Would going with a forward swept wing design, with the same cord and length of the "A Wing", bring more air the the propeller and tail to increase range, power, or stability?

Consider the material available today to save additional weight needed to add torsional strength for this wing.

The 1970s, BD-5A can get 1200 miles on the original (A Wing) airfoil/wings. It is known for being unforgiving, stalling often on landings. The airfoil has had some design changes to make it more stable using the "B Wing" at the cost of 1/4th of the mileage. The wings are interchangeable in 15 minutes.

    $\begingroup$ The air doesn't flow along the wing quite like that. An airplane with a pusher prop wouldn't know the difference. Plus significant forward sweep requires a lot of extra torsional stiffness, hence weight. And you only do sweep in the first place for transonic performance. You just don't see swept wings more than a few degrees in subsonic a/c. So there's really no point. $\endgroup$

  • $\begingroup$ For subsonic there isn't really any point in sweep. Airliners have sweep b/c they are transonic. $\endgroup$
