“…The JA2 gun propellant consisting of 58.21 % NC (13.2 % N), 15.79 % NG, 25.18 % DEGDN, 0.74 % Akardite II, 0.05 % MgO and 0.03 % graphite [9,10] was selected as a reference formulation. Three series of NB gun propellant samples were prepared using cyclic nitramine (RDX, HMX or CL-20) and TEGDN to replace NG and DEGDN in the JA2 gun propellant composition in order to reduce sensitivity, the formulations are given in Table 1.…”

“…Therefore, the possible materials to replace or partially replace NG as the main plasticizer in DB gun propellant compositions are continuously explored [3][4]. The JA2 gun propellant is a modified DB gun propellant consisting of NC, NG and diethylene glycol dinitrite (DEGDN), which has been used in 120 mm tank ammunition marked by M829 A1/A2 with APFSDSÀ T (Armor Piercing, Fin Stabilized, Discarding Sabot-Tracer) projectile [5][6][7][8][9][10]. DEGDN is used as an energetic plasticizer in JA2 gun propellant to partially replace NG due to its superior properties from a ballistic standpoint and lower handling hazards [11][12].…”

This study mainly explored the performance characteristics of nitramine‐based (NB) gun propellants using TEGDN as an energetic plasticizer by experimental method. Three series of NB gun propellant samples with RDX, HMX or CL‐20 were prepared referring to the formulation of JA2 gun propellant. Their thermochemical characteristics, explosion heat, chemical stability and compatibility, impact, friction and electrostatic spark sensitivities, and compressive strength were determined by various instruments. The experimental results indicated that the NB gun propellant samples with RDX have lower decomposition temperature, and those with CL‐20 have higher thermogravimetric loss. Three series of NB gun propellant samples have good chemical stability and compatibility, and their explosion heat is close to that of JA2 gun propellant, but their sensitivity is lower than that of JA2 gun propellant. The maximum stress of three series of NB gun propellant samples decreases with increasing cyclic nitramine (RDX, HMX or CL‐20) content, and their compressive strength is better than that of JA2 gun propellant.

A short history of nitrocellulose (NC) use in propellants is discussed. The advantages and disadvantages of NC as a semi-synthetic component of powders and rocket propellants are presented. Based on the conventional classification of propellants, the options of eliminating nitrocellulose in different types of powders and rocket propellants are discussed in detail. The analysis shows that in the foreseeable future, the elimination of NC in single-base and double-base propellants is highly unlikely. The observed trends in triple-base propellant development also does not show any tendencies in the elimination of NC, only the replacement of nitroguanidine with cyclic nitroamines. However, the elimination of NC in LOVA composite propellants is probable. Synthetic, rubber-based solid composite rocket propellants, with ammonium perchlorate as the oxidizer, are the only ones not dependent on NC.
