- Abstract: Electric Take-Off and Landing (eVTOL) aircraft is considered as the major
aircraft type in the emerging urban air mobility. Accurate power consumption
estimation is crucial to eVTOL, supporting advanced power management strategies
and improving the efficiency and safety performance of flight operations. In
this study, a framework for power consumption modeling of eVTOL aircraft was
established. We employed an ensemble learning method, namely stacking, to
develop a data-driven model using flight records of three different types of
quadrotors. Random forest and extreme gradient boosting, showing advantages in
prediction, were chosen as base-models, and a linear regression model was used
as the meta-model. The established stacking model can accurately estimate the
power of a quadrotor. Error analysis shows that about 80% prediction errors
fall within one standard deviation interval and less than 0.5% error in the
prediction for an entire flight can be expected with a confidence of more than
80%. Our model outperforms the existing models in two aspects: firstly, our
model has a better prediction performance, and secondly, our model is more
data-efficient, requiring a much smaller dataset. Our model provides a powerful
tool for operators of eVTOL aircraft in mission management and contributes to
promoting safe and energy-efficient urban air traffic.
