Abstract
Several life management methods of helicopter dynamic components were discussed, such as safe-life method, flaw-tolerance method, damage-tolerance method and fault-tolerance method. The origin and the current status about damage-tolerance method in life management both at home and abroad were presented. In comparison with the fixed wing aircraft, three main aspects, which can make the damage tolerance approach very difficult to apply in practice to every helicopter dynamic components, were discussed. Several key technical settlements when damage tolerance method was put in practice in life management of helicopter dynamic components were expounded emphatically. Finally, future needs for research were highlighted.
