So, I'm sitting on the can thinking about how the usual ways of blowing wings kind of suck.
The squirrel cage fans aren't efficient and rows of mini fans mean tons of parts.
Consider the rotary vane compressor. You could extend one of those axially the full length of the wing but with better efficiency than the squirrel cage ones.
Maybe.
AFAIK you can run the things at high RPMs just fine.

Might work well. Might not. Praise it or tear it up as you will.

Might work if you solve the problem of the rotor to flex in unison to the wings. Build a model, let us know.

If this works, your might...

Flex could be solved by making the blower in two or three shorter sections. Or I could just shorten the wing to make it stiffer since a blowing the whole wing multiplies the lift.

-look at VOLERIAN project...seems moore effective and silent!

I wonder how this compares to a normal propeller with the same power? To a ducted fan?

I read about that one a while back. Have they got a flying test model yet?

Certainly not as efficient as a single large prop, but maybe more efficient than other existing systems for USB lift.

-dr Sorokodum was achived >1000 N/kW thrust force on the simple fan,
and anihilation of drag with scheme like VOLERIAN suppose !

=much moore energyefficiant as propeller type...

So far I've only seen the volerain running as a slow speed mock-up.
They have calculations but I remain skeptical until I can see actual thrust measurements from it running at full speed.

-you are right,
but it is (today) only right way to build mass flying cars...
(LOW NOISE !!!)

=another > 100 Firms trying this via propellers thrusters are on one way street.

=hear bat in fly=ZERO wings noise...

Bat wings are made of stretchy skin and don't flap nearly as fast as VTOL thrusters would have to though.

I think you'll have trouble building an efficient vane pump for this. You may be better building a twin screw type blower. No need for any contact. Though you'll have fun carving the screws.

Yeah, it would have to be a two or three lobe blower that doesn't spiral.
