AI Technical Summary

⚠Technical Problem

Existing eVTOL technology solutions suffer from problems such as energy density bottlenecks, insufficient transient response capabilities, and complex aerodynamic layouts in the selection of power systems, resulting in short range, limited payload, and difficulty in balancing safety and economy.

⚗Method used

The system employs a hybrid power system that combines hydrogen fuel cells and lithium batteries. Power distribution is dynamically adjusted through an energy management controller. Combined with the tilt angle changes of the tandem tiltwing, the hydrogen fuel cell system and the lithium battery system work together to meet the energy requirements of different flight phases.

🎯Benefits of technology

It achieves a long-range, high-safety, and economical aircraft design, increasing the range by 60%, extending lithium battery life, ensuring rapid power response and stability of the aircraft at critical moments, and reducing the total life cycle operating cost.

Abstract

The application discloses a longitudinal tilting wing vertical take-off and landing aircraft and a hybrid power control method thereof, and belongs to the technical field of advanced air traffic. The aircraft comprises: a longitudinal tilting wing configuration, a plurality of power units are distributed on the front wing and the rear wing and are tilted together with the units; a hybrid power system integrated in the fuselage, comprising a hydrogen fuel cell system matching cruise steady-state power and a lithium battery system matching take-off and landing transient peak power; and an energy management controller connected with the hybrid power system and the tilt angle sensor signal, configured to dynamically adjust the power output ratio of the hydrogen fuel cell and the lithium battery in response to the change of the wing tilt angle. The application realizes a breakthrough in flight range by deeply coordinating the power system with the longitudinal tilting wing configuration, guarantees millisecond power response and safety redundancy in the transition flight phase, and significantly prolongs the service life of the lithium battery through shallow charging and discharging management.
