摘　　要：激光驱动微小碎片装置是地面模拟微小空间碎片对航天器超高速碰撞的重要设备,其模拟碎片的速度和整体性是两个最关键的性能参数。文中从驱动设备的原理出发,介绍了激光性能参数、飞片靶约束层及烧蚀涂层对碎片速度和整体性的影响,并介绍了约束层和烧蚀涂层厚度设计方法及选材范围。近期的试验研究采用单膜结构飞片靶,试验可以将7μm厚、直径1 mm的铝膜驱动到8．3 km/s。Laser-driven flyer device is one of the important ground systems to simulate hypervelocity impact of space debris to spacecraft. Velocity and integrity of the flyer are the key parameters for the device. The effects on the velocity and integrity of flyer induced by laser parameters, substrate and ablation layer of flyer targets were discussed. Thickness design and rang of material selection for the substrate and ablation layer of flyer target were also discussed. In recent study, 7μm thickness, 1 mm diameter aluminum flyer can be launched to 8.3km/s, and the structure of flyer target is single-layered.
