Using the pressure comparing method to measure the pressure p_exp and p_Alwith manganin stress gauges on the surface of JB-9001 and LY12 aluminum samples impacted simultaneously by a LY12 aluminum flyer,we obtained the shock Hugoniot of insensitive high explosive JB-9001.
The present situation of theoretical study and the main influence factors of the hot spot ignition period about the performance of the shock wave initiation of heterogeneous high explosives are discussed. The two phase viscidity elasticity initiation model for the shock wave initiation of high explosive have been used to simulate influence factors to the hot spot ignition period.
The energetic leadless compound Ba(NTO)·3H 2O is a low sensitivity and high energy explosive. It is proved to be a good combustion catalyst by TGA and DSC analysis and formula experiment. The Ba compound can lower the characteristic signal of the propellant and decrease environment pollution .
Based on the thermal reaction-diffusion equations of the thermal explosion theory, by the way of theoretical analysis and numerical simulation, the problem of high energy explosive's friction sensitivity is studied.
Hexanitrohexaazaisowurtzitane(HNIW),the most powerful high energy density compound ever tested,was first synthesized by A. T. Nielsen in 1987.Considered as a tomorrow's high energy explosive,it has drawn much attention of many countries.
In order to explore the possibility of utilizing polynitrosulfamides and polynitrothione as high explosives, three new sulfo-eompounds: 2, 5-Dinitro-2, 5-diazacyclopentanesulfone(Ⅰ), 2, 4, 4, 6-Tetranitro-2, 6-diazacyclohexanesulfone(Ⅱ) and 2, 4, 6-Trinitro-2, 4, 6-triazaeyelohexanethione(Ⅲ), were synthesized and some of their properties and detonation parameters were determined.
A high energetic explosive compound, 4,10-dinitro-2,6,8,12-tetraoxa-4,10-diazaisowurtzitane(TEX) synthesized by different routes is reviewed. The properties of TEX, such as explosive performance, thermal decomposition, friction sensitivity and impact sensitivity are summarized. It can be concluded that energy lever of TEX is higher than RDX, even exceeds TATB. Moreover, TEX is high solids pressable, extrudable explosive or simple castale explosive.
In , the detonation of a solid high explosive was used to produce population inversion in the gas mixture CO2-N2-He(H2O).
The NEZND theory identified the nonequilibrium excitation processes that precede and follow the exothermic decomposition of a large high explosive molecule into several small reaction product molecules.
Thus an analytic formula with two parameters of high explosive (i.e.
Shock response of the commercial high explosive Detasheet
The mechanical and chemical response of the flexible commercial high explosive DetasheetR is studied under controlled impact and plane-wave, high explosive loading.
The convective combustion of porous gunpowder and high explosives is an intermediate stage in the transition from layered combustion to detonation [1, 2].
A study is made of one-dimensional nonstationary problems of the combustion and detonation of aerosuspensions of unitary fuels or propellants, which contain the oxidant as well as the combustible material (gunpowder, high explosives).
The structure of detonation waves in air suspensions of unitary fuels (fuels containing an oxidant such as gunpowder and high explosives) is investigated.
An improved method for measuring the electric conductivity profile behind the detonation front in dense high explosives has been developed, which provides for a spatial resolution better than 0.1 mm.
A mechanism of the initiation of hotspots in heterogeneous solid high explosives was considered.
