Patents by Inventor Gerard D. Pelletier

Gerard D. Pelletier 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).

  • Hybrid exhaust component
    Patent number: 8997496
    Abstract: An exhaust includes a wall that has a first composite material having a first coefficient of thermal expansion and a second composite material having a second coefficient of the thermal expansion that is less than the first coefficient of thermal expansion.
    Type: Grant
    Filed: June 29, 2011
    Date of Patent: April 7, 2015
    Assignee: United Technologies Corporation
    Inventors: Gerard D. Pelletier, Charles P. Logan, Bryan William McEnerney, Jeffrey D. Haynes
  • Method for manufacturing ceramic matrix composite structures
    Patent number: 8859037
    Abstract: Methods are disclosed herein to fabricate high-strength ceramic matrix composite (CMC) structures by combining, in one example, pre-impregnated (prepreg) material with a pre-ceramic polymer. The prepreg is processed to a first density, and the densification is completed with repeated polymer infiltration and pyrolysis (PIP) cycles of the pre-ceramic polymer to fabricate a CMC structure. Advantageously, the present invention allows for fabrication of ceramic matrix composites more efficiently and to a larger scale than previously available.
    Type: Grant

  • Lightweight protector against micrometeoroids and orbital debris (MMOD) impact using foam substances
    Patent number: 7465500
    Abstract: Methods and apparatus are provided for a shield to protect a surface from the impact of hyper-velocity projectiles. The apparatus comprises a foam material that is configured to cover the surface to be protected and is attached directly to that surface. A coating material is typically disposed on the outer surface of the foam material and may penetrate the foam material to a predetermined depth. The foam material and the coating material are selected to form a composite having predetermined values of sonic velocity, toughness, and thermal conductivity. The composite of foam material and coating material can be significantly lighter in weight than a metal shield having equivalent protective characteristics.
