A SYSTEM FOR REPAIRING DAMAGED GAS TURBINE ENGINE AIRFOILS

摘要

A system for repairing damaged airfoils (28, 30) for gas turbine engines (10) includes a borescope with a plurality of rigid attachment tools (52). Each attachment tool (52) is individually shaped to access a leading edge (32) of the damaged airfoil (28) of a particular stage of the gas turbine engine (10). The attachment tools (52) enable repair of the damaged airfoils (28) without disassembling of the gas turbine engine (10).
