“…The propellant manufacturing facility was described previously in detail by Petre et al [15].T he propellants were mixed in as igmab lade mixer using the solvent incorporation method until ad oughj udged to be adequate for extrusion was obtained. The dough was subsequentlye xtruded, cut in cylindrical geometries with no perforations and dried until the weight loss due to solvent evaporationw as negligible.…”

The influence of two selected bistetrazoles, 5,5′‐bis(1H‐tetrazolyl)‐amine (BTA) and 5,5′‐hydrazinebistetrazole (HBT), on the combustion behavior of a typical triple‐base propellant was investigated. Seven propellant formulations, one reference and six others incorporating 5 %, 15 %, and 25 % of either HBT or BTA compounds, respectively, were mixed and extruded into a cylindrical, no perforations, geometry. The resulting propellants showed high burning rates, up to 93 % higher than the reference formulation at 100 MPa. However, the increase in burning rates came at the cost of higher burning rate dependency on pressure, with a pressure exponent as high as 1.4 for certain formulations. HBT‐containing propellants showed notably lower flame temperature when compared to the reference formulation, with a flame temperature reduction of up to 461 K for the propellant containing 25 % HBT. The thermal behavior of the propellants was also investigated through DSC experiments. The addition of bistetrazoles provided lower decomposition temperatures than the pure nitrogen‐rich materials, indicating that the two compounds probably react readily with the −ONO2 groups present in the nitrocellulose and the plasticizers used in the formulation. The onset temperature of all propellants remained within acceptable ranges despite the observed decrease caused by the addition of the bistetrazole compounds.

“…The other two propellants used in this study (LOVA 325 and LOVA 326) were HMX (1,3,5,7tetranitro-1,3,5,7-tetrazocine) based LOVA propellants, which used one HMX crystal size (5 microns) and were developed at Valcartier for a previous study (Petre et al 2011b). Additional information regarding the mechanical and combustion properties of propellants used can be found in the work of Petre et al (2011b). HMX grains manufactured with one particle size are known to be susceptible to cracking during processing (Trumel et al, 2012).…”

“…The processing facility consists of a sigma-blade mixer, an extrusion press and cutting apparatus. A detailed description of the facility was provided by Ramachandran and Drolet (1986) as well as Petre et al (2011b). The LOVA-type formulations produced used a typical solvent-based gun propellant processing, as described in detail by Beaupre and Durand (1990).…”

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.
