Abstract
A blade assembly for a gas turbine engine having an engine casing, with the blade assembly being configured to rotate about a rotational axis. The blade assembly having a blade, and at least one fin. The blade extending between a root and a tip, with the tip being spaced radially from the engine casing to define a space therebetween. The at least one fin extending radially with respect to the tip and into the space.
Claims18
A turbine engine comprising:
- an engine casing;
- and
- a blade assembly configured to rotate about a rotational axis, the blade assembly comprising:
- a blade having an outer wall extending between a root and a tip, and between a blade leading edge and a blade trailing edge;
- a tip platform provided along the tip of the blade, the tip platform being radially spaced from the engine casing to define a space therebetween;
- and
- a fin extending radially into and circumferentially within the space, the fin having:
- a wall extending radially and terminating at a distal end within the space with respect to the tip platform;
- and
- a plurality of circumferentially spaced fin projections, each fin projection extending axially outward from the wall and being formed as a hook.
