Abstract: In order to reduce the thermal decomposition temperature of ammonium perchlorate (AP), an iron-cobalt alginate complex was prepared through the substitution of sodium ions in sodium alginate (SA) with iron and cobalt ions based on the ion exchange principle via spraying, and CoFe2O4@C composite catalyst was obtained by high temperature calcination. The morphology of CoFe2O4@C was characterized by XRD, FT-IR and SEM. The effects of iron-cobalt ion ratio and calcination temperature on the catalytic decomposition of AP were investigated by DSC method when the CoFe2O4@C was added into AP. The results show that SA is converted into iron-cobalt alginate after ion substitute and this composite is amorphous at ambient temperature and pressure. Nano-CoFe2O4 particles are generated in situ after calcination and supported on the carbonized carbon skeleton, which effectively prevents agglomeration of nano-CoFe2O4 particles. When the calcination temperatures are 300, 400 and 600℃, and the mass ratios of iron to cobalt ions are 1:2, 1:1 and 2:1, respectively, all the calcined products are CoFe2O4@C. When the iron-cobalt ion mass ratio of FeCo/SA is 2:1, CoFe2O4@C obtained by calcination at 300℃ reduces the pyrolysis peak of AP by 96.5℃, indicating that the prepared CoFe2O4@C composite catalyst can effectively reduce the thermal decomposition temperature of AP.

Abstract: In order to improve the combustion properties of combustible objects, the microcellular combustible objects were fabricated by the supercritical carbon dioxide (SC-CO2) foaming technology. Scanning electron microscope (SEM) and the closed vessel tests were applied to characterize the cell structure and combustion properties of microcellular combustible objects. The results demonstrated that there were numerous micron-scale cells in the microcellular combustible objects fabricated by the SC-CO2 foaming technology, which enhanced the specific surface area. Both the foaming temperature of 90°C and the foaming time of 15min led to the increase of the cell density and diameter. The closed vessel tests indicated that the microcellular combustible objects performed the shorter burning time (14.66ms) than that of original sample (16.49ms), and the decrement was 11%. The higher foaming temperature, the longer foaming time and the higher RDX mass fraction promoted the spread rate of burning gas of the microcellular combustible objects in burning process because of the higher specific surface area and oxygen balance. Therefore, the microcellular combustible objects foamed by SC-CO2 had a very good application foreground in weapons.

Abstract: In order to solve the problem of emptying explosive, the experimental study and simulation analysis on emptying explosive of condemned ammunition with cavitation water jet are investigated. The mechanism and key technology of cavitation water jet emptying explosive are explained and discussed. The experiments for emptying A-IX-II explosive are carried out on a cavitation water jet device, and the simplified physical model of single-nozzel cavitation water jet emptying explosive is established to numerically simulate the flow distribution of cavitation water jet and the mechanical response of simulation explosive. The results show that both macroscopic high speed water jet and microscopic water jet caused by cavitation contribute to the emptying process of explosive ammunition. Cavitation water jet can empty the A-IX-II explosive of 76-155 caliber cleanly in 15-30minutes with a preferable test stability, and the average diameter of A-IX-II explosive debris is 1-2cm with the maximum size no more than 4cm. The distributions of velocity and pressure of cavitation water jet follow Bernoulli's law, and the maximum velocity can reach to hundreds of meters per second at the contraction section of cavitation nozzle. The cavitation casused by the force unbalance of cavitation bubbles on the surface of explosive ammunition can erode and break explosive effectively. The explosive broken occurs mainly on the contact surfaces of cavitation water jet and explosive. Multi-nozzle will form multiple concentrically annular etch pit zones on the surface of explosive of ammunition.

