Abstract Reactive multilayer systems consisting of alternating nanoscale Al and Ni layers are applicable in joining, various pyrotechnic applications thermal batteries. Since diffusion based high-temperature synthesis occurs without the presence air, efforts have focused on investigating understanding fundamental reaction processes characteristics. The aim this study is to expose reactive multi...

This paper has been utilizing the simultaneous ThermoGravimetric analysis and Differential Scanning Calorimetry (TG–DSC) to investigate the thermal decomposition of magnesium-sodium nitrate pyrotechnic composition based HTPB resin. The thermal behaviors of different samples with various fuel-oxidizer ratio contents were determined. Decomposition kinetic was investigated by evaluating the in...

This article is of a scientific and research nature. Its subject the humane protection animals, expressly declared by Polish legislator in provisions Animal Protection Act, as regarded context wide access to individual use fireworks private persons. The author seeks an answer question whether legislator’s high-sounding declarations expressed providing for animals Poland, are reflected respectiv...

Abstract. Shock loads are very high amplitude and short duration transient loads. They produced in space structures by pyrotechnic devices placed the launchers initiating stage or fairing separations. While spacecraft structure is not susceptible to this range of frequencies, electrical units could be seriously damaged during launch phase. tests performed on verify if they withstand loads, thus...

This paper presents an algorithm for automatic detection of erroneous amplitude and phase components a sample’s optical field, acquired by holographic tomograph with limited angle projection. By applying image processing methods statistical analysis to find remove unfit projections, the quality tomographic reconstruction 3D refractive index distribution object is greatly improved. The proposed ...

Abstract The emergency transformation of various aspects life and business these days requires prompt evaluation autonomous vehicles. One the primary reassessments deals with applicability vehicle passive safety system to protection arbitrarily positioned passengers. To mitigate possible risks caused by simultaneous deployment several big airbags, a new principle their operation is required. He...

Using pyrolants instead of warhead charges can release red light and thick smoke for target practice to highlight the safety impact point dud disposal. In order find ideal material, combustion kinetic properties two Zn–Mg alloys at critical proportions were investigated. Thermogravimetry/differential scanning calorimetry (TG/DSC) experiments in pure oxygen conducted with atomized alloy powder r...
