Latest Patents

One of his latest patents involves an engine shaft for a gas-turbine engine. This low-pressure turbine shaft features a fiber-composite plastic tube designed to take up and transmit torsional forces. The inner wall area of the tube includes fiber layers, while the outer wall area is equipped with fiber layers oriented to influence stiffness and damping characteristics. These layers are embedded in a high-temperature resistant plastic matrix. The load input element is an attachment flange made of fiber-composite plastic material, which is integrally formed on the fiber-composite plastic tube. Additionally, the load output element is a metallic driven protrusion that is inseparably connected to the fiber layers, transmitting the torsional forces. Alternatively, the load input element may be a metallic driving protrusion firmly connected to the fiber layers.

Another patent describes an engine shaft in the form of a fiber-composite plastic tube with metallic driving and driven protrusions. In this design, the connection to the metallic driven protrusion or the driving protrusion is made via an adapter formed onto the latter. Pylons extend beyond the circumferential area of the latter, guiding the fibers in accordance with their orientation in the fiber-composite material. This innovative design enables high torsional forces to be transmitted through a small connecting zone.
