Abstract: Disclosed ia an anti-torque and yaw control system for rotary wing aircraft employing tip driven rotor blades. The rotor blades are driven by a turbine drive ring powered by high velocity fluid. The drive ring is enclosed in a shroud and fluid passing through the turbine ring is collected in a ducted fan axially alligned tangentially with the dirve ring. The ducted fan is also tip driven by fluid from the main drive fluid supply. Alternative arrangements for varying the thrust of the ducted fan are shown. A jet thruster cooperating with the drive system is used for yaw control.
