We present an integrated aero-propulsive model and trim method for a folding-wing VTOL UAV across hover, transition, and cruise. The approach captures non-axial inflow, rotor-wing interference, and geometry-dependent CG and inertia changes during wing folding, enabling trim analysis in both fixed-wing and multicopter modes.
