METHOD FOR MANUFACTURING A COMPOSITE GUIDE VANE HAVING A METALLIC LEADING EDGE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240018873 titled 'METHOD FOR MANUFACTURING A COMPOSITE GUIDE VANE HAVING A METALLIC LEADING EDGE

Simplified Explanation

The abstract describes a method of manufacturing a composite guide vane with a metallic leading edge. The method involves receiving a layup of fiber-reinforced composite sheets impregnated with resin. A vane body is formed from the layup of sheets, which includes a mid portion for interacting with a fluid and an end portion. A metallic sheath is applied on part of the vane body to define the leading edge of the guide vane. The method also includes overmolding a head or a foot of the guide vane onto part of the vane body and onto part of the metallic sheath.

  • The method involves using fiber-reinforced composite sheets impregnated with resin to form a vane body.
  • A metallic sheath is applied to part of the vane body to create a leading edge for the guide vane.
  • The guide vane is further reinforced by overmolding a head or a foot onto the vane body and metallic sheath.

Potential applications of this technology:

  • Aerospace industry: The composite guide vane with a metallic leading edge can be used in aircraft engines to improve performance and durability.
  • Power generation: The guide vane can be utilized in gas turbines to enhance efficiency and reliability.
  • Marine industry: The technology can be applied in ship propulsion systems to optimize performance and reduce maintenance.

Problems solved by this technology:

  • Improved strength and durability: The combination of fiber-reinforced composite sheets and a metallic leading edge enhances the overall strength and durability of the guide vane.
  • Enhanced performance: The use of composite materials and a metallic leading edge can improve the aerodynamic efficiency and performance of the guide vane.
  • Reduced maintenance: The composite guide vane with a metallic leading edge is designed to withstand harsh operating conditions, reducing the need for frequent maintenance and replacement.

Benefits of this technology:

  • Lightweight design: The use of composite materials allows for a lighter guide vane, which can contribute to fuel efficiency and overall weight reduction.
  • Improved efficiency: The combination of composite materials and a metallic leading edge can enhance the aerodynamic efficiency of the guide vane, leading to improved overall system efficiency.
  • Increased durability: The composite guide vane with a metallic leading edge offers increased durability and resistance to wear and tear, resulting in longer service life and reduced maintenance costs.
