摘要
This paper is focused on the numerical evaluation of Active Flow Control (AFC) applied to the deflected aileron of the NASA High-Lift Common Research Model (CRM-HL) wind tunnel model in order to enhance aerodynamic performance during high-lift operations. Computational evaluations are performed on a representative high-lift configuration in the takeoff setting for a set of aileron deflections, and at relevant flow conditions. The computational results indicate that the aerodynamic performance improvements due to AFC obtained for the CRM-HL are consistent with those predicted on other airplane configurations. The predicted gains in L/D due to the aileron AFC actuation are smaller than those obtained in another study of a smaller (single aisle) aircraft because the CRM configuration has a higher leading-edge sweep angle and a different aileron size. The trends from the numerical results are consistent with the experimental data presented in a companion paper.
