Two documents discuss results of additional investigations of concept introduced in "Helicopter Tail-Boom Strakes" (LAR-13233). Essence of concept that strake or pair of strakes on side of tail boom facing retreating side of main rotor of helicopter perturbs flow in such way to increase aerodynamic pressure on that side, contributing force to thrust from tail rotor. Because of force, thrust required of tail rotor for yaw control reduced. Important advantage in low-speed flight, especially in sideward flight, in which tail-rotor thrust in absence of strake sometimes insufficient.
