In this work, a comparative study is performed for simulation of rotor in hovering flight with a 3D compressible Navier-Stokes solver using overlapped grid systems. The shape of rotor blade consists of optimized rotor blade planforms. Optimized blade planforms are designed considering high performance on hovering and forward flight. To show the verification of optimized rotor blade planforms, blade loading(C T , FM, C Q ) and the vortex behavior of optimized blade shape are compared with original blade shape.
