The separation mechanism is a critical device that transports and releases satellites during launch on-orbit. However, as become smaller more compact, the traditional belt-locking or pyrotechnic release cannot meet micro-nano satellite’s requirements. A novel kinematic system was designed, analyzed, experimentally verified to achieve non-interference non-pyrotechnic of from vehicle while mainta...

From the requirement of continuous matching of bulk metric around the point of brane collision we derive a conservation law for collisions of p-branes in (p+2)-dimensional space-time. This conservation law relates energy densities on the branes before and after the collision. Using this conservation law we are able to calculate the amount of matter produced in the collision of orbifoldfixed bra...

Strontium-based red pyrotechnic colorants have fallen into disrepute due to the harmful influence of this alkaline earth metal on adolescents. In context, energetic character, safety, and combustion benign nitrogen gas nitropyrazoles are used for design corresponding lithiated materials, which investigated as potential replacements in current work. For purpose, lithium salts 3,4-dinitro-1H-pyra...

The use of smoke pyrotechnic compositions bring during use an intoxication risk to the staff located in the immediate proximity. One of the methods for pyrotechnic composition toxicity evaluation consists in the dimensional analysis of the solid particles resulted from the combustion and the determination of the respiratory system intrusion rate. The experimental determinations were performed f...
