The storms that occurred in late March 2004 (with a relatively short return period of one or two years) clearly illustrate the vulnerability of urban areas to wind induced damaged. In various urban conurbations numerous trees and advertising hoardings failed, causing widespread disruption to the UK rail and road network. The wind borne debris present in these storms, due to both the failure of large items of street furniture/trees and unsecured items on the ground being lifted into the air, caused serious damage and destruction. For example, one person was killed as a result of wind-borne debris in Leicester and two died as a direct result of being hit by parts of a tree in Blundeston, near Lowestoft in Suffolk (BBC, 2004b). Unfortunately these events are not uncommon. For example as a result of the earlier storms of October 2000, with roughly the same return period, several people died and two were seriously injured. In the recent Birmingham Tornado much of the damage to buildings, and many of the injuries to people, occurred because of flying debris. Even in minor wind storms wind-borne debris can be a significant problem.This project aims to undertake a series of measurements on instrumented items of debris as they fly through the air. The data obtained from these tests will be used to improve and develop numerical models which will be of use to designers.

2004年3月下旬发生的风暴（相对较短的一两年重现期）清楚地说明了城市地区遭受风害的脆弱性。在各个城市大都市，许多树木和广告牌都倒塌了，对英国铁路和公路网络造成了大范围的破坏。由于大型街道设施/树木的损坏以及地面上不安全的物品被提升到空中，这些风暴中存在的风载碎片造成了严重的损坏和破坏。例如，莱斯特有 1 人因风载碎片而死亡，萨福克郡洛斯托夫特附近的布伦德斯顿则有两人直接被树的部分击中而死亡（BBC，2004b）。不幸的是，这些事件并不少见。例如，2000 年 10 月早些时候的风暴，其重现期大致相同，造成数人死亡、两人重伤。在最近的伯明翰龙卷风中，大部分建筑物受损和人员受伤都是由于飞扬的碎片造成的。即使在小风暴中，风载碎片也可能是一个严重的问题。该项目旨在对空中飞行的碎片进行一系列测量。从这些测试中获得的数据将用于改进和开发对设计人员有用的数值模型。
