Title: Alan R Duly: Innovator in Turbine Technology

Introduction

Alan R Duly is a notable inventor based in Huntington, CT (US). He has made significant contributions to the field of turbine technology, holding a total of 2 patents. His work focuses on innovative solutions for measuring and sensing in high-temperature environments.

Latest Patents

Duly's latest patents include an "Electrode structure for a high temperature capacitance probe for sensing." This invention involves a probe designed for placement in the hot turbine section of a gas turbine engine. The probe features a housing containing two electrodes that extend through the turbine shroud into the tip clearance area of the turbine rotor. A voltage applied across the electrodes generates an electric field that is distorted as the turbine blades pass, producing a charge pulse at the probe's output. The design includes electrode conductors embedded in pins, which are secured by insulating rings, ensuring additional insulation and preventing contamination.

Another significant patent is the "Blade tip clearance measuring apparatus." This apparatus allows for the noncontact measurement of the clearance between the blade tips of a rotating turbine and the surrounding housing. The capacitance probe, placed in the housing wall, consists of two metallic conductors insulated from each other, forming the plates of a capacitor. The proximity of a blade tip alters the capacitance, and electronic circuitry measures this change to determine the clearance. The balanced type input design eliminates the need for a ground return path, enabling the use of a long sensor cable without compromising results.
