What is used to compensate for the increased possibility of blade vibration occurring with impulse turbine blading?

🔍 Key Concepts

• Impulse turbine blading and how steam hits the blades (pressure vs velocity change) • Common methods of controlling blade vibration in rotating machinery • Which options act directly on the blades themselves rather than elsewhere in the turbine

💭 Think About

• Look at each choice and ask: Does this method physically change how the blades move or interact to reduce vibration? • Which option is a common, mechanical way to tie or support blade tips against individual vibration? • Which choices deal with steam flow or sealing, and which deal with structural support of the blades?

✅ Before You Answer

• Identify which option clearly involves the blade tips rather than the casing or steam path. • Eliminate any choices that mainly affect steam sealing or pressure drop rather than blade stiffness/support. • Ask yourself which method is widely used on turbine blading to increase blade rigidity and reduce relative motion between adjacent blades.
