Patent abstract
A shroudless, air cooled gas turbine blade has an internal structure including load-carrying members that support the blade outer wall and divide the blade interior into cooling passages. The dimensions of the structure in particular the load-carrying members are chosen with respect to inward heat flow during operation to tend to reduce heat transfer from the outer wall to the load-carrying members and with respect to mass distribution in the structure to reduce centrifugal forces during operation.
