In order to increase the utilization efficiency of laser slapper detonator,it's necessary to improve and optimize the flyer structure.On the basis structure of flyer,the C/Al/Al_2O_3 /Al multi-flyers were prepared by the magnetron sputtering,and the performances of flyers were studied by scanning electron microscope.Taking advantage of photonic dopper velocimetry(PDV),it is found that the accelerating processes of flyers with different parameters are not same,and multi-flyer with the 0.05/0.7/0.7/20.0 μm thickness 1.0 mm diameter reaches a maximum velocity of 2301 m · s~(-1).C ombined with the analysis of physical properties,the influence of each material used in multi-flyers were discussed.Results show that the velocity of multi-flyer is influenced by reflectivity,vaporization enthalpy and thermal diffusivity of graphite layer,as well as the compactness,ionization energy and thermal conductivity of alumina layer.The accelerating time of multi-flyer is determined by the physical properties of thermal conductivity of graphite layer.
