re:sliding wings?

[jasonlee]

What is your aim?

What do you want to do , slow flight ?

There is a type of wing which was built and flight proven which
provided very slow flight like 22 mph...on a twin engine airplane.

This wing not straight adnd looks very different.It is a lot less
complicated than extensions, sliding sections etc.

this wing is called a Custer channel wing . Check it up on Google.

The plane was called a Brigadier if my old memory is right.

I am not against inventions and pushing the frontiers of knowledge but
why reinvent the wing when it was done more than 40 years ago ? :?

The original Baughman Brigadier had conventional wings, with two O-435s
in a pusher arrangement. Custer modified one into his Channel Wing. The
problem, of course was, "What happens if you are in such a slow flight
and an engine quits?"

The VF-173 had a worse potential problem, at any speed. The solution
was to mechanically couple the enginesso that iff one quit whatever
power
remained was still evenly divided bewteen the propellers. I'm not
clear
on why you'd want to engines, unless there were no enignes large
engough to drive both props.

There was also a single engine-prop-channel design.
