Numerical Study on Influence of Canard Height on Aeroelastic Behavior of Forward-Swept Wing

Abstract

Based on CFD/CSD loosely coupled numerical simulation method, the influence of canard height on the longitudinal aerodynamic characteristics and elastic deformation characteristics of forward-swept wing configuration model was calculated and analyzed. The results showed that the canard could effectively improve the aerodynamic characteristics of the forward-swept wing and delayed the stall angle of the main wing; the high-position canard wing can improve the aerodynamic characteristics and elastic deformation characteristics of the forward-swept wing better than the low-position canard wing; the detached vortex generated by the high-position canard wing can effectively improve the strength of the main wing vortex and improved wing root stall of forward swept wing. The results can provide some references for the design of forward-swept wing aircraft.
