Title: David John Shepard: Innovator in Turbine Technology
Introduction
David John Shepard is a notable inventor based in Essex, GB. He has made significant contributions to the field of turbine technology, holding 2 patents that showcase his innovative approach to engineering challenges.
Latest Patents
One of his latest patents is a "Turbine blade monitoring" system. This invention involves a blade monitoring system and method for a turbine assembly comprising rotating blades. The system includes at least one sensor for transmitting a signal towards the rotating blades and detecting a time-varying return signal. It also features one or more processors configured to calculate the time derivative of the return signal, generate a phase variation signal, determine minima points within the phase variation signal, and measure the signal at these minima points. This process identifies data representative of respective minimum path lengths, allowing for the generation of a time series of data that represents the returned signal from individual blades as they pass the sensor.
Another significant patent is the "Foreign object debris detection system and method." This method aims to suppress the Jet Engine Modulation (JEM) clutter signal returns from compressor blades in data sampled by a system for Foreign Object Debris (FOD) detection in the air intake of a turbine assembly. The method involves identifying the start sample position and length in samples of a single complete shaft rotation and subtracting from a current rotation dataset the samples from a comparison rotation dataset corresponding to another complete single shaft rotation.
