目的 向航空工业部门提供伞兵伞开伞过载生理允许值。方法 进行了不同飞行速度下的121人次真人试跳,70例跳伞员的问卷调查,以及8具尸体头颈部加载试验并建立了头颈部数学模型。结果与结论 提出在飞机表速325km/h,高度800m,用伞兵-4降落伞,开伞过载生理允许值不大于10.79±1.64G。
Purpose To provide the aviation industry with the paratrooper parachute overload allowance. Methods A total of 121 human-to-human jumps at different flight speeds, 70 parachutists’ questionnaires and 8 heads and shoulders loading tests were conducted and a mathematical model of head and neck was established. Results and Conclusions The parachute parachute -4 parachute and parachute overload allowance is not more than 10.79 ± 1.64G at the surface speed of 325km / h and the altitude of 800m.
