GAP对高能硝胺发射药力学性能及燃烧性能的影响
Effect of GAP on the Mechanical and Combustion Performance of High Energy Nitramine Gun Propellant
摘要
Abstract
To improve the mechanical performance of high energy nitramine gun propellant,the single perforation cylinder propellant containing GAP was prepared.The impact and compression performance of the gun propellant were studied by a material testing machine.The internal morphology of the gun propellant was observed by SEM and the combustion performance was analyzed by a closed bomb test.The results show that the mechanical perform-ance of the high energy nitramine gun propellant can be improved by adding GAP.When the mass fraction of GAP is 1 .5%,the impact strength of high energy nitramine gun propellant at low temperature can be increased from 4 .5 1 kJ/m2 of basic formula to 5.58 kJ/m2 .Adding GAP makes the bonding strength between the interfaces of solid filling and binder system enhance and the dehumidifying phenomenon reduce.With increasing the mass fraction of GAP,in comparison with the basic formula,the burning rate pressure exponent (n)of the perforation cylinder propellant increases,and the explosion temperature (Tv )and impetus (f)of gun propellant decrease gradually.When the mass fraction of GAP is 3.5%,thef,Tv decrease by 1.41%,3.69%,andnincreases by 0.51%,respectively.关键词
