Experimental Study on the Integrality of Mylar Flyer Driven by Electric Gun
电炮驱动Mylar膜飞片完整性实验研究

By means of technique of validating copper target,the effects of materials and structure of barrel as well as of the matching relationship between the sizes of bridge foil and barrel on the integrality of the flyer driven by electric gun were studied.The experimental results show that the materials of the barrel and whether the cutting edge preliminarily made or not have no noticeable influences on the integrality of the flyer in the condition of the flyer with velocity of several kilometers per second.When the size of barrel is a little smaller than that of the bridge foil,a full and circle flyer is gained.In this condition,the flatness of the flyer is good,which is demonstrated by the results measured with the technique of optical fiber probes.The results of the flatness and completion of the flyer show that electric gun is a good plane wave generator.
