Title: John Robert Fagan, Jr: Innovator in Magnetic Bearings for Compressor Stability Control

Introduction

John Robert Fagan, Jr. is an accomplished inventor based in Zionsville, IN (US). He has made significant contributions to the field of gas turbine engine technology. His innovative work focuses on enhancing the performance of compressors through advanced magnetic bearing systems.

Latest Patents

Fagan holds a patent for "Magnetic bearings as actuation for active compressor stability control." This integrated system is designed to control the positioning of a rotating rotor within a compressor. The technology aims to improve the performance of gas turbine engines by utilizing magnetic bearings to support and position the rotor within high-speed turbomachines. During compressor operation, these magnetic bearings non-axially position the rotor relative to the compressor housing, providing essential compressor instability control. This non-axial displacement creates a local disturbance in the fluid flow field, which alters the dynamics of the aerodynamic system and effectively displaces the compressor surge line. Fagan's patent represents a significant advancement in compressor technology.
