Following bird strike damage to an aircraft turbofan, which mechanism increases uncontained engine failure risk?

💡 Explanation

Rotor imbalance resonance increases dramatically because the bird strike causes uneven mass distribution exacerbating vibration. Therefore, destructive interference damages nacelle integrity, rather than simple material fatigue or stall originating in aerodynamics.

• Which risk increases when wavelength division multiplexing (WDM) systems operate beyond their design channel count?
• Which consequence results when fuel injectors operate at a lean setting?
• Which consequence results when a low-resolution Hall effect sensor impacts position reporting in a robotic arm?
• Which consequence results when surface de-icing fails on turbine blades?
• Which consequence results when exceeding the slenderness ratio limit in supporting columns?
• Which mechanism causes thermal cracking in precision ground carbide cutting tools?
