  • Strain amplification structure and synthetic jet actuator
    Patent number: 10153420
    Abstract: A strain amplification structure has a frame with a hexagonal structure incorporating a plurality of rigid beams that are connected to opposing end beams by a plurality of flexible joints. A piezoceramic actuator assembly is connected to the opposing end beams having a collar including an opening. A shaft providing an output is connected to the plurality of rigid beams with flexible joints and passes through the opening in the collar for non-interfering motion orthogonal to the actuator assembly.
    Type: Grant

    Date of Patent: December 11, 2018
    Assignee: The Boeing Company
    Inventors: Steven F. Griffin, Shawn Haar
  • Bellows synthetic jet
    Patent number: 9243622
    Abstract: A device for generating a synthetic jet is described. The device can include a flap, an actuator coupled to the flap and a chamber including an aperture. The flap forms a portion of the chamber. The flap is configured to oscillate in a flapping motion such that fluid is alternately drawn into the chamber via the aperture and expelled from the chamber via the aperture to form the synthetic jet. In some embodiments, multiple flaps can be used on a device to generate the synthetic jet.
