With a total of 2 patents, his work focuses on enhancing the efficiency and reliability of turbomachine components.
Latest Patents
Kerneis's latest patents include a method of repairing machined components such as turbomachine blades or blades of blisks. This method utilizes machining to repair a component workpiece from a known profile. It involves deforming the profile using a morphing method, which interpolates a cluster of points measured on the component. The process compares each zone of the component with elementary deformation configurations stored in a database. This innovative approach allows for precise repairs by addressing areas with excess or insufficient thickness.
Another significant patent is a part-holding device in a repairing method for a blade of a monobloc bladed disc in a turbo-machine. This device facilitates the electron-beam welding of a patch onto the blade along a junction plane. It includes a disc supporting device and an adjustable holding device that ensures the correct positioning of the blade and patch while allowing an electron beam to pass. This design is both simple and reliable, enhancing the repair process.
