To investigate the time-variant mechanic-electric-thermal coupling performance of electric aircraft due to applications of innovative configurations and propulsion, our research proposes a Multiphysics Performance Prediction Method. Therein, the fast-slow dynamics analysis, order-reduction based on quasi-equilibrium, and multi-zone lumped-parameter principle, are comprehensively applied, to develop an augmented flight dynamics model with lower complexity but still acceptable fidelity. As such, the accuracy of performance prediction for key propulsive components, including battery pack, motor, and propeller, has been drastically improved to such a stage with relative error lower than 2.5%. The proposed method has been applied to conceptual design and simulation of electric aircraft prototypes with configurations of blended-wing-body, lift+cruise, and tilt wing.
