This study aims to employ the Lattice Boltzmann Method (LBM) to simulate the aerodynamic characteristics of intermeshingrotor and coaxial-rotor systems during high-speed and stable forward flight. The research entails a comparative analysis of rotor thrust coefficients and induced velocity distributions between these two rotor systems across various forward flight speeds. The primary objective is to investigate the feasibility of achieving high-speed performance with the synchropter and to gain valuable insights into the aerodynamic features of intermeshing rotors during high-speed and stable forward flight. The consistent findings of this investigation demonstrate that, under identical input parameters, the intermeshing-rotor system maintains superior thrust performance compared to the coaxial-rotor system. In forward flight, the interaction between the left and right rotors in the intermeshing-rotor system exhibits nearly identical characteristics, contrasting with the non-uniform interference observed between the upper and lower rotors in the coaxial-rotor system. Moreover, as flight speed increases, rotor interference in both systems tends to diminish. Notably, during high-speed and stable forward flight, the intermeshing-rotor system's performance surpasses that of the coaxial-rotor system, suggesting that the synchropter holds the potential to emerge as a novel configuration for high-speed rotorcraft.
