“…The deterred propellant was subjected to CV evaluation at 0.2 g/cm 3 loading density in a 700 cm 3 CV after conditioning at -20, 21, or 55 °C for 24 h to determine ballistic parameters such as P max , (dP/dt) max , force constant, α, β, rise time (in ms), relative force (RF) and relative vivacity (RV) [16,17,[19][20][21][23][24][25]. In a CV firing, a tourmaline piezo-electric gauge was used for pressure measurement.…”

In this work, the energetic plasticizer N-n-butyl-N-(2-nitroxyethyl) nitramine (Bu-NENA) was used as a deterrent coating for a triple base propellant (TBP) that finds application in large caliber guns. Closed vessel (CV) evaluation was performed to study the ballistic performance of the deterred propellant. A TBP containing nitrocellulose (NC), nitroglycerine (NG) and nitroguanidine (NQ) was coated with an energetic plasticizer using a solution of Bu-NENA. The Bu-NENA coated propellant exhibited inhibition to burning resulting in a reduction in the values of the ballistic parameters viz. (dP/dt)max, burning rate coefficient (β) and relative vivacity (RV), while the pressure index (α) and rise time were increased. The trends obtained during this work display the potential of Bu-NENA as deterrent.[27] Jeunieau, L.; Lefebvre, M.H.; Fonder, N.; Guilaume, P.

“…The introduction of bu-NENA based gun propellant formulations would allow a better and mechanically improved, energetically enhanced, and less sensitive gun propellant [10][11][12][13][14]. There are some studies concerning their synthesis [15][16][17] and their explosive properties as insensitive energetic explosives [18][19][20].…”

“…Higher energy density has been always the theme of solid propellant development. 1,2 As a key component of solid propellant, it is meaningful to develop energetic binders to enhance the overall energy level of propellant. Among numerous energetic binders, glycidyl azide polymer (GAP), [3][4][5][6][7] which enjoys the predominant advantages of high energy level, moderate mechanical sensitivity, low gas characteristic signal, and environmental friendliness 8 , has attracted wide attention and achieved practical application in the field of solid rocket propellants.…”

A kind of glycidyl azide polymer (GAP)‐based composite has been fabricated using propargyl‐terminated ethylene oxide‐tetrahydrofuran copolymer (PPET) with two (p‐) and three (t‐) alkyne functionalities via Huisgen reaction. Independent upon the PPET functionality, both crosslink densities and mechanical properties for two GAP/PPET systems showed a positive‐interrelation changes of initial increase and subsequent decrease with an increase of azide/alkyne molar ratios. At equivalent of azide/alkyne molar ratios, the composites containing t‐PPET with higher alkyne functionality exhibited better mechanical properties, while those with two alkyne functionality presented lower glass transition. Under the regulation of alkyne functionality as 3 and azide/alkyne molar ratio as 3:1, the tensile strength, Young's modulus and breaking elongation could simultaneously reach the maximum values of 1.38 MPa, 4.07 MPa, and 122.5%, which was ascribed to optimal participation of azide/alkyne reaction into network construction. Overall, this study provides an additional optimization route for network‐structured binders in solid propellant system. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 48016.
