Title: Bilal Mokrani: Innovating Turbomachine Rotors with Piezoelectric Damping Technology
Introduction:
In the bustling city of Brussels, Belgium, Bilal Mokrani has made remarkable contributions to the field of turbomachinery with his invention of a piezoelectric damper system for axial turbomachine rotors. Through his work at Safran Aero Boosters SA, Mokrani has demonstrated a keen understanding of vibration-damping systems, leading to a patent that enhances the performance and resilience of turbomachinery.
The Patent: Piezoelectric Damper System for an Axial Turbomachine Rotor
Mokrani's groundbreaking patent revolves around a rotor for compressors or axial turbomachines, equipped with a vibration-damping system that incorporates piezoelectric transducers. These transducers are strategically distributed in a circular arrangement, connected to resonant electric circuits featuring resistors and coils.
Key Features and Benefits:
The innovative system developed by Mokrani enhances the stability and operation of turbomachine rotors in the presence of turning excitation. Here are some notable features and benefits of his invention:
1. Symmetrical Damping: Mokrani's system leverages the symmetrical characteristics of the rotor's modal shape, with diameters and orthogonal deformation waves. By employing a precise grouping of piezoelectric transducers that deform in the same way, Mokrani effectively dampens their vibrations with a pooled damping approach.
2. Capacitance Pooling: To optimize the pooling of capacitances and currents, the piezoelectric transducers are connected in parallel. This arrangement ensures that transducers with similar deformation behavior are effectively dampened by shared means.
3. Enhanced Resilience: With a high number of transducers deployed (quadruple the number of diameters in the mode), Mokrani's system maximizes the utilization of the rotor's symmetrical mode with diameters. This design choice enhances the overall resilience of the rotor and its ability to withstand vibrations.
