Abstract (en)
The blade (1) has at least one cooling channel (2), through which coolant flow is into a surrounding cavity. The cooling channel is made so that they amount of coolant flowing through it can be controlled, depending on the temperature. The channel has at least one throttle point (6) which is variable, depending on the temperature.
Abstract (de)
Die Erfindung betrifft eine Schaufel (1) mit mindestens einem Kühlkanal (2), der strömungsausgangsseitig in einen Umgebungsraum mündet, wobei der Kühlkanal (2) derart ausgebildet ist, dass eine den Kühlkanal (2) durchströmende Kühlmediummenge temperaturabhängig steuerbar ist. Insbesondere ist der Kühlkanal (2) mit mindestens einer variablen von der Temperatur (T) des Kühlmediums abhängigen Drosselstelle (6) versehen. <IMAGE>
