VARIABLE FLOWPATH CASINGS FOR BLADE TIP CLEARANCE CONTROL - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240052752 titled 'VARIABLE FLOWPATH CASINGS FOR BLADE TIP CLEARANCE CONTROL

Simplified Explanation

The patent application describes variable flowpath casings for blade tip clearance control in a turbine engine.

  • An annular substrate with a first surface and a second surface is included, with the second surface being radially inward relative to the first surface.
  • An actuator structure is coupled to the second surface of the annular substrate.
  • A smart structure is cantilevered from the second surface of the annular substrate, including a support structure with a first region coupled to the second surface and a second region coupled to the actuator structure.
  • The smart structure has a radially inward surface defining a variable surface, allowing the support structure to move the variable surface in a radial direction.
      1. Potential Applications

Original Abstract Submitted

disclosed herein are example variable flowpath casings for blade tip clearance control. an example casing for a turbine engine includes an annular substrate extending along an axial direction, the annular substrate including a first surface and a second surface that is radially inward relative to the first surface; an actuator structure coupled to the second surface of the annular substrate; and a smart structure cantilevered from the second surface of the annular substrate, the smart structure including: a support structure, a first region of the support structure coupled to the second surface of the annular substrate, a second region of the support structure coupled to the actuator structure; and a radially inward surface defining a variable surface, the support structure to move the variable surface in a radial direction.
