Abstract
The application of active flow control for high-lift multi-element wing sections is investigated. A computational fluid dynamics procedure is used to simulate the interactive flow in conjunction with distributed flow control. Favorable nonlinear interactions using flow control on a conventional wing section and an advanced airfoil lead to major aerodynamic performance improvements at representative takeoff and landing conditions. This study demonstrates that judicious application of flow control at select locations on the individual wing elements may lead to near inviscid lift levels in the linear lift range and substantial gains in maximum lift.
