Title: Innovations by Inventor Sean Kelly

Introduction

Sean Kelly is a notable inventor based in Milton, Canada. He has made significant contributions to the field of gas turbine technology, holding a total of 4 patents. His work focuses on enhancing the performance and efficiency of gas turbine engines, particularly in the area of compressor rotors.

Latest Patents

Among his latest patents is a groundbreaking design for a compressor rotor aimed at supersonic flutter and resonant stress mitigation. This innovative gas turbine compressor for aircraft engines features a rotor with a variety of compressor blades arranged around a central hub. Each blade is designed with an airfoil that extends radially outward to a blade tip. Notably, a circumferential row of these blades incorporates two or more distinct blade types. At least one of these modified blades is engineered to generate varying shock patterns between adjacent blade types when operating in supersonic flow regimes. This design effectively mistunes the aerodynamic properties of the blades to optimize performance.

Another significant patent involves a mistuned fan for a gas turbine engine. This compressor rotor includes sets of blades with different airfoil thickness distributions. Each blade features a frequency modifier that creates a thickness differential compared to a baseline blade thickness. These frequency modifiers allow for distinct natural vibration frequencies for each blade, facilitating the modification of natural vibration frequency separation between adjacent blades within the compressor rotor.
