David E. Jakstis 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).

  • Aluminum-copper alloys with improved strength
    Patent number: 10266933
    Abstract: Aluminum alloys are provided that can comprise boron and vanadium and high amounts of titanium and zirconium. The aluminum alloys described herein can exhibit superior tensile properties at both room temperature and elevated temperatures and still maintain desirable ductility. The aluminum alloys can be used in applications where resistance to fatigue and breakdown at elevated temperatures is desirable, which includes applications in the aerospace and aeronautical fields.
    Type: Grant
    Filed: August 27, 2013
    Date of Patent: April 23, 2019
    Assignee: SPIRIT AEROSYSTEMS, INC.
    Inventors: Rahbar Nasserrafi, David E. Jakstis, Gerald E. Hicks, Darrell Wade
  • Wrought and cast aluminum alloy with improved resistance to mechanical property degradation
    Patent number: 9347558
    Abstract: Aluminum-based alloys for casting or wrought processing having improved combinations of properties, including improved high temperature strength, are provided. The alloys generally comprise copper, magnesium, silver, and titanium, along with scandium and/or cobalt. Zirconium, zinc, and/or vanadium may also optionally be present in the alloy. When cobalt is present in the alloy, nickel may also optionally be present. Cast and wrought products, as well as methods of making the same using the alloys, are also disclosed.