Abstract: In order to explore the slow cook-off response characteristics of HMX-based aluminized explosive under different constraint conditions, and provide a basis for the design of the slow release structure of the warhead, the characteristics of the ignition process of the typical pressed HMX-based aluminized explosive were analyzed by slow cook-off test, and the response grade of the explosive was compared by adjusting the strength of the cook-off bomb shell and the section area of the pressure relief channel. The results show that the ignition process of the aluminized explosive during slow cook-off contains three stages, namely, a small amount of gas generation in local region, the expansion of the flameless combustion front, and the flaming combustion. For the cook-off bomb without the pressure relief channel, the reaction rate of the explosive charge will increase rapidly when the internal pressure is greater than a certain critical pressure (between 96.5 and 193MPa). For the cook-off bombs with stronger constraint strength and the ratio of the pressure relief channel area to the cross-section area of the charge is greater than 30%, it will present the combustion reaction of the explosive and the structure of the bomb will be intact. Besides, even if the area of the pressure relief channel is larger enough, the shell with low strength can still be damaged during the pressure relief process.

Abstract: In order to investigate the effect of different particle sizes of ammonium perchlorate (AP) on the thermal stability of RDX and the effect of AP on the energy release rule of RDX-based composite explosives, AP/RDX composite explosives with different AP content and particle sizes were designed, and their heat of explosion and detonation velocity were tested. The results show that the AP with particle sizes of 100-150μm, 10-13μm and 2μm all have acceleration on the decompostion of RDX, and the decomposition peak temperature of RDX decreases from 433℃ to 368℃, 417℃ to 365℃ and 375℃ to 321℃, respectively with the decrease of particle size of AP. As the addition of AP particle and its size decreases, the apparent activation energy of RDX in the mixtures decreases from 206 kJ/mol to 188, 170 and 157 kJ/mol, respectively. With the mass fraction of AP increases from 0 to 60%, the detonation velocity and heat of explosion increase from 5390 m/s to 8315 m/s and from 1610 kJ/kg to 5396 kJ/kg, respectively. As the particle size of AP decreases, the detonation velocity increases to 5863, 5902 and 5931 m/s, respectively, while there is no significant impact on the heat of explosion.

Abstract: To understand the slow cook-off phase transition and heat transfer characteristics of DNAN based melt-cast explosives, and provide technology support for their safe use, the cook-off experiment of DNAN-based explosive grain with size of 30mm×60mm was conducted, and the thermal response characteristics was analyzed. The numerical simulation method was used to contrast the phase transition and heat transfer process of Φ30mm×60mm DNAN based melt-cast explosive between the half model and full model. The experimental results showed that the initial temperature of phase transition Ts and the end temperature of phase transition Te of DNAN based melt-cast explosive were about 81.8℃ and 95.3℃, respectively. Response level was combustion reaction. Through numerical simulation, it was found that the ignition position of DNAN based melt-cast explosive was near the edge of the top of the explosive grain and the response temperature Tr was about 203.8℃ when the explosive grain was placed vertically. The main heat transfer mode in phase change process changed from heat conduction to asymmetric distribution in phase-change region resulted from thermal convection. So the full model should be employed in slow cook-off numerical simulation of DNAN based melt-cast explosive. The density and thermal conductivity of DNAN based melt-cast explosive decreased during phase transition. So the phase transition rate of DNAN based melt-cast explosive experienced four stages: fast velocity, zero velocity, medium velocity and low velocity.

