Title: Innovations by Donald Kendrick
Introduction
Donald Kendrick is an accomplished inventor based in Sammamish, WA (US). He holds 2 patents that showcase his expertise in advanced combustion technologies. His work primarily focuses on enhancing the efficiency and environmental performance of gas turbine engines.
Latest Patents
Kendrick's latest patents include a trapped vortex combustor designed for gas turbine engines. This innovative combustor features an annular housing with multiple inlet centerbodies arranged along a helical axis. The design incorporates a leading edge structure, opposing sidewalls, a pressurizable cavity, and a rear wall. The inlet centerbodies work in conjunction with adjacent structures to create a trapped vortex cavity combustion chamber. This chamber effectively mixes inlet fluid and burning fuel, resulting in hot combustion gases. The design achieves high combustion efficiencies with emissions of less than 10 ppm for oxides of nitrogen and carbon monoxide.
Another significant patent is the rotary ramjet engine with a flameholder extending to the running clearance at the engine casing's interior wall. This engine operates with a very low axial flow component and features a closely housed rotor and shaft. The design includes multiple ramjet combustors positioned at the rotor's periphery, along with spaced apart helical strakes extending toward the engine case's interior wall. Each ramjet inlet is equipped with a centerbody that facilitates the mixing of inlet fluid and burning fuel, producing hot combustion gases. The engine's design allows for the efficient extraction of kinetic energy or recovery of thermal energy.
