As I continue to explore the design space of my design in more and more detail, I've found something that's driving me a little bit crazy.
I have a low-aspect ratio, large chord wing. I have less wing dihedral than wing taper, so the top surface of the wing has "negative dihedral" -- the highest point is near the cockpit. I have a very restricted CG range due to being a flying wing. None of these things bother me, and none of them are going to change.
But it means that the highest point on the tank is four feet away from anywhere a person could stand to fuel up! And I'm not really willing to tell fuelers to climb up on the wing to fuel -- what am I, a high wing?
So... is anyone familiar with airplane designs that use a remote filling point, probably just a filler neck like a car uses? Obviously this neck would have to be placed like any fuel-carrying system -- clear of cabin, clear of firewall, well vented, etc. Other gotchas? Thinking about things like vibration (flexible neck?), filling rate (what diameter?), and all the other questions I don't even know to ask.
