Title: Walter Brehm: Innovator in Gas Turbine Technology
Introduction
Walter Brehm is a notable inventor based in Gebenstorf, Switzerland. He has made significant contributions to the field of gas turbine technology, holding a total of 2 patents. His work focuses on innovative sealing methods and fabrication techniques that enhance the performance and reliability of gas turbines.
Latest Patents
Brehm's latest patents include a leaf seal specifically designed for gas turbines. This leaf seal is engineered to effectively seal a shaft that rotates about an axis. It consists of multiple spaced-apart leaves arranged in a concentric circle around the axis, which are fixed in position through brazing. The leaves are designed with surfaces that are oriented essentially parallel to the axis. The brazing process involves intermediate spacers made of brazing foil, ensuring that a robust brazed joint is formed. The brazing temperature is optimized to prevent the penetration of liquid brazing alloy into the gaps between the leaves.
Another significant patent by Brehm outlines a method for fabricating, modifying, or repairing single crystal or directionally solidified articles. This method involves isothermally brazing two prefabricated parts using a specialized brazing material. Following this, an epitaxial or non-epitaxial layer is applied to the surface of the newly created article and the brazed joint through a laser metal forming process.
