This paper contains the development procedure of small-scaled composite rotor blade for helicopter hingeless rotor system. Composite blade design is conducted by using CORDAS program developed by KARI and dynamic analysis is conducted by using Flightlab which is commercial software for helicopter analysis. Also the optimizing procedure of iterative design was described. The designed composite blades were manufactured after establishing the effective curing method. Through this research, the experiences of composite rotor blade development were accumulated and will be applied to the related research field.
