AB  - The rotor blade made with composite material should be designed to fully sustain the bird-strike. This
analysis proved the structural integrity of the leading edge of the rotor blade made with composite material. To
apply the analysis of bird-strike, the debris of the bird was assumed to be fluid and applied as a Euler element
after the collision, since, there is a big difference among material property of the leading edge of the rotor blade,
solidity and property of matter of bird-strike. The analysis showed that the design of the rotor blade
pre-resistant structure had sufficient strength and safety factor for the impact of birds. The results of
the bird-strike analysis of composite blade are assessed to be sufficiently reliable and may be evaluated to
replace the test with various analysis conditions. Structural integrity of the rotor blade can be assessed by
applying various load conditions different current modelling methods in the future.
