Paper aiming at the research on the aerodynamic characteristics and flow field of the helicopter rotor by tip shape, the research on the aerodynamic shape performance of the double-swept lower reverse blade tip with sharpening will be carried out. CFD and experiment were used to evaluate the optimal tip shape, and to study the influence of the dihedral angle on the tip twin vortices.
