How vibration fatigue analysis for eVTOL and VTOL structures works: rotor harmonics, stress power spectral density, Dirlik and rainflow, damping, ground vibration testing and FE model updating with MAC gates, and where AI helps.
How electric motor NVH simulation links slot and pole force orders, PWM switching harmonics, torque ripple, stator and mount modes and the airframe path to the cabin, and where AI helps.
How eVTOL noise simulation works: rotor tones and broadband sound, interaction sources, the FW-H analogy on CFD, what regulators ask for, the cabin path, and where AI helps and does not.
What EASA SC-VTOL and the FAA ask for in an eVTOL emergency landing, why composite airframes with battery packs differ from helicopters, and how validated explicit models and surrogates support the test programme.
Have a model that will not converge?
Send the geometry, the physics and the decision it has to support. We answer with an approach, not a sales call.
