Composition of the condensed detonation products of mixed explosives

It is shown experimentally that in the explosion of mixed explosives that have nitrogen-containing components and a combustible (aluminum, boron, and titanium), conditions under which the condensed explosion products contain mainly nitrides in the form of powders of dispersity 0.1–1.0 μm that are stable when stored in air can occur. The possibility of formation of lower volatile suboxides is shown. Translated fromFizika Goreniya i Vzryva, Vol. 35, No. 4, pp. 92–94, July–August 1999.

Continuous spin detonation of a hydrogen-air mixture with addition of air into the products and the mixing region

Results of an experimental study in a flow-type annular cylindrical combustor with an outer diameter of 30.6 cm are described. The influence of air addition to the products of continuous spin detonation of a hydrogen-air mixture and to the mixing region on parameters of detonation waves, pressure in the combustor, and specific impulse is studied. The range of continuous spin detonation of the hydrogen-air mixture is extended to specific flow rates of the mixture equal to 560 kg/(sec · m²) and fuel-to-air equivalence ratios equal to 0.5–4.4. It is demonstrated that addition of air decreases the detonation velocity, increases the pressure in the combustor and thrust, and decreases the specific flow rate of the fuel. The total pressure loss due to the mixing process and heat transfer to a colder gas increases. The minimum specific flow rate of hydrogen reached in the combustor of the examined geometry is 0.04 kg/(h · N).     

MgH2型复合敏化储氢乳化炸药的制备及其爆轰性能

为了提高乳化炸药的爆炸威力,研制出了一种MgH₂型复合敏化储氢乳化炸药。该乳化炸药采用包覆后的MgH₂与玻璃微球复合敏化,两种材料分别起到含能添加剂和敏化剂的作用。通过研究“热点”数量和包覆材料对炸药爆轰性能的影响,确定了MgH₂型复合敏化储氢乳化炸药的配方。利用水下爆炸实验和猛度实验,研究了MgH₂型复合敏化储氢乳化炸药的爆轰特征参数和水下爆炸特性。实验结果表明,MgH₂型复合敏化储氢乳化炸药的铅柱压缩量为24.3 mm,达到军用炸药的猛度;与传统玻璃微球型乳化炸药相比,其水下爆炸峰值压力虽然下降了4.90%,但比冲击波能、比气泡能和总能量分别提高了7.83%、22.94%和18.32%。MgH₂型复合敏化储氢乳化炸药的猛度和做功能力得到了显著提高。
