AI Technical Summary

Technical Problem

Traditional fixed-wing UAVs have easily damaged fuselage structures that require complete replacement, resulting in high maintenance costs, low repair efficiency, and difficulty in rapid deployment using general-purpose vehicles due to their fixed wingspan structure. Furthermore, their power configuration is not compatible with flight requirements.

Method used

It adopts a modular and lightweight design. The fuselage, main wing and tail are joined by mortise and tenon joints and glued splicing. The main wing is foldable and uses carbon fiber and aviation paulownia wood composite material. The skin is made of light wood board and heat shrink film composite material. The main wing airfoil is MH114, the tail is NACA0009, the engine is 2216-9KV1100, and the propeller is 9060 saber propeller.

Benefits of technology

It allows for individual replacement in case of partial damage, reducing maintenance costs and improving repair efficiency. The main wing can be quickly deployed via general-purpose vehicles after folding. The power configuration matches flight requirements, reducing energy consumption and improving range and wind resistance.
