High-lift distributed active flow control system and method
David J. Manley
- 01 Nov 2005
TL;DR: In this article, a distributed active flow control (DAFC) system was proposed to maintain attached airflow over a highly cambered airfoil employed by an aircraft. But the authors did not specify the type of aircraft flight control surfaces (e.g., the aircraft wing, the tail, the flaps, the slats, the ailerons, and the like).
