Abstract

In order to study the combined damage of blast and fragments on helicopter rotor, the rotor structure was analyzed; The damage model of the rotor structure by blast wave and fragments was built. The effects of explosive charge, explosion position, perforation density on damage of rotor were calculated. The results show that the most dangerous section of rotor is in the root of rotor. The stress of the rotor root is maximum when explosion horizontal position is at the centerline of wingspan: The damage of rotor decreases with the increasing of explosion vertical position: The damage of rotor increases with the increasing of explosive charge and perforation density; The critical damage curves of rotor are drawn.

Key words： blast waves; fragmonts; helicopter rotor; damage of rotor
