Abstract

Abstract: A simulation model of the flyer driven by a small size booster explosive is established to optimize the performance of flyer driven by booster explosive in an explosive train. A calculating method of the JWL equation of state (EOS) parameters for booster explosive is proposed. A typical booster explosive JO-9C is chosen to drive metallic flyer in experiment, verifying the accuracy of the proposed simulation model. The velocity and kinetic energy of flyer are chosen as the parameters to evaluate the perfor- mance of flyer. The influences of the charge structure, the diameter of accelerating chamber and the thickness of flyer on the performance of flyer are analyzed. The results show that both the flyer velocity and the charge quantity should be taken into account when the length-to-diameter ratio of charge is 1.5. The diameter of the accelerating chamber should not be greater than that of the charge, so that good flyer morphology and high flying speed would be achieved. If the flyer is too thin, it may easily break. Taking a 5 mm-diameter JO-9C charge as an example, the optimal design is as follows: the length-to-diameter ratio of charge is 1.5, meaning that the charge height is 7.5 mm, the diameter of accelerating chamber is 5 mm, and the thickness of flyer is 0.3 mm. In this case, the velocity and kinetic energy of flyer are 1 663 m/s and 51.79 J, respectively. This work has certain theoretical and practical value for the reliable design of explosive train. Key
