Question 1 of 27070

The correct radial clearances between the rotor and the casing in a propulsion turbine are maintained by the turbine __________.

🔍 Key Concepts

• Radial vs. axial movement in a turbine rotor • The primary function of a thrust bearing versus journal bearings • How diaphragms and interstage packing are positioned relative to the rotor

💭 Think About

• Which component is specifically designed to control side-to-side (radial) clearance rather than end-to-end (axial) movement? • Think about which part actually surrounds the rotor and forms the stationary path for steam between stages. • Which items mainly support or locate the shaft, and which items mainly seal or direct steam flow?

✅ Before You Answer

• Identify which option directly affects radial clearance between rotor and casing, not axial position of the shaft. • Confirm which components are stationary parts of the turbine casing versus rotating shaft supports. • Eliminate any components whose main job is sealing or taking axial thrust, rather than setting radial clearances.
