US Patent 10280762 Multi-chamber platform cooling structures

A platform is disclosed. The platform may include an airfoil section with a cooling cavity and a platform. The platform may have various cooling features, such as a platform cooling apparatus. The platform cooling apparatus may have a cooling chamber forming a channel disposed at least partially through the platform and the platform cooling apparatus may have an inflow channel in fluidic communication with the chamber and the cooling cavity so that cooling air may travel from the cooling cavity of the blade airfoil section and into the platform cooling apparatus. Moreover, the platform cooling apparatus may have a cooling cover apparatus at least partially fluidically sealing the platform cooling apparatus.
