  • To meet the improvement of blade aerodynamic performance, blade-twist of coaxial rotors in hover design method was proposed.In this method, geometric installation angle was set for single rotor blade-twist, and the simulation results show reasonable blade-twist design can improve the rotor performance by 7.0%.In order to achieve hover coaxial rotor blade-twist design, the installation angle of upper and lower blade tips and rotors must be corrected, according to the blade tip vortex's impact, as well as coaxial rotor aerodynamic characteristics. Finally, the simulation results of coaxial rotors method show wing-twist lift is increased by 10.3% than that without twist of rectangular wing.
