Patents by Inventor Daniel Gillaugh

Daniel Gillaugh has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and system for repairing turbine airfoils
    Patent number: 11905845
    Abstract: The present disclosure is directed to a method and system for repairing a blade for a turbomachine that has been damaged due to foreign object impact. Machine learning algorithms are used to determine an amount of material to be removed from one or more damage locations and determine an amount of material addition to the damaged portion(s) and/or at other locations on the blade to keep the natural frequencies of the repaired blade within design limits during operation.
    Type: Grant
    Filed: October 3, 2022
    Date of Patent: February 20, 2024
    Assignee: United States of America as represented by the Secretary of the Air Force
    Inventors: Daniel Gillaugh, Alexander Kaszynski, Jeffrey Brown
  • Method and system for improving strain gauge to blade tip timing correlation
    Patent number: 11650130
    Abstract: The present disclosure is directed to a method and system to develop finite element (FE) models of as-manufactured turbomachinery blades using a combination of optical topography measurements, mesh morphing and strain gauge measurements. The method and system improves strain gauge to blade tip timing correlation using as-manufactured blade dimensions with finite element modeling.

  • Integrated, variable flux path electrical generator for turbine engines
    Patent number: 10897182
    Abstract: A power producing apparatus includes a stator portion having a stator ring disposed proximate a housing of a turbine engine. The stator potion further includes a plurality of coils. A rotor portion includes a rotor ring having a plurality of permanent magnets disposed coaxial to the plurality of coils, and the permanent magnets are oriented with alternating polarity. Individual or a plurality of coils are configured to be selectively moved axially with respect to the rotor ring.
