由于箭飞行的动态特性，测量箭的弹道性能，如箭在撞击时的速度、总飞行时间和箭杆振荡是具有挑战性的。随着射击距离的增加，这项挑战变得越来越困难。这也是极大的兴趣，弓猎人了解弹道性能的箭，包括狩猎宽头。一个小型化的传感数据采集系统，位于箭尖，设计承受发射和撞击时的高加速度，使箭在飞行中的弹道精确测量。通过连续记录箭在飞行中的阻力，该系统能够测量箭在向下飞行时的弹道性能。作者还建造了一个连接到传感系统外壳的适配器，以便在狩猎宽头上进行比较弹道测试。在这里，我们提出了使用传感系统进行初步测试的两个商业上可用的宽头在拍摄距离约45米的结果。
Measuring an arrow's ballistic performance such as arrow velocity on impact, total time of flight and arrow shaft oscillation is challenging because of the dynamic nature of arrow flight. This challenge becomes increasingly difficult as the distance of the shot increases. It is also of great interest to bowhunters to understand the ballistic performance of arrows that include hunting broadheads. A miniaturized, sensory data acquisition system, located in the arrow tip and engineered to withstand the high accelerations experienced at launch and impact, enables the precise measurement of arrow ballistics in flight. By continuously recording arrow drag in flight, the system enables measurement of the ballistic performance of an arrow as it travels downrange. The authors have also built an adapter that is connected to the housing of the sensing system to allow for comparative ballistic tests to be performed on hunting broadheads. Here, we present results obtained using the sensing system to perform initial testing on two commercially available broadheads at shot distances of approximately 45 m.
