Rotorcraft including an airframe having a fuselage extending between a
forward and an aft end and a powerplant producing high-pressure fluid.
The rotorcraft includes a rotor assembly rotatably mounted on the
airframe and having a plurality of rotor blades extending from a hub.
Each rotor blade has a base, a tip, a leading edge extending between the
base and tip, and a trailing edge extending between the base and tip
opposite the leading edge. Each rotor blade has a jet adjacent its
trailing edge in fluid communication with the powerplant by way of a
fluid path. Each jet is adjustable between an open position in which the
jet allows the high-pressure fluid from the power plant to pass through
the jet and out of the rotor blade and a closed position in which the jet
prevents the high-pressure fluid from passing through the jet and out of
the rotor blade.
