Abstract
A rotor assembly is provided and includes a rotor impeller and rotor shaft. The rotor impeller includes a blade section and a forward section. The rotor shaft includes an aft section at which the rotor shaft terminates. The aft section is directly attached to the forward section of the rotor impeller. The blade section includes a converging blade configured to converge to a point with a minimized internal diameter (ID).
Claims21
A rotor assembly, comprising:
- a rotor impeller comprising a blade section and a forward section;
- and
- a rotor shaft comprising an aft section at which the rotor shaft terminates, the aft section being directly attached to the forward section of the rotor impeller,
- the blade section comprising an exit blade, which has an aft edge tapered forwardly with increasing radial height from a rotational axis of the rotor shaft, and a converging blade, which extends aft from the aft edge of the exit blade and which is configured to converge to a single and discontinous end defined along the rotational axis of the rotor shaft.

A rotor assembly, comprising:
- a one-piece rotor impeller comprising an exit blade, a converging blade and a forward section;
- and
- a rotor shaft that is rotatable about a rotational axis thereof and comprises an aft section at which the rotor shaft terminates, the aft section being directly attached to the forward section of the rotor impeller,
- the converging blade of the blade section being configured to converge with a non-linear profile to a single and discontinuous end defined along the rotational axis and aft of an aft edge of the exit blade that is tapered forwardly with increasing radial height from the rotational axis of the rotor shaft.
