Hello everyone,

I am a new member and would like to introduce myself here in Aircraft design as it is what interests me. I am a pilot (glider and aircrafts 500 hours in each), a designer by trade, an organic farmer by need and an aircraft designer by love. My daily work allows me to think a lot and I can design a bit in the evening and think about it all day before making modifications or before exploring a new ideas.

I am very interested in high L/D aircrafts as air-workhorses, and I am designing a 160hp single with an L/D of 28, and a span of 14meters. It should carry a payload of 350kg for 4500 km.

I am struggling with airfoils and wing loading, and have recently been quite excited by older semi laminar airfoils like the 12% Hawker Tempest and the Eppler 231. Both have very low moments and low drag at low Cl.

Has anyone here thought about those airfoils before?

best regards everyone
