The oxidation potential of perchlorates is high, which makes this material suitable for fuels with high specific impulse. Perchlorates are characterized by a ClO4- moiety/anion in their molecular structure and are crystalline materials used in the formation of solid fuels. Ammonium perchlorate (AP) particle size and shape influence the manufacturin...

AbstractThis paper addresses the effect of oxidizer particle orientation on the burning rate of ammonium-perchlorate-based heterogeneous solid propellants. Mesoscale numerical simulations are conducted assuming that oxidizer particles are ellipsoidal and have different orientations with respect to the combustion direction. The particle orientation ...

AbstractThe results of experiments carried out in a laboratory pulsed energy projectile (PEP) device with a high-density charge made by pressing from a fuel mixture and initiated by a low-velocity detonation wave are presented. The muzzle velocity, maximum pressure in the chamber, and the completeness of fuel conversion are determined according to ...

The potential of tetrazole-based ligands for forming energetic complexes applied in pyrotechnics and propellants is demonstrated with the use of 5,5’-(1,3-phenylene)bis(1H-tetrazole) (H2BTB) to generate an energetic complex with high energy. A new energetic complex of PbII-tetrazolate, [Pb2(BTB)2(H2O)8]·5H2O (1), was synthesized and structurally ch...

AbstractThe use of boron-based powder materials in solid propellant compositions is an effective method for increasing the energy characteristics in the combustion chamber due to increasing the released energy through the combustion of boron particles. In this study, powders of amorphous boron and aluminum borides, obtained by the method of self-pr...

AbstractAn experimental study was made of the initiation of detonation of a polymer-bonded energetic condensed system containing glycerol trinitrate, ammonium perchlorate, and aluminum powder by a nanosecond relativistic electron beam with a flux density of 200 J/cm2. It has been found that the velocity of dispersion of gas–plasma formations from t...

V-Cr-Al-O nanospheres were successfully synthesized using V2O5, Al(OH)3, CrO3, and H2C2O42O as the starting materials by a facile one-pot hydrothermal approach. Several techniques containing X-ray powder diffraction, hydrogen temperature programmed reduction, scanning electron microscopy were used to characterize the composition, morphology and red...

AbstractLow-velocity detonation in mixtures of ammonium perchlorate and fuel additives in high relative density charges is an interesting subject for the scientific research, with potential for practical applications in pulse nozzle and projective setups. However, information about the process is scanty and mainly concerns the measurements of the w...

This paper describes the effect of the composition of energy condensed systems, containing glycerol trinitrate, aluminum powder, ammonium perchlorate, and HMX, on their ignition in an electric field with a frequency of 50 Hz. Conditions under which energy condensed systems ignite in an alternating electric field with a frequency of 50 Hz are determ...
