Abstract
A turbine engine having counter-rotating rotors comprising a first rotor, rotating in a first rotational direction, defining a first rotor set of blades axially spaced to define a gap, and a second rotor, rotating in a second rotational direction counter the first rotational direction. The second rotor further including a second set of blades received within the gap of the first rotor. A plurality of fluid passages is formed in the first rotor with an outlet facing the gap.
Claims20
A counter-rotating turbine engine defining an engine centerline and comprising:
- a first rotor, rotating about a rotational axis in a first rotational direction, and having a body and at least two first pluralities of circumferentially arranged blades extending radially from the body with respect to the engine centerline, the at least two first pluralities of circumferentially arranged blade being spaced axially, with respect to the engine centerline, from one another to define a gap therebetween;
- a second rotor, rotating in a second rotational direction with respect to the rotational axis, counter to the first rotational direction, and having a second plurality of circumferentially arranged blades provided within the gap of the first rotor;
- and
- a plurality of fluid passages formed in the body of the first rotor with each fluid passage of the plurality of fluid passages extending continuously between an inlet directly fluidly coupled to a portion of the counter-rotating turbine engine exterior of the first rotor and an outlet facing the gap, with each fluid passage defining a passage centerline oriented to redirect a fluid flow within a respective fluid passage from the first rotational direction toward the second rotational direction.
