🔍 Key Concepts

• Turbine rotor and blades – how blades are physically attached to the rotor or to each other • Meaning of tenon in mechanical/metal work (small projecting piece used for fastening) • What peening does to metal – deforming the end to lock something in place

💭 Think About

• Think about where a tenon would be located on turbine hardware: is it more likely to be part of a balancing process, a fastening method, or a thrust-control feature? • Ask yourself: when metal is peened, what physical change happens at the end of a pin or projection, and how would that help hold turbine parts together? • Consider which turbine components actually need small projections or pins that can have their ends deformed to keep parts from coming loose in service.

✅ Before You Answer

• Verify which turbine component typically has small projecting pins or lugs (tenons) designed to be deformed (peened) over • Confirm whether balancing or axial thrust control normally rely on deforming metal ends, or if those are usually achieved by other means (weights, thrust bearings, etc.) • Check technical descriptions or diagrams of turbine blade and shroud band attachment methods to see where tenons and peening are shown.
