Title: Innovations by Benjamin B Choi in Turbomachinery Vibration Suppression
Introduction
Benjamin B Choi is an accomplished inventor based in Broadview Heights, OH (US). He has made significant contributions to the field of turbomachinery through his innovative patent. His work focuses on enhancing the performance and reliability of turbomachinery components by addressing vibration and noise issues.
Latest Patents
Choi 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 of the coupler is attached to a fixed member while another part is connected to a rotatable member, maintaining an air gap between them. Furthermore, the system 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.
