Abstract
In order to understand the influence of the state equation of explosive gas on the calculation results of the explosive volume of high-energy non-ideal explosives,typical aluminized explosive detonation tests were carried out using a 20 L sealed projectile.The temperature distribution of explosive products was tested using an array of platinum resistors.Van der Waals equation and ideal gas state equation were compared and analyzed.The gas pressures inside the projectile under different temperature conditions was accurately measured.Quantitative analysis was conducted on the composition of detonation gas products.The Van der Waals pressure correction coefficient and volume correction coefficient were calcula-ted to be 1.5×10-5 and 2.1×10-4,respectively.The experiment verified the applicability of the ideal gas state equation to describe detonation products.The results indicate that compared to the actual measured pressure and volume,the pres-sure correction term and volume correction term are negligible quantities.The typical explosive gas products of aluminized explosives can be described using a simple linear relationship of p=kT.The state of typical non-ideal explosive products under experimental conditions basically conforms to the assumption of ideal state.关键词
