MATERIAL

Stage 2 HP turbine blade assembly

-

Wrought non-hardening nickel base alloy

General

The blade assembly blend limits are looked at by the serviceable structure of the blade. If you have many repaired blades in the same turbine assembly at or near the maximum repair limits or that have repair areas, they can effect the turbine efficiency and engine performance.

Price and availability - refer to IAE

The practices and processes referred to in this procedure by the TASK numbers are in the SPM.

      3. The minimum blend length to depth is 10 to 1.

      4. The maximum depth of the blend is 0.025 in. (0.64 mm) or 25 percent of the local platform thickness, whichever is less.

    2. SUBTASK 72-45-32-350-057 Identify the Repair

      1. Mark VRS3409 on the blade adjacent to the part number, if necessary.

      1. Make a permanent mark by the procedure given in the SPM TASK 70-09-00-400-501.
