<p>A cooled component (60) for a gas turbine engine (10), for example a turbine rotor blade, is provided. The component has an internal cooling flow passage (70). Cooling air is passed through the internal cooling flow passage to remove heat from the component and thereby reduce its temperature. The cooling air is bled from the internal cooling passage after it has passed through a portion of the passage into an internal bleed flow passage (80). This bled air is then used in a seal. Thus, some of the cooling air that enters the internal cooling flow passage is used both to cool the component and to form a seal, for example with another component.</p> |
