EXPERIMENTAL INVESTIGATION OF WING LOAD CONTROL USING FLUIDIC DEVICES

A. Krzysiak, Institute of Aviation, Poland

A new concept of active flow control system based on blowing devices for the control of the aerodynamic load on aircraft wing was designed in Institute of Aviation and tested in IoA low speed wind tunnel. Experimental investigation showed, that using proposed fluidic devices up to 30% alleviation of maximum wing-root bending moment in a sudden-gust conditions can be achieved.
