    Abstract: 輕型運動類飛機除了可提供個人休閒運動使用之外,並可做為中短距離之交通工具,因此在各國通用
    航空位市場均已快速的成長。美國雖已於2004 年通過相關的法規,但對於輕型航空器的適墜性設計卻
    對於乘客安全性的影響。本文依據NASA AGATE 、ASTM 與FAR 所定義之掉落速度為參數,以
    MIL-STD-1290A 為安全邊界條件。本研究結果顯示,若飛機在不同速度撞擊地面時,以角度30° 可能
    In recent years, light sport aircraft which served not only for the purpose of personal recreation but also
    means of transportation vehicle for medium and short distance travel has made a rapid growth in the general
    aviation industry worldwide. FAA has established the regulations for this new category airplane in 2004.
    However, the crashworthiness requirements for this type of airplane have not been clearly specified. This
    study used finite element method to investigate the effect of impact angle and speed of the light sport aircraft
    (LSA) fuselage structure on passenger safety during a crash event. This work used sink speed defined by
    NASA AGATE, ASTM and FAR as parameters. The passenger compartment reducing rate defined by
    MIL-STD-1290A is used for a safety boundary condition. The results show the maximum cockpit reducing
    rate of the airplane impact angle is 30°. When the impact angle increases, owe to the engine mount and fire
    wall's reinforced structure, it can sustain the greater vertical drop speed. When the impact angle is about
    80°~90°, the maximum impact speed the fuselage can sustain is 33 mls. This work also completed the
    simulation of the safe and unsafe range for light sport aircraft at various impact angle and vertical drop speed
    during impact.