Abstract: In order to improve the dispersion stability of nano-aluminum in high-density hydrocarbon fuels(HF-X) suspension, the effect of the dispersant mass fraction, dispersion temperature, mass fraction and granularity of nano-Al, ultrasonic dispersion power and time of nano-Al in HF-X suspension on the dispersibility of nano-Al were investigated by sedimentation rate test. The morphology of nano-aluminum powder before and after dispersion was compared by SEM, the contact angle of nano-Al in the dispersant/HF-X solution was tested and the influence mechanism of dispersant was analyzed. The results show that the dispersion time of suspension of polymer dispersant containing amine anchoring group (HS) is longer than that of dispersant containing block copolymer (HT). The sedimentation rate of nano-aluminum in the HF-X suspension increases with the increase in the mass fraction and particle size of nano-aluminum powder, among them, the maximum mass fraction of nano-aluminum powder in HF-X suspension is up to 7.5%, and the mixture becomes paste when it is 10%. With increasing the dispersant HS50 mass concentration, the sedimentation rate of nano-aluminum powder decreases. When mass concentration of HS50 is 0.02g/mL, the sedimentation rate is 9.85×10-6g/(cm2?s), which tends to be constant. With increasing the ultrasonic dispersion power and time, the sedimentation rate of nano-aluminum powder decreases, which has a significant effect on the dispersion stability, while the dispersion temperature has little influence. The contact angle of nano-Al in HS/HF-X solution is much larger than that in HT/HF-X solution. The HS-series dispersants have better dispersion stability, which is related to the spatial retardation of polymer chain to nano-aluminum powder.

Abstract: To study the aging properties under loading action of induced pressure on nitrate ester plasticized polyether (NEPE) propellant, double stress accelerated life tests were performed at 75℃ and 1MPa. The effects of temperature and pressure on the combustion, energy, mechanical properties, safety characteristics of NEPE propellant were studied. The change mechanism of mechanical properties of NEPE propellant was analyzed by cross-linking density, dynamic mechanical properties and scanning electron microscopy. The results show that during accelerated aging at 75℃ and 1MPa for 30 days under the combined action of temperature and pressure, the heat of detonation of NEPE propellant is 6007-6192kJ/kg, the burning rates is 10.36-10.64mm/s, the mass fraction of stabilizer is 0.43%-0.48%, which do not change with aging time. The tensile strength decreases with the increase of aging time, and its value decreases from 0.612MPa to 0.433MPa with a change rate of 29.2% after 30 days of aging, indicating that the change of mechanical properties is the main failure model of propellant. The failure mechanism under the temperature-pressure double stress loading action is that temperature degrades the binder, destroys the nodes in cross-linking network and decomposes the solid particles to cause dehumidification, and the compressive stress strengthens the dehumidification phenomenon, which leads to the rapid decrease of mechanical strength.

Abstract: In order to apply the click chemical curing system of polybutadiene into the practical process, the non-isothermal differential scanning calorimetry (DSC) method was used to investigate curing reaction kinetics of terminal alkynyl polybutadiene (PTPB)-triazide acetate propane (TAP)-terminal azido polyethylene glycol (APEG) system. The curing temperature and kinetic parameters of this curing system were calculated by the heating rate-temperature extrapolation method, the Kissinger model, the Ozawa model and the Crane model, respectively.The isothermal curing behavior of the curing system was predicted by nth order kinetics model and model free kinetics (MFK). The results indicate that this system has a low curing activity at 60℃ and the curing rate constant is only 3.13×10-5 min-1. When the mass fraction of the catalyst (CuCl) is 0.1%, the rate constant is 5.6×10-3 min-1, which is two orders of magnitude higher than that of the hydroxyl terminated polybutadiene-toluene diisocyanate (HTPB-TDI) curing system. The MFK prediction result is closer to the measured result.In addition, when the mass fraction of CuCl is 0.1%, the curing system requires only 10.4h to complete curing at 30℃.

Abstract: In order to evaluate the relationship between the ligand structure and catalytic performance of metal aromatic complexes used as combustion catalysts, the influence of ligand number and position on the catalytic performance were reviewed. The catalytic effects of complexes containing hydroxyl, amino and nitro groups were analyzed and the influences of their number and positions on the catalytic performances were also discussed. It is found that, the more the hydroxyl groups on the benzene ring of aromatic complex, the better the catalytic effects would be. For the complexes containing amino groups, their catalytic activities for propellant combustion are closely related to the positions of amino groups and the activities are in the order of ortho>parallel>meta. As for the complexes containing nitro groups, however, the location of substituted group has a greater influence on the catalytic activity than the number of groups. How to choose metal monocyclic aromatic complexes as highly efficient combustion catalysts was also proposed. 57 References are attached.

