Any comment from aeronautical engineering types?
Have DG's results been independently verified?

Not sure about independent, but Jonker does the same thing for their
JS1's, and I've heard of experimental ASW20 mods to add one.

An air extractor system definitely makes the cockpit quieter and the
ventilation system
work better - that along improves pilot comfort and performance.

No the JS-1 vent is not the same as the Mandl extractor although
I was surprised to see the JS-1 vent didn't have a nice funnel to

Air into the cockpit must equal air out.
If you are ramming air into the cockpit and do not have a suitable exit,
where does it go? Predominantly out around the edges of the canopy and
worse still along through the wing roots and out the air brake box. In
'very bad' examples it is the

Hi Mike and others!
It wasn't only Wil Schuemann who experimented with an air outlet.
About 25 years ago Dick Buttler worked with Schleicher to fit
an air extractor to his ASW 22. Martin Heide put an air outlet
(similar to the Mandl device) on the undercarriage door of his

Hank Nixon built the ASW24/W27/W28/G29 kits now approved by Schleicher at his
shop in New Jersey. It can be found on USA Schleicher rep John Murray's website.

There have been other enhancements to gliders in the previous century
which offered theoretical improvements in performance.
There was a spontaneous outbreak of aileron fences in the mid seventies,
and serious consideration was given to fairings at the wing fuselage
