It's been awhile but I have been running a little design through my head the past month or so. Sorry if the write up is rough, please bear with me.

The basic concept is; high horsepower (300-400hp) turbo normalized water cooled single engine mated to the rear of an extremely efficient pressurized 6 place carbon composite fuselage in center line thrust fashion with the main wing spar passing below the rear bench seat.

Think scaled down learfan

With the only major difference being the intake would probably be a NACA duct and the cooling radiator would essentially be the vertical stab in a T tail configuration in order to get the horizontal stab outside of the prop diameter so we can get a cleaner less interrupted airflow.

Benefits of this design include
-clean jet like visibility
-far less noise as the propwash and turbulence is simply carried off into the airstream
-more efficient as the propwash is no longer destroying the airflow over the fuselage

very rough idea but the idea is to keep it light (1,800lbs empty/3,600lbs gross) and efficient with higher wing loading. One difficult issue I foresee is the wing design as the high wing loading will probably have to integrate some kind of electric flap system (hydraulics too heavy) in order to get stall speeds ~65knts


Thoughts?
