Which outcome increases thermal stress in jet turbine blades because of rapid acceleration?

💡 Explanation

Tip clearance rub greatly increases thermal stress. because unequal expansion causes contact; the ablation increases operational temperature, therefore decreasing component service life, rather than vibration which would generally occur over longer time scales.

• Which outcome occurs when a large inductive load energizes near power grid resonance resulting in amplified voltage oscillations?
• Which consequence results when isothermal forging induces excessive quenching?
• Which outcome occurs when a turbocharger malfunctions, causing excessive air intake in a modern gasoline engine?
• Which risk distinctly increases in three-phase power systems when a single-pole circuit breaker trips under load?
• Which outcome occurs when a screw pump in a refrigerant system operates with excessive superheat at suction?
• Which consequence results when a PLC timing delay accumulates excessively in a robotic arc welding cell?
