Latest Patents

One of his latest patents is a fixation device for the blading of a turbo-machine. This invention describes a fixation device that positions a plurality of blades longitudinally within a mounting groove. It features a mounting gap between adjacent blades, incorporating two collar halves that can be inserted into this gap. These collar halves are designed to enclose a gap space for a wedge element, which can be wedged to fix the collar halves in place within the mounting groove. The innovation is characterized by a connecting element on the wedge that interacts with a counter-contour on an adjacent blade, ensuring a secure shape-mated connection.

Another significant patent is a labyrinth seal for a rotating shaft. This invention involves sealing strips mortised into grooves between the rotor and stator of an axial turbo machine. The design includes relief grooves that maintain the axial stiffness of the rotor or stator. This is achieved through various methods, such as flat relief grooves or the use of elastic materials, which help distribute axial tension evenly along the rotor or stator section.
