Aero-TV: Making Good Planes Better - Micro VGs Offer Aerodynamic Enhancements

Vortex Generators Can Radically Improve Many Airframes VERY Cost-Effectively
While at the AOPA 2013 convention, ANN CEO and Editor-In-Chief, Jim Campbell had a chance to talk with Anni Brogan the President of Micro Aerodynamics Incorporated.
Micro Aerodynamics develops and produces vortex generators for various functions on numerous aircraft make and models. In this video, Brogan explains how the vortex generator works and how it does more than we may think it does.
It's common to see vortex generators on the leading edge of a wing and we usually associate this with reducing the stall speed. Brogan explains that stall speed adjustment through the use of vortex generators can be important, but they also can do more than that. Vortex generators can improve controllability and adjust the effectiveness of controls. For example, she points out that vortex generators applied to the rudder of a multiengine airplane can reduce the VMC speed.
Brogan's description of how the vortex generators work, how they are certified, and how they are tested and installed is interesting and informative. With this video you also get an informative mini-lesson in aerodynamics.

What a great spokesperson. Very articulate. A rare skill these days.

awesome lady

[@CessnaPilot99]

Please will micro aerodynamics offer them for the Grumman AA-5 series of aircraft. They say that since the grumman's have stall strips they're afraid to remove them because of liability concerns. They could be saving lives but instead are worried about litigation. She said in the video that she worked with piper to remove the stall strips.

I'd like to know the effects on fuel flow and speed at full power. I've heard it helps cruise but pushing extra pieces of equipment through the air takes energy. Are they saving more at full power than what it takes to push them through the air ?

[@vincenttremblay-dionne8343]

vortex generators on a wing is generally a sign of bad airfoil profile design

[@vincenttremblay-dionne8343]

only good for delaying stall and improve
flying security

Awesome

[@alexandervanwyk7669]

Agree, gorgious beautiful lady that talks with authority

[@nashdp]

Kind of like adding feathers to hard metal wings.

[@vincenttremblay-dionne8343]

no, feather block the reversal flow due to the adverse pressure gradient... VGs and MGVs re-energize the boundary layer by entrainement of the freestream into it
