Title: Innovations by Jonathan R Lilleker in Turbine Blade Cooling
Introduction
Jonathan R Lilleker is a notable inventor based in Leeds, GB. He has made significant contributions to the field of turbine technology, particularly in the cooling of turbine blades. His innovative designs aim to enhance the efficiency and performance of turbine systems.
Latest Patents
Jonathan holds a patent for the cooling of turbine blades. This invention features a triple-pass convoluted cooling air duct in both the leading edge and mid-chord regions of the turbine rotor blade. These ducts are supplied by a common high-pressure inlet located at the root of the blade. Additionally, the trailing edge region incorporates a single-pass duct that receives low-pressure cooling air from an inlet situated just beneath the blade platform. The design also includes cooling air passages in the shroud of the blade, which are fed from the ends of the respective ducts. Air from these ducts exits through rows of film cooling holes to effectively cool the concave flank of the aerofoil and through a row of holes in the trailing edge to dissipate heat from the thinner metal section in that area. Jonathan's innovative approach has led to the development of a highly efficient cooling system for turbine blades.
