CMC LAMINATE AIRFOIL WITH PLY DROPS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18319586 titled 'CMC LAMINATE AIRFOIL WITH PLY DROPS

Simplified Explanation

- The patent application describes an airfoil design that uses a ceramic matrix composite (CMC) laminate material. - The airfoil section has an internal cavity and is made up of fiber plies embedded in a ceramic matrix. - The fiber plies include a skin ply on the outside and at least one inner ply that lines the skin ply. - The airfoil wall has fewer fiber plies at the leading and trailing ends compared to the pressure and suction sides. - The design aims to optimize the distribution of fiber plies for improved performance and efficiency of the airfoil.


Original Abstract Submitted

An airfoil includes an airfoil section that has an airfoil wall that circumscribes an internal airfoil cavity and defines leading and trailing ends and pressure and suction sides. The airfoil wall is formed of a ceramic matrix composite (CMC) laminate comprised of fiber plies disposed in a ceramic matrix. The fiber plies include a skin fiber ply that defines an exterior of the airfoil section and at least one inner fiber ply that lines the skin fiber ply. At least one inner fiber ply locally terminates at one of the leading end or the trailing end such that the airfoil wall has fewer of the fiber plies in the leading end or the trailing end than in each of the pressure side and the suction side.
