Abstract
A ring vane nozzle for a gas turbine engine according to an exemplary aspect of the present disclosure includes a multiple of fixed turbine vanes between an inner vane ring and an outer vane ring and a multiple of rotational turbine vanes between the inner vane ring and the outer vane ring, each of the rotational turbine vanes rotatable about an axis of rotation.
Claims12
A full ring vane nozzle for a gas turbine engine comprising:
- an inner vane ring with a multiple of inner apertures;
- an outer vane ring with a multiple of outer apertures;
- a multiple of fixed turbine vanes between said inner vane ring and said outer vane ring;
- and
- a multiple of rotational turbine vanes having a pocket and a spindle section along an axis of rotation, said multiple of rotational turbine vanes mountable between said inner vane ring and said outer vane ring, each of said multiple of rotational turbine vanes rotatable about said axis of rotation defined by a respective pair of said multiple of inner apertures and said multiple of outer apertures, said multiple of inner apertures and said multiple of outer apertures each sized to receive one of said multiple of rotational turbine vanes at an angle with respect to said inner vane ring and said outer vane ring.
2 more elements
A method of assembling a vane nozzle for a gas turbine engine comprising:
- placing a multiple of fixed turbine vanes between an inner vane ring and an outer vane ring;
- receiving each of a multiple of rotational turbine vanes at an angle with respect to the inner vane ring and the outer vane ring, each of the multiple of rotational turbine vanes rotatable about an axis of rotation defined by a respective pair of a multiple of inner apertures within the inner vane ring and a multiple of outer apertures within the outer vane ring, the multiple of inner apertures and the multiple of outer apertures are larger than a pocket and a spindle section of each of the multiple of rotational turbine vanes.
