청구항

An anti-torque and yaw control system for a helicopter having a tail boom generally oriented perpendicular to the down wash of the helicopter main rotor when in the hovering mode, comprising: at least one linear nozzle having an opening extending longitudinally in said tail boom and disposed to discharge a jet of fluid tangentially to the surface of said tail boom so as to produce a thin layer of fluid flow; at least one means to produce at least one vortex intermediate the ends of said jet discharge from said at least one linear nozzle so as to intercep...
