Latest Patents

Stephen P Doherty, Jr. holds a patent for a "Control system for modulating bleed in response to engine usage." This control system operates a compressor bleed valve in a gas turbine engine to prevent compressor operation in the surge region. It determines engine stability by responding to various sensed engine parameters. The system calculates and stores engine parameters to estimate compressor performance relative to a stability limit indicative of surge operation. Additionally, it maintains a rolling average of compressor performance estimates for a predetermined number of engine flights. This rolling average reflects engine usage and associated degradation. The control system also determines a bias for the bleed valve based on calculated engine parameters and adjusts its operation to ensure stability limits are not exceeded.
