Latest Patents

Cowburn's most recent patented inventions include the "Combustor Turbine Successive Dual Cooling" and the "Diffusion Mixer." The Combustor Turbine Successive Dual Cooling system revolutionizes how cooling air is managed within a turbine engine. This arrangement features a one-piece hot combustor wall along with front and rear cold combustor walls. Here, cooling air is pressurized and forced through perforations in the cold walls, impacting the annular sections of the hot combustor wall to ensure effective backside cooling while minimizing the air required. This innovative design directs the exhaust air to cool the turbine components without negatively influencing combustion emissions.

The Diffusion Mixer presents a sophisticated solution for industrial gas turbine engines. This premixer incorporates a diffuser ring assembly comprised of annular concentric rings, strategically designed to optimize airflow. Upstream of this assembly, a fuel manifold ring assembly corresponds to specific passageways, ensuring precise fuel distribution as the air moves through, thereby enhancing combustion efficiency.
