Aerodynamic Geometry Optimization of Coaxial Rigid Rotors in Forward Flight
Proceedings of the Vertical Flight Society 74th Annual Forum, 2018Coaxial rigid rotor configuration provides helicopter higher forward flight speed than single-rotor configuration. Aiming at obtaining a coaxial-rotor blade shape with better aerodynamics in forward flight, a compressible RANS solver for aerodynamics simulations and an optimization method for blade design are established.
