Autor: V. A. Sudovtsov, A. I. Tolshmyakov, M. D. Tarasov, I. I. Karpenko

Publikováno v: Combustion, Explosion, and Shock Waves. 43:465-467

The detonation temperature of pressed PETN grains with a relative volumetric concentration of air pores of 0.0047–0.147 was measured using an optical fiber pyrometer at wavelengths of 678 and 487 nm. The nonequilibrium nature of the radiation of th

Publikováno v: Journal of Applied Mechanics and Technical Physics. 36:341-346

It is known that the interface between two media of unequal densities is unstable if a constant acceleration is directed from the ligh medium toward the heavier one. In that case small initial perturbations grow exponentially. Conversely, if the acce

Cumulation jets in microchannels inside explosive materials

Autor: V. A. Sudovtsov, M. Yu. Tarakanov, A. I. Tolshmyakov, M. D. Tarasov, V. S. Petushkov

Publikováno v: Combustion, Explosion, and Shock Waves. 35:345-347

Fiber optic light guides with diameters of 0.125 mm are used to measure the velocity of jets formed in microchannels inside plastic explosives. The velocity of the head of a jet can exceed the normal detonation velocity by a factor of two in air-fill

Publikováno v: SPIE Proceedings.

In this work we employed two-wave optical pyrometer to record characteristics of light emission and brightness temperature in shock and detonation waves. Light is transmitted to photoelectronic multiplier over a fiber light conductor with its end loc
