This work investigates vibrations in aircraft structures with distributed electric propulsion under propeller mass unbalance. A Rayleigh–Ritz wing model including bending, torsion, gyroscopic and aerodynamic effects is developed and validated. Simulations assess design and operating parameters, supporting safer, more reliable electric aircraft structures.
