Active Flow Control Virtual Maneuvering System Applied to Conventional Airfoil

Autor: D. Dolgopyat, Avraham Seifert

Publikováno v: AIAA Journal. 57:72-89

This paper describes unconventional techniques to manipulate the pressures, forces, and moments acting on an airfoil without movable control surfaces. The method relies on active flow control (AFC)...

Suction and pulsed blowing for control of local wing-engine-slat-cut out flow separation: The INAFLOWT Project

Autor: Shay, Monat, Maayan, Possti, Ullah, Junaid, Avraham, Seifert

An experimental study on the application of active flow control (AFC) to a 1:8.4 scale model of a swept wing in a landing configuration was conducted. The wing is fitted with an Ultra High Bypass Ratio (UHBR) engine nacelle. The highly efficient UHBR
