Introduction

David M Evans is a notable inventor based in Chula Vista, CA, who has made significant contributions to the field of gas turbine engine technology. With a total of 2 patents, his work focuses on enhancing the efficiency and longevity of turbine components.

Latest Patents

One of his latest patents is a turbine cooling system designed to improve cooling air delivery systems for gas turbine engines. This innovative system increases component life and enhances efficiencies by better utilizing the cooling air bled from the compressor section of the engine. The design directs a first flow of cooling air to the nozzle and shroud assembly while another portion is exited into an annular reservoir, improving the cooling of the rotor assembly and reducing the ingestion of hot power gases into the engine's internal portion. Additionally, a second flow of cooling air is directed through internal passages to further cool the rotor assembly.

Another significant patent by Evans is a changeable cooling control system for a turbine shroud and rotor. This system eliminates the need for major disassembly of engine components to change the flow rate of cooling air, which previously resulted in excessive costs and downtime. The innovative design allows for an elongate member to be accessed externally, enabling quick adjustments to the cooling flow rate without extensive engine disassembly.
