Q: I don't know them yet. Any reaction is welcome.
A: (From Kenneth M. Dorsett (Specialist, LMTAS Aerodynamic Stability & Control)) "I have some experience with such surfaces on high performance tactical aircraft; however, my comments should apply to a low-speed glider as well. Advantage: A large moment arm with respect to the CG makes these surfaces ideal lateral-directional controls. A great deal of control power can be generated by a relatively small surface. By staggering the surface aft (like Blohm & Voss did), you can generate a good deal of longitudinal control as well. These surfaces typically remain effective to very high angles of attack (AoA)."
Disadvantages:
Q: I don't know them yet. Any reaction is welcome.
A: (From Kenneth M. Dorsett (Specialist, LMTAS Aerodynamic Stability & Control)) "The primary disadvantage comes from structural integration problems. Tip mounted surfaces such as these are hard to keep stiff -- particularly on a thin-winged, high speed aircraft."