Abstract: In order to study the effects of N-doped graphene oxide (N-GO) on the thermal decomposition of cyclic tetramethylene tetranitramine (HMX), it was obtained by hydrothermal reduction using graphene oxide (GO), which was prepared by the Hummer method, and urea as the nitrogen source. The as-prepared N-GO was characterized by X-ray diffraction apparatus (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FT-IR). Then the N-GO/HMX composite was achieved by combining HMX and N-GO. The catalytic effects of N-GO on the thermal decomposition of HMX were evaluated by differential scanning calorimetry (DSC). The results show that N-GO is more effective in promoting the thermal decomposition of HMX than rGO. In the existence of N-GO, the exothermic decomposition temperature of HMX is decreased from 283.16℃ to 281.96℃. Moreover, the corresponding apparent activation energy and pre-exponential factor are decreased from 514.61kJ/mol and 1046.86s-1 to 484.36kJ/mol and 1044.05s-1, respectively. The promoted decomposition of HMX is attributed to the increased charge densities and catalytic active sites on the surface of GO, which is due to the lone electron pairs introduced to GO after N-atom doping.

Abstract: To improve the penetration performance of shaped jet, an advanced M-shaped truncated-cone liner was proposed on the basis of hyper-velocity jet theory, and numerical simulation were performed by ANSYS/LS-DYNA software to study jet formation and penetration against steel target. The jet performances of the M-shaped liner and cone-shaped liner were compared and vertified by static armor experiment. The results show that upon hyper-pressure detonation front of explosive charge, the M-shaped section of M-shaped truncated-cone liner collapses into inner-and-outer annular jets, and inner-and-outer circular jets converge into secondary annular jets, finally a higher-velocity jet tip is obtained with 4.2% increase on the basis of conventional cone-shaped liner, at the meantime a more robust penetration capability is also achieved with 36.06% increase on the basis of conventional cone-shaped liner, which exhibit excellent agreement between numerical simulation and field test with a desirable deviation of less than 5%.

Abstract: The -NF2 substitution derivatives of RDX and HMX were studied at the B3LYP/6-31G** level of density functional theory. The condensed-phase heats of formation(HOF) were predicted with isodesmic reactions and Hess law. The density (ρ) was calculated by the Politzer method. The heat of explosion(Q), detonation velocity (D), and detonation pressure (p) were estimated by the K-J equation. The effects of -NF2 on HOF, ρ, Q, D, and p were discussed. The stability of compounds was evaluated using bond dissociation energies (BDE) and impact sensitivities (H50). The possible initiation mechanism of thermal decomposition was discussed. The results show that -NF2 substitution can reduce the heats of formation. The ρ of the compounds ranges from 1.96 to 2.34g/cm3, which is higher than that of RDX and HMX. The D of all derivatives is 8.85-9.98km/s, and the p is in the range of 35.07-50.99GPa. Most compounds have better D and p than RDX and HMX, and -NF2 contributes a lot to D and p. The BDE of all compounds is in the range of 90-160kJ/mol, which meets the requirements of high-energy material stability. The sequence of the predicted H50 values is basically consistent with the BDE results. The introduction of more -NF2 groups in the compounds usually reduces the stability. Therefore, most of the -NF2 derivatives of RDX and HMX have good detonation performance and stability and can be promising candidates of high energy density compounds.

