  • Ceramic matrix composite turbine engine vane
    Patent number: 8210803
    Abstract: A vane has an airfoil shell and a spar within the shell. The vane has an outboard shroud at an outboard end of the shell and an inboard platform at an inboard end of the shell. The shell includes a region having a coefficient of thermal expansion (CTE) varying with depth.
    Type: Grant
    Filed: June 28, 2007
    Date of Patent: July 3, 2012
    Assignee: United Technologies Corporation
    Inventors: Jeffery R. Schaff, Jun Shi
  • Ceramic matrix composite turbine engine vane
    Patent number: 8206098
    Abstract: A vane has an airfoil shell and a spar within the shell. The vane has an outboard shroud at an outboard end of the shell and an inboard platform at an inboard end of the shell. The shell includes a region having a depth-wise coefficient of thermal expansion and a second coefficient of thermal expansion transverse thereto, the depth-wise coefficient of thermal expansion being greater than the second coefficient of thermal expansion.

  • METHOD AND APPARATUS FOR MONITORING STRUCTURAL HEALTH
    Publication number: 20100161244
    Abstract: A method includes performing a first damage prediction with a computational model using at least data from a first multitude of damage sensors on a structure, performing a second damage prediction with the computational model using at least data from a second multitude of load sensors associated with the structure, and selectively performing a damage monitoring action in response to the first damage prediction and the second damage prediction to determine a structural health A system includes a computing device configured to perform a first damage prediction using at least data from a multitude of damage sensors on a structure, a second damage predication using at least data from a multitude of load sensors associated with the structure, so as to selectively perform a damage monitoring action in response to the first damage prediction and the second damage prediction to determine a structural health of the structure.
