Patents by Inventor Jon Robert DeLong

Jon Robert DeLong 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).

  • Bucket vibration damper system
    Patent number: 7731482
    Abstract: A damping system for a turbine bucket. The damping system includes a damper pocket with a variable tangential depth and a damper pin positional within the damper pocket.
    Type: Grant

  • Airfoil shape for a turbine bucket and turbine incorporating same
    Patent number: 7731483
    Abstract: Third stage turbine buckets have airfoil profiles substantially in accordance with Cartesian coordinate values of X, Y and Z? set forth Table I wherein X and Y values are in inches and the Z? values are non-dimensional values from 0 to 1 convertible to Z distances in inches by multiplying the Z? values by the height of the airfoil in inches and adding the radius of the airfoil base. The X and Y values are distances which, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z. The profile sections at each distance Z are joined smoothly to one another to form a complete airfoil shape. The X, Y and Z distances may be scalable as a function of the same constant or number to provide a scaled up or scaled down airfoil section for the bucket. The nominal airfoil given by the X, Y and Z distances lies within an envelope of +/?0.0.060 inches in directions normal to the surface of the airfoil.