Abstract: To study the effect of aluminum powder content on the metal acceleration ability of alumized explosives and obtain the reaction law of aluminum, a series of 25 mm cylinder tests contained 5 different explosives (RDX, RDX/Al, RDX/LiF)were performed. The expanding velocities of cylinders were measured using Photonic Doppler Velocimetry(PDV). Based on JWL equation of state, a new fitting method was proposed to obtain the state equation containing the secondary reaction of aluminum in detonation products. The results show that for 2μm aluminum particles, 25mm cylinder tests combining PDV could characterize the secondary reaction of aluminum.The reaction delay time of aluminum in detonation products was less than 3μs, and the reaction lasting time was between 10 to 15μs. The numerical simulation results of cylinder expanding using state equation in aluminized explosives by new method were in good agreement with the experimental results, and the state equation could be used to calculate the reaction progress of aluminium semi-quanlitatively. Among 3 kinds of RDX/Al formulations, the formulation containing 15% aluminum presented the best metal acceleration ability. Thus, both detonation heat and volume of gas products should be synthetically considered to obtain the best performance when a new explosive formulation was designed.

Abstract: In order to understand the viscoelasticity and impact damage characteristics of azido polyether propellant in the ignition process under low temperature and high loading frequency,dynamic mechanical analysis, impact loading test and X-ray micro-tomography (X-μCT) were employed to investigate the dynamic mechanical properties, impact fracture and damage behavior. The results revealed that the critical transition temperature (Tc) shifted to high temperatures with the increase of loading frequency, thus leading to the obvious deterioration of viscoelasticity. Under the conditions of-40℃ and 103Hz,the corresponding Tc of the samples with glass transition temperature of -42.4, -46.7 and -50.8℃ were determined to -29.1, -34.9 and -38.2℃, respectively. It was also observed by X-μCT that the ammonium perchlorate (AP) particles in glassy azide polyether propellants were seriously damaged under an impact energy of 2 J, and the cracks between AP particles and the glassy matrix coalesced to generate macroscopic fractures of propellant samples. On the other side, under the condition of -20℃ and 103Hz, at which the samples were in high elastic state, the impact only caused microcracks of the AP particles.

Abstract: In order to study the explosion properties of 2,6-diamino-3,5-dinitropyridine-1-oxide (ANPyO) based polymer binder explosive (PBX), and expand its application in the military and civil fields such as petroleum perforation and low vulnerability explosives, three kinds of ANPyO-based PBX explosives were prepared by solution-suspension-distillation method using ANPyO as the main explosive, fluororubber F2311, F2603 and nitrile rubber NBR-26 as binders and the detonation velocity and mechanical sensitivity were tested. The explosion power and perforation depth of steel target were determined by means of shaped charge. The results show that the detonation velocities of the three ANPyO-based PBXs are about 7300m/s, the mechanical sensitivity are low,and the perforation depth are all higher than 120mm, which are higher than that of the typical insensitive explosive and can meet the requirements of low-vulnerable explosives with insensitivity and high energy. The perforation depth and hand-hole diameter of NBR-26 sample are better than those of the fluororubber samples. The penetrating volume of NBR-26 sample is 76.4% of 8701 explosive in explosive power test, and the shaped charge jet is more concentrated than that of 8701 explosive. The mechanical sensitivity of ANPyO-based PBX is close to that of the typical insensitive explosive, and its explosion properties is close to that of the high-energy mixed explosive, indicating that ANPyO can be use as a new type of high-energy insensitive energetic material.

Abstract: For the defects of high sensitivity and unstable stability of a certain organic peroxide,a modification processing of blending and coating was adopted, and the modification mechanism was also investigated. The safety properties including mechanical sensitivity, flame sensitivity, thermal sensitivity as well as the energy properties including shock wave overpressure, explosion temperature were evaluated. The results show that the mechanical sensitivity of the modified organic peroxide is decreased sharply.The impact sensitivity increases from 9.9cm to 13.8cm, and the explosion probability by friction sensitivity decreases from 76% to 4%. The flame sensitivity and thermal sensitivity have no significant changes, revealing that the integral safety degree has been significantly improved. The shock wave overpressure and impulse at 1m on the ground from the explosion center are increased by about 50% and 20%, respectively. The fireball temperature increases nearly 1200℃, the overall performance of explosion has been significantly improved.The results indicate that the method of blending and coating can reduce the sensitivity and increase the energy of the organic peroxide.
