If I want to design an aircraft that can fly with high speed while loaded, which tail type should I choose.

The mission is to design an aircraft that can move a certain distance with high speed while carrying certain load.

    $\begingroup$ What does "high speed" mean? Supersonic? Transonic? Hypersonic? 200kts? $\endgroup$

    $\begingroup$ Every single aircraft can transfer some load some distance at some speed. Presumably. $\endgroup$

Lose the tail.

  1. Split brake-rudders will do the trick.

  2. You can also try and beat NASA and Boeing to the Active Flow Control tails.

  3. Or just settle for a T-tail.

The horizontal tail plate effectively increases the aspect ratio of the fin by virtue of the 'end plate' effect. The T-tail configuration is especially popular on gliders.

(Flight 1977—PDF) Early Boeing 757/767 designs featured T-tails to reduce drag.
