This paper presents the design of helicopter tail rotor composite blade. The requirements which. govern the design of the tail rotor are: strength, power efficiency, low weight, avoidance of vibrations. and additional noise, and easy controllability. The design of the tail rotor is expressed by the main. design parameters: diameter, tip speed, solidity, number of blades. Length of machine, ground. clearence and weight considerations will all favour the small antitorque rotor. Avoidance of. resonance frequencies may affect the choice of tip speed.
