Title: Innovations of John C Szillat
Introduction
John C Szillat is a notable inventor based in Rockville, Connecticut, who has made significant contributions to the field of gas turbine technology. With a total of four patents to his name, Szillat has developed innovative solutions that enhance the performance and reliability of gas turbine engines.
Latest Patents
One of Szillat's latest patents is a "Starting fuel control system for a staged combustor." This invention includes apparatus and methods to operate the combustor during pilot operation, staged operation, and the transition between these two modes. The design features a fuel control system with a switch that has built-in hysteresis to determine the transition points between operating modes. In one embodiment, the combustor switches from pilot to staged operation at a thrust level greater than the thrust level at which it switches back. This innovation limits changes in fuel flows during transitions to prevent combustor fuel spikes and blowouts. Additionally, during engine starts, the fuel lines to the main combustor are pre-filled to enhance responsiveness during transitions.
Another significant patent is for "Non-recoverable surge and blowout detection in gas turbine engines." This invention provides indications of non-recoverable compressor surge and blowout by sensing compressor pressure, temperature, and speed. It compares exhaust temperature with stored values and successive values based on instantaneous compressor speed and its derivative. The blowout indication is provided at timed intervals that reset if surge indications are present.
