Studies of Free Field and Confined Explosions of Aluminium Enriched RDX Compositions

Abstract

Research on the effect of aluminium contents and its particle size on free field and confined explosions characteristics of RDX‐based compositions containing 15–60% aluminium was carried out. Parameters of blast waves produced by charges of the investigated explosives detonating in an open space were measured by the use of piezoelectric gauges. Simultaneously, photodiode set‐ups were used to measure light output of the detonating charges. Quasi‐static pressure measurements were conducted in steel chambers of 0.15 and 7 m3 volume filled with air. Moreover, the heat of detonation was measured with a calorimetric set in a 5.6 dm3 bomb filled with argon. The results of QSP and detonation heat measurements were compared with those obtained from thermochemical calculations.

Experimental Study of the Explosion of Aluminized Explosives in Air

“…Sequential reaction zones may depend on particle size and other factors [7]. There are many practical applications and a large number of studies devoted to the effect of particle size, aluminum content and other factors on aluminized explosive [8][9][10][11][12]. With decreasing particle size of the aluminum powder, the detonation velocity is decreased and the heat of explosion is increased.…”

“…The blast effect from military high explosives such as TNT has been widely reported [20][21][22], and the detonation properties of aluminized explosives have been studied in recent years [10][11][12]23]. The chemical processes and the multiphase fluid dynamics that occur within a fireball from of an aluminized explosive are complex.…”

Combustion heat of the Al/B powder and its application in metallized explosives in underwater explosions

“…More recently, many papers [4][5][6][7][8][9] have been aimed at investigating the effects of the particle size and aluminum content on the performance and sensitivity of various explosives. It has been found that the detonation velocity decreases and the explosion heat increases with decreasing particle size of the aluminum powder.…”

Materiały wysokoenergetyczne (MW) – Innowacje w aspektach środowiska przyrodniczego

“…mechanicznego, termicznego, elektrycznego lub chemicznego -np. rozkładu autokatalitycznego) [2,3,5,[10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Składniki MW stosowanych w górnictwie (MWG) to nie tylko substancje stwarzające zagrożenie występowania wysokoenergetycznych procesów, ale również i zagrożenie dla zdrowia powodowane oddziaływaniem produktów skutkującym alergizująco, kancerogennie i/lub toksycznie nawet ze skutkiem śmiertelnym [28][29][30].…”
