Abstract

A gas turbine engine is provided comprising an outer casing and a plurality of circumferentially positioned vane segments. The outer casing is provided with a circumferential casing slot. The plurality of circumferentially positioned vane segments are coupled to the outer casing. Each vane segment comprises at least one vane airfoil, a radially inner shroud coupled to a first end of the airfoil, a radially outer shroud coupled to a second end of the airfoil, and a strongback fixedly coupled to axially spaced-apart portions of the outer shroud such that a gap is provided between the strongback and the outer shroud. The strongback may comprise axially spaced-apart first and second end portions received in the casing slot.

Claims (6)

1. A gas turbine engine comprising:

an outer casing with a circumferential casing slot;

a plurality of circumferentially positioned vane segments coupled to said outer casing, each vane segment comprising at least one vane airfoil, a radially inner shroud coupled to a first end of said airfoil, a radially outer shroud coupled to a second end of said airfoil, and a strongback fixedly coupled to said outer shroud; and

at least one tangential load block provided between two adjacent ones of said vane segments so as to transfer a tangential load from a first one of said vane segments to a second one of said vane segments;

wherein said strongback in each of said adjacent ones of said vane segments is provided with a corresponding recess for receiving said load block.

2. A gas turbine engine as set forth in claim 1 , wherein said strongback in said first vane segment further comprises an opening for receiving a portion of said load block.
