Distributed electric propulsion (DEP) aircraft makes full use of the aerodynamic/propulsion coupling effect to improve the aerodynamic efficiency of the aircraft, but the increase in the amount of power leads to strong interference between the propeller slipstream and the wing surface flow field, the complexity of aerodynamic analysis and design, and the rising costs of calculations. To improve the efficiency of aerodynamic design in the early design stage of DEP aircraft and reduce the development cost, a rapid evalution method of aerodynamic characteristics is proposed based on linear non-viscous vortex lattice method and actuator disk theory (VLM-ADT), VLM-unsteady VLM (VLM-UVLM) and Modified-VLM with viscosity correction. The aerodynamic characteristics of single wing, single propeller/wing coupling, X-57 wing (cruising, high lift state), and distributed propeller/wing coupling configuration were quickly evaluated. Compared with the Reyonlds-averaged Navier-Stokes (RANS) results, the lift coefficient and drag coefficient of single wing and single propeller/wing are in good agreement, and the maximum error does not exceed 8.2%; the pitch moment coefficient is in the same order of magnitude. The lift coefficients of the X-57 wing and the distributed propeller/wing are in good agreement with the RANS results, and the maximum error does not exceed 10%. The total drag coefficient of the X-57 wing and the distributed propeller/wing calculated by the VLM considering the viscosity correction is consistent with the trend of the RANS results. The distributed propeller slipstream increases the dynamic pressure of the wing, changes the local effective angle of attack of the wing, and changes the local lift-drag characteristics of the wing. Proposed method provides an effective method for the rapid evaluation of aerodynamic characteristics and rapid selection of aerodynamic layout schemes for distributed propeller aircraft in the early design stage.
