| Abstract: | This paper gave aerodynamic numerical simulations for a tail cept rotor anti - torque of NOTAR helicopters that based on embedding boom. Simulating use the commercial CFD software Fluent, this article boom of a kind of new con-a cross-flow fan into tail analyzed aerodynamic influ-ence of cross - flow fan＇s structural parameters on tail boom of NOTAR helicopters. From the resuhs of the CFD work, we want to find out the perfect structural parameters of rotor anti - torque system that can guide us to design a better new concept rotor anti-torque system than before. |
