Washout?

... I wnet looking for some "how it works" articles... with varying degrees of sucess. These were the more interesting http://en.wikipedia.org/wiki/Vortex_generator http://www.microaero.com/ http://www.zenithair.com/stolch801/d...vg-design.html Chris Heintz 701 VG page http://www.aerospaceweb.org/question...cs/q0009.shtml Interesting description... http://www.mitsubishi-motors.com/cor...004/16E_03.pdf Mitsubishi is using them on automobiles now! Interesting paper. http://www.avweb.com/news/reviews/182564-1.html The use of vortex generators is nothing new. First used in England, VGs have been used on transport jets for decades, and on bizjets since Bill Lear invented them. But historically they were used as an aerodynamic "band-aid" to deal with localized mach buffet problems at the high end of the airspeed envelope. MacDonnell Douglas engineers would routinely scoff at the VGs on Boeing jets and brag, "see, we don't need those things because we got our aerodynamics right in the first place." http://cas.umkc.edu/physics/sps/proj...ex/vortex.html Vortex rings - like smoke rings? Dolphins make air vortex rings in the water and play games with them. http://www.nasa.gov/centers/langley/.../Micro-VG.html NASA paper about micro VGs on the FLAPS (way cool) http://home1.gte.net/pjbemail/VortexGen.html VGs used to enhance top speed of ice skaters??? http://www.flxsys.com/Applications/A...x%20Generator/ ACTIVE (dynamic) VGs developed for the Air Force? http://www.physorg.com/news85159467.html Silly things are even being used under water... Richard -- (remove the X to email) Thanks, Richard, You really found a bunch of info and it looks like I have some reading ahead of me. BTW, at first glance, it really does look like vortex generators may be a real solution to a lot of problems including both the issue of stall charistics at the beginning of this thread and also the possibility of allowing higher wing loading for some LSA and Ultralights--where a reduction in wing size would make the weight limits a lot easier to meet.
