Projectile Impact Ignition and Reaction Violent Mechanism for HMX‐based Polymer Bonded Explosives at High Temperature

16-Mar-2017 | Dai Xiaogan, Wen Yushi, Wen Miaoping, Huang Fenglei, Li Ming, Deng Chuan, Propellants, Explosives, Pyrotechnics, 2017

Abstract Determining the mechanism of transition from projectile‐impact ignition to detonation is a complex and difficult task with strong practical applications. Ignition due to low‐velocity projectile impact cannot be properly explained by the available theories. We attempted to determine ...

Direct Determination of Effective Spectral Emissivity of Hot Burnt Gas using Absolutely Calibrated Radiometric Spectrometer

16-Mar-2017 | Wondong Lee, Kiwook Han, Jae Won Hahn, Propellants, Explosives, Pyrotechnics, 2017

Abstract Measurement of the radiative characteristics of a flame is important in the field of combustion diagnostics to better understand combustion processes, fuel performance, and combustion engine efficiency. Flame emissivity is one of the most important parameters for investigating such ...

Statistics of Density, Temperature and Air Gaps on the TATB Cylinder Test

02-Mar-2017 | P. Clark Souers, Lisa Lauderbach, Franco Gagliardi, Clif Mortensen, Propellants, Explosives, Pyrotechnics, 2017

Abstract Duplicate cylinder tests (CYLEX) have been run on PBX 9502 and LX‐17. The 95 % error in the absolute value of the derived detonation energy density is about ±1 % whereas the 95 % error of the difference error is ±0.5 % or better. The analytic model has been upgraded with a better ...

Conditions of Millisecond Laser Ignition and Thermostability for Ammonium Perchlorate/Aluminum Mixtures

02-Mar-2017 | Valerii Medvedev, Vladimir Tsipilev, Aleksander Reshetov, Aleksander Ilyin, Propellants, Explosives, Pyrotechnics, 2017

Abstract The experimental investigations of laser‐induced ignition and heat action of ammonium perchlorate and aluminum powder mixtures are presented in this paper. A laser pulse with wavelength of 1.06 μm and duration of 3.5 ms was used. Powder mixtures of different dispersion were tested, ...

Comparison of Performance of Fast–reacting Nanothermites and Primary Explosives

28-Feb-2017 | Boris Khasainov, Marc Comet, Bernard Veyssiere, Denis Spitzer, Propellants, Explosives, Pyrotechnics, 2017

Abstract The main features of nano‐sized thermites are reviewed with the purpose to compare the performance of most reactive nanothermites showing high combustion front velocities of up to 2500 m s−1 with that of primary explosives. Because these regimes do propagate only at very low relative ...

Research on Feasibility of Several High Density Materials for EFP Liner and Material Selection Criteria

27-Feb-2017 | Li Ding, Jianwei Jiang, Jianbing Men, Shuyou Wang, Mei Li, Propellants, Explosives, Pyrotechnics, 2017

Abstract In order to find new kinds of EFP liner materials with high density, W alloys, Ni, Mo, U, and U alloy were selected to be tested. Both liner test and flyer plate test were carried out in experiment, with existing EFP liner materials being testified as reference. It turned out that ...

Experimental Study on Impact–induced Initiation Thresholds of Polytetrafluoroethylene/Aluminum Composite

27-Feb-2017 | Chao Ge, Yongxiang Dong, Wubuliaisan Maimaitituersun, Yuming Ren, Shunshan Feng, Propellants, Explosives, Pyrotechnics, 2017

Abstract Impact experiments were conducted with a gas gun to investigate the impact‐induced initiation thresholds of a polytetrafluoroethylene/aluminum (73.5 wt % and 26.5 wt %) composite. Targets of steel, aluminum, and low‐density polyethylene materials and sample rods of four different ...

Effect of Bonding Agent on the Mechanical Properties of GAP High‐Energy Propellant

23-Feb-2017 | Jingke Deng, Xiaoqing Wang, Guoping Li, Yunjun Luo, Propellants, Explosives, Pyrotechnics, 2017

Abstract Three kinds of bonding agent were chosen to improve the mechanical properties of GAP high‐energy composite propellant based on GAP, BuNENA, HMX, AP, and Al. These bonding agents are N,N′‐bis(2‐hydroxyethyl) dimethylhydantoin and 1,3,5‐trisubstituted isocyanurates (BA1), ...

The Correlation between Chemical Stability and Binder Network Structure in NEPE Propellant

22-Feb-2017 | Wan'e Wu, Chen Chen, Xiao Fu, Chao Ding, Guang Wang, Propellants, Explosives, Pyrotechnics, 2017

Abstract The correlation between chemical stability and binder network structure is investigated to explore the aging mechanism of NEPE propellant. Through 70 °C aging storage experiments, propellant samples of different aging time periods are obtained every 7 days. The relative contents of ...

Thermal Decomposition Behaviors and Burning Characteristics of Ammonium Nitrate/Polytetrahydrofuran/Glycerin‐based Composite Propellants Supplemented with MnO2 and Fe2O3

22-Feb-2017 | Makoto Kohga, Propellants, Explosives, Pyrotechnics, 2017

Abstract Although a polytetrahydrofuran (PTHF) blend with added glycerin as a crosslinking modifier is an effective binder for improving the performance of a propellant, a burning catalyst is required for the combustion of the ammonium nitrate (AN)/PTHF/glycerin propellant. MnO2 and Fe2O3 are ...
