The vee-tail
A final variant of tailplane design is the vee-tail, illustrated in Fig. 10.9. The hinged trailing-edge control surfaces are moved differentially (one up and the other down) to provide a sideforce component like a rudder, and collectively (both up or down together) to provide a vertical component like a conventional tail. The claimed advantage of the vee-tail is that the number of surfaces is reduced, with consequential reductions in drag and weight. The F117A stealth fighter Fig. 6.34 uses a vee-tail which avoids the right-angles that cause large radar reflections.
