  • Controllable and programmable fluid flow modulation system
    Patent number: 4132500
    Abstract: This fluid valve is mounted in the hub of a circulation control helicopter otor to modulate the flow of air through the hub to the blowing slots on the leading and trailing edges of the blades. The valve independently controls the air pressure to the leading edge slots and trailing edge slots so as to vary the lift produced by each rotor blade as a function of its azimuth angle. The periodic waveforms of the air pressure provided to the leading edge slots and trailing edge slots in the blades are controlled by a combination of flow regulating cams and programming rings.
