Which part of a propulsion system aids in the radial positioning of turbine components?

• A. Mounting brackets
• B. Thrust washers
• C. Journal bearings
• D. Clamping plates

Answer: (C)

The radial positioning of turbine components is primarily achieved through journal bearings. These bearings support the rotating shaft and allow for smooth movement while maintaining precise alignment. In a propulsion system, journal bearings provide a crucial function by minimizing friction and wear between the rotating components and the stationary surfaces. This ensures that the turbine runs efficiently and reliably, as any misalignment can lead to operational failures or decreased performance. While mounting brackets, thrust washers, and clamping plates serve important roles in maintaining structural integrity and supporting various components within the propulsion system, they do not specifically contribute to the radial positioning of turbine components in the same way that journal bearings do.
