  • System for reducing thermal stresses in a leading edge of a high speed vehicle
    Patent number: 11260976
    Abstract: A hypersonic aircraft includes one or more leading edge assemblies that are designed to manage thermal loads experienced at the leading edges during high speed or hypersonic operation. The leading edge assembly includes a plurality of structural layers and a plurality compliant layers alternately stacked with each other to facilitate thermal expansion and movement between the plurality of structural layers, while also providing a thermal break between the plurality of structural layers.
    Type: Grant
    Filed: November 15, 2019
    Date of Patent: March 1, 2022
    Assignee: General Electric Company
    Inventors: William Dwight Gerstler, Nicholas William Rathay, Brian Magann Rush, Pazhayannur R Subramanian
