FLOW CONTROL TECHNIQUES FOR TRANSPORT AIRCRAFT

摘要

A set of flow control approaches have been recently investigated for improved aerodynamic performance in a range of transport aircraft applications. Active Flow Control concepts are employed for reducing operational hazards during airplane ground maneuvering, alleviating trailing wakes for higher air traffic efficiency and improving takeoff and landing performance. Computational Fluid Dynamics has been extensively used to gain insight into complex flows subject to various modes of actuation and to develop promising techniques of flow control. The use of numerical simulations is especially important in scenarios involving powered systems, intricate vortex structures, separated flows, and active flow control devices, where alternative testing is extremely expensive and often impractical.
