Hi, folks.  I'm the one that wrote about a lift system using driven air and a
stationary wing.  I've gotten some responses, but I want to make sure you all
know what I'm talking about.  So here goes:

Below is a super-sorry rendition of a airfoil, with an duct coming out of the
upper leading-edge.  High-speed air (from some central centrifugal blower or
something) shoots out of this duct, and over the wing.

Lift is produced by the resulting static-pressure difference between the top of
the wing (with the driven air flowing over it) and the bottom of the wing,
where the air is still.

Thrust is produced, too, becuase the air is being blown BACK, (action-reaction,
ya know).

Once you got going, you could retract the duct into the leading edge of the
wing, and blow the air out some ducts in the very back, for thrust only (since
you'll be getting lift naturally becuase you're moving)


             ------      LOW PRESSURE
           /   <- air comes out here   Flows out t
 leading /      ------------------------------\    h
  edge /                     / \                 \   i
       \                      |        ------>      \   s
         \                    |lift    thrust          \  w
           \--------------------------------------------- \  a
                        HIGH PRESSURE                          y
 
So that's it.

Please tell me whatever you think about it (if I'm a genius, an idiot, a
plagariser, whatever..)

Thanks all,

CM
