Abstract
Abstract A deformable and expandable metal support formed from a thin sheet metal mounted between the stator or fixed vane and the wall of the complementary recess formed in the engine casing or shroud provides an interference fit for supporting the vane therein. A plurality of spaced elongated stamped-out depressions spaced chordwise relative to the vane and extending into the slot formed in the support structure carry a lead-in ramp and by virtue of press fitting therein said depressions are expanded laterally and deformed and when in the deformed condition provide a stiff zero clearance joint.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
116 words
Means for forming a joint for a fixed vane mounted in a shroud, said means including a sheet metal member having opposing side surfaces, a plurality of spaced elongated closed ended stamped-out depressions extending radially from one of said side surfaces and the other of said side surfaces being contiguous with the face of said fixed vane on one end, said disc having bass means defining a slot for receiving said one end of the fixed vane, the said one end together with said sheet metal member interference fitted into said slot whereby said depressions expand in a chordwise direction relative to the vane forming with bass means the stiff joint and absorbing the aerodynamic loading.
Claim 2
Dependent Claim
116 words
Means for forming a joint for a fixed vane mounted in a shroud, said means including a sheet metal member having opposing side surfaces, a plurality of spaced elongated closed ended stamped-out depressions extending radially from one of said side surfaces and the other of said side surfaces being contiguous with the face of said fixed vane on one end, said disc having bass means defining a slot for receiving said one end of the fixed vane, the said one end together with said sheet metal member interference fitted into said slot whereby said depressions expand in a chordwise direction relative to the vane forming with bass means the stiff joint and absorbing the aerodynamic loading.
Claim 3
Dependent Claim
32 words
A vane construction as claimed in claim 1 wherein the end of the depression is sized and shaped to define ramp surface to facilitate the insertion of the vane within the slot.
Claim 4
Dependent Claim
20 words
Means for forming a joint as claimed in claim 1 including means for securing said sheet metal to said vane.
Claim 5
Dependent Claim
19 words
A vane construction as claimed in claim 3 wherein said securing means includes rivets extending through said bass means.
