Sam Bailey built three. You've got one, another is in Sam's home town
museum in Kansas, and Ken has the third. Ken put vortex generators on
his and likes the benefit he gets at high angles of attack.

Hey folks,
I have one of the Sam Bailey KR-1's and it does not have vortex generators.

Ken Cottle put them on his (Sam Bailey built) KR-1 and says they do a
good job. I can't remember if he said he lost anything on the top end
but I've heard you can expect a small amount of drag loss.

I'm still fairley new to all this, so I don't know if anyone has tried some on
their wings but I see klobs running them on the horizental staiblizers
even.Seems the low speed lift and handling are greatly improved.Thats just what
I want a good dose of. Any expermenters? Thanks ,joseph.
The vg's on our Navajo are used for a gross weight increase. In other

increase our t/o weight to 7368#. Our single engine roc is vastly improved

Has any thought of, or actually added, micro vortex generators to the wing

high speed flight, but significant improvement in low speed handling and a
reduced stall speed. Anyone have any thoughts?

Maybe I'm thinking too far ahead but has anyone have any KR2 experience with
vortex generators to lower stall speed?

VG's can help achieve different things, do enough reading and

I remember some of the EZ pilots using the Vortex generators. I couldn't
say for sure, but they seemed to place them between the Vertilons in front
of the ailerons to insure that they still had control on approach and
landing. I remember them saying that it helps speed up the air passing
Vortex generators for aviation are used to prevent what is called as boundary
layer separation, as Larry referred to. At high angles of attack the relative
wind strikes the leading edge at a more severe angle causing it to deflect up
and pass over the wing but with an increasing distance. The
I hope we can discuss subjects such as this at the
Gathering. Is the implication that we should all have
vortex generators as it may lower stall and landing
speeds? Would that make flying just a little bit
safer? Some of you guys out there have a tremendous
amount of knowledge. No need for all
would it be possible to get more air in the same area by putting vortex
generaters arround the inlet openings there-by smothing out turbulent air ?

Rick,
Perhaps you can explain the vortex generator to me. We have them on the
E-3, which is a modified Boeing 707. I don't see how they would help with
bugs or rain, as they are on the top of the wing, 3/4 of the way back from
the leading edge, and outboard of the elevators.
I'm not sure what
Long EZ owners started using them on the canard because it is a laminar flow
wing that looses lift when it gets contaminated with anything. Dirt, rain,
bugs, anything. A friend and EZ owner was barely able to keep his nose up
long enough to get it on the ground once, so he installed them and

Vortex generators prevent separation of the airflow from the wing surface

ailerons and flaps to

Mark, Actually I should have said that vortex
generators are effective on swept wings, such as the
vari-eze and longeze, velocity,etc. The airflow
seperates from the top of the wing more on swept wings
than on straight ones. Vortex generators are like
small gates or dams that make the airflow
Hi All
There seems to be a little confusion of the theory and practical use of
vortex generators. Here is my 2 cents worth.
A Vortex generator is a group of small tabs on the top or bottom of the
wing (also used on the vertical stab on some aircraft). They are small
