Title: John L Winter: Innovator in Turbine Technology
Introduction
John L Winter is a notable inventor based in Derby, GB. He has made significant contributions to the field of turbine technology, holding 2 patents that showcase his innovative approach to cooling systems in gas turbine engines. His work is instrumental in enhancing the efficiency and performance of turbine blades.
Latest Patents
One of his latest patents focuses on the cooling of turbine blades. This invention facilitates the efficient use of high-pressure cooling air within a turbine rotor blade. The design features a triple-pass convoluted cooling air duct located in both the leading edge and mid-chord regions of the blade. These ducts are supplied by a common high-pressure inlet 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 blade's shroud is also equipped with cooling air passages, which are fed from the ends of the respective ducts. This innovative design allows air to exit through rows of film cooling holes, effectively cooling the concave flank of the aerofoil and removing heat from the thinner metal section at the trailing edge.
Another significant patent by Winter addresses gas turbine engines. In this invention, the cooling air from the nozzle guide vanes is discharged from one or both platforms to minimize leakage flow between the rotating and static components of the engine. Specifically, the cooling air is directed towards the engine casing, flowing through the clearance between the shroud of the engine casing and the shroud of the turbine blades. This arrangement effectively reduces gas leakage from the main gas stream and assists in lowering casing temperatures.
