A Precision Impact Timing Control Method for Simulating Bird Strikes on Rotating Fan Blades in Turbofan Engines

Le résumé fourni par la source

Bird strikes on rotating fan blades constitute critical safety hazards in aviation, potentially inducing blade fracture, casing penetration, disk/shaft failure, and catastrophic engine malfunction, thereby severely compromising flight safety. This study introduces a novel experimental methodology implemented on a purpose-built test platform, enabling precise control of impact dynamics between high-speed rotating fan blades and avian projectiles. Through systematic optimization of the launch mechanism, impact timing synchronization protocols, and rotational speed control algorithms – coupled with integrated hardware-software synchronization and real-time blade phase prediction – the system achieves unmatched precision in simulating controlled bird strikes under realistic operational conditions. Comprehensive experimental validation confirms the platform’s efficacy and reliability, establishing a robust experimental foundation for the design and verification of foreign object damage (FOD) resistance and containment performance in turbofan engine fan assemblies and associated rotating components.
