Numerical Simulation of the Low Speed Aerodynamic Characteristics of a Set of Close-Coupled Canard Configurations
Abstract
A numerical simulation method simulating the leading edge shedding vortex in potential flow is used. Numerical simulation is conducted on an incompressible flow and at a large angle of attack as the flow passes a set of close-coupled canard configurations. Analysis shows that at a large angle of attack, with certain main wing and canard parameter selection and position configuration, the lift in the case of the canard configuration is higher than that of a single main wing; the main reason is because the canard can delay the breakdown of the main wing lift are negative pressure produced at the main wing surface by the canard shedding vortex, and the variation of the main flow field caused by the flow of the canard shedding vortex.
