Hi James
Good thinking 99.
That's exactly what Schleicher has done already with their latest
generation of gliders.
To get the ASG 29 to 600 kg you need to put 35 litres of water in
the main fuselage tank
unless you are an extremely heavy pilot. The alternative is to opt
for an engine.
A second fuselage tank is located in the fin just for C of G adjustments.
Kind regards

And you lose all baggage compartment space. By the time you fit in
the wheel oxygen bottle, batteries, control runs and bellcranks,
linkages etc there is not much volume left in the fuselage except in
the tailboom and that causes C of G problems. Many years ago I
designed an extended range fuselage tank for the TOP in the Ventus A
fuselage. The tank fits behind the wheel box in front of the rear
part of the steel tube frame. It is installed through the luggage
compartment and we managed to get a whole 11 litres in it. You could
possible get a second tank in above it but it is difficult.
If buckypaper really results in significantly lighter structures you
still have a problem.
