Abstract
A blade for a gas turbine includes a tip cap and a tip squealer and passages for cooling fluid extending from a hollow space to the tip squealer. The tip squealer includes a cavity extending from the tip pocket into the tip squealer such that the cooling passage is divided into first and second portions with an exit hole in the cavity and an exit hole on the tip crown, respectively. In case of a blockage of the exit hole on the tip crown, cooling fluid can flow through the additional exit hole into the tip pocket and cool the squealer.
