Title: Blown wings?
Post by: pb_guy on Feb 23, 2026, 05:40 AM
With the interest in the last topic, I thought I'd throw another topic in here. Another wrinkle - introducing an additional thrust vector in an interesting manner that alters the flow of air over the top of a wing, allowing a super-slow flight.

The initial video here:

And the follow-up new idea here with multiple motors along the LE of the wing:

Interesting - not dissimilar to the idea of bleeding some of the higher pressure on the lower surface of the wing onto the upper surface to delay flow separation, but using motors rather than "passive" structures

Thanks for sharing!

Very enlightening !!

That fellow has a very interesting channel - apart from his interesting blown wing clips he has carried out interesting experiments with ground effect models and water foils.

It is great when you run across some interesting ideas. I end up going down a lot of rabbit trails when I start looking at odd things.
