Hi All,
So after Prandtl convinced the world that elliptical lift distribution was the most efficient for a given span, he went on to explore his "bell shaped distribution" as the most efficient if structural weight is the fixed parameter. The flying wing guys (Horton and his fans like Al Bowers) jumped on board as it also could solve the adverse yaw problems with flying wings.
So here's my question: Since Part 103 ultralights are restricted in weight, and not span, it would seem logical that they employ the Prandtl lift distribution even in conventional configurations. And they may further benefit from a reduced need for vertical tail volume. Are there any examples out there that tried it?
