AI Technical Summary

Technical Problem

Existing aircraft cannot simultaneously achieve the three core performance characteristics of water surface takeoff and landing, vertical hovering, and high-speed cruise. In particular, they have poor reliability in complex water environments, their power systems are easily damaged, and they cannot meet the diverse needs of water operations.

Method used

It employs a single engine located in a waterproof compartment above the middle of the fuselage, which drives the tilt rotor via a gearbox and drive shaft. Combined with an intelligent flight control system, it achieves smooth switching between different flight modes and optimizes the air intake and exhaust systems to adapt to the surface environment.

Benefits of technology

It improves flight efficiency, enhances safety and reliability, shortens takeoff and landing distances on water, increases range and payload capacity, and ensures stable operation in complex environments.
