TURBOMACHINERY WITH HIGH RELATIVE VELOCITY

摘要

The present disclosure relates generally to turbomachinery in which a rotating component is disposed adjacent a counter-rotating component in order to achieve a relative rotational velocity that is higher than would be achieved with a rotating component disposed adjacent to a stationary component.

主权项

1. A turbomachine, comprising:
at least one rotor stage operative to rotate about an axis in a first direction, each of the at least one rotor stage comprising a plurality of rotor blades; an outer ring case operative to rotate about the axis in a second direction opposite the first direction, the outer ring case including an inner surface; wherein the at least one rotor stage is at least partially disposed within the outer ring case; and at least one counter-rotating stage disposed on the inner surface of the outer ring case, each of the at least one counter-rotating stages comprising a plurality of airfoils disposed adjacent respective ones of the plurality of rotor blades.
