A Mylar flyer plate, being launched by an electric gun, has been applied to explore the ballistic performance of a 2024 alloy Whipple shield consisting of a 1.0-mm-thick bumper and a 3.2-mm-thick rear wall with a standoff of 70 mm between them. In comparison with a spherical projectile, experimental results show that the polymer plate, having about one-fourth mass of an aluminum sphere, can penetrate the same Whipple at impact velocities of 3 km/s and 5 km/s. The ballistic limit curves (BLCs) of the Whipple are obtained in the velocity range from 3 km/s to 12 km/s using 0.25-mm-thick and 0.5-mm-thick Mylar flyers at normal and/or oblique impacts. Different from spherical projectile, the BLCs obtained by a flyer plate oscillate abruptly with impact velocity. The development of the BLC depends on both the spreading feature of the fragmented bumper sheet and the kinetic energy it carries. In normal impact condition, the BLC turns to go upward at the flyer/bumper shock pressures of 41 GPa, 71 GPa and 121 GPa, exactly corresponding to the occurrence of melting in bumper materials under the interactions among rebounded stress pulses, under the first releasing wave propagating through shock-compressed state, and under direct shock compression, respectively. Among the three melting mechanisms, the shock-induced melting produces the most widely spread debris cloud with the finest fragments.

由电动枪发射的 Mylar 飞板已被用于探索 2024 合金 Whipple 盾牌的弹道性能，该盾牌由 1.0 毫米厚的保险杠和 3.2 毫米厚的后壁组成，间隔为 70 毫米它们之间。与球形弹丸相比，实验结果表明，质量约为铝球四分之一的聚合物板可以以 3 km/s 和 5 km/s 的冲击速度穿透相同的 Whipple。Whipple 的弹道极限曲线 (BLC) 是在 3 公里/秒到 12 公里/秒的速度范围内使用 0.25 毫米厚和 0.5 毫米厚的聚酯薄膜在正常和/或倾斜撞击下获得的。与球形弹丸不同的是，由飞板获得的 BLC 会随着冲击速度突然振荡。BLC 的发展取决于破碎的保险杠板的扩展特性和它携带的动能。在正常冲击条件下，BLC 在 41 GPa、71 GPa 和 121 GPa 的飞轮/保险杠冲击压力下转向向上，正好对应于在第一次释放下，在回弹应力脉冲相互作用下保险杠材料发生熔化波分别通过冲击压缩状态和直接冲击压缩状态传播。在三种熔化机制中，冲击诱导熔化产生最广泛分布的碎片云和最细的碎片。恰好对应于在回弹应力脉冲相互作用下、在通过冲击压缩状态传播的第一次释放波和在直接冲击压缩下发生的保险杠材料熔化。在三种熔化机制中，冲击诱导熔化产生最广泛分布的碎片云和最细的碎片。恰好对应于在回弹应力脉冲相互作用下、在通过冲击压缩状态传播的第一次释放波和在直接冲击压缩下发生的保险杠材料熔化。在三种熔化机制中，冲击诱导熔化产生最广泛分布的碎片云和最细的碎片。
