Coolant bridging line for a gas turbine, which coolant bridging line can be inserted into a hollow, cooled turbine blade

摘要

A coolant bridging line for a gas turbine having inner and outer sides which are separated by a wall, wherein the coolant bridging line extends from a first component of the gas turbine to a second component of the gas turbine is provided herein. The coolant bridging line for a gas turbine provides a further increase in the service life of the components of the gas turbine possible with a degree of efficiency which is nevertheless as high as possible. To this end, the coolant bridging line has means which change the heat transfer between and/or the flow conditions on the inner and outer sides.
