Rotor blade injuries are an inherent hazard of helicopter operations. To determine the recent incidence of rotor blade injuries in the U.S. Army, a review of accident records (1972-91) was conducted. Crash-related injuries were not included. During the study period, there were 24 blade strike injuries (12 involving the main rotor), 11 (46%) of which were fatal. Comparison with previous reports indicates a lower rotor blade injury rate in the last decade than in any previous period. The head was injured most frequently (65%), followed by the chest (17%) and abdomen (7%). Protective helmets helped to reduce injury in several instances. Flight crew comprised 49% of the victims, passengers 29%, ground crew 14%, and bystanders 8%. Helicopter crews must maintain situational awareness when around turning blades--professional training alone does not guarantee protection from rotor blade injury.
旋翼叶片损伤是直升机作业中固有的危险。为确定美国陆军近期旋翼叶片损伤的发生率，对事故记录（1972 - 1991年）进行了回顾。与坠机相关的损伤不包括在内。在研究期间，有24起叶片撞击损伤（12起涉及主旋翼），其中11起（46%）是致命的。与之前的报告相比，表明过去十年中旋翼叶片损伤率低于以往任何时期。头部受伤最为常见（65%），其次是胸部（17%）和腹部（7%）。在若干情况下，防护头盔有助于减少损伤。受害者中飞行机组人员占49%，乘客占29%，地勤人员占14%，旁观者占8%。直升机机组人员在旋转叶片附近时必须保持对周围情况的警觉——仅靠专业训练并不能保证免受旋翼叶片损伤。
