Latest Patents

Kussmann holds a patent for a "System for suppressing vibration in turbomachine components." This invention discloses a system designed to mitigate vibration and noise in structures such as blades in turbomachinery. The system incorporates flexible piezoelectric patches that can be secured on or embedded in turbomachinery blades, which may include eight fan blades in one embodiment. Additionally, the system features a capacitor plate coupler and a power transfer apparatus, both of which can be arranged into a single assembly to transfer data and power. The design ensures that one part is attached to a fixed member while another part is connected to a rotatable member, maintaining an air gap between them. The system also includes a processor with 16 channels, where eight serve as sensor channels and the remaining eight as actuation channels. This processor collects and analyzes sensor signals, outputting corrective signals for vibration and noise suppression of the turbine blades.
