Abstract
A turbomachine having an engine centerline and a first rotor. The first rotor having a first annular drum and being connected to a first plurality of blades. At least one blade of the first plurality of blades having a blade root, a blade tip, a first arm, a second arm and a first seal. The first arm extending from the blade root and having a radial retention hook. The second arm extending from the blade tip.
Claims20
A turbomachine having an engine centerline, comprising:
- a first rotor having a first annular drum, the rotor being rotatable about a rotational axis;
- and
- a first plurality of blades coupled to the first rotor, with at least one blade of the first plurality of blades comprising:
- an outer wall extending between a blade root and a blade tip, and between a blade leading edge and a blade trailing edge;
- a first arm extending from the blade root and having a first radial retention hook for radially retaining the at least one blade to the first rotor;
- a second arm extending radially and axially from blade tip, with respect to the rotational axis;
- and
- a first seal provided along the second arm and extending radially away from the second arm, with respect to the rotational axis, with at least a portion of the first seal being provided at least one of axially upstream of the blade leading edge or axially downstream of the blade trailing edge.
