AI Technical Summary

⚠Technical Problem

Existing aircraft battery systems add unnecessary weight to the airframe and require additional structural components to ensure the rigidity and strength of the battery installation, thus complicating the aircraft airframe structure.

⚗Method used

The battery is housed in a sealed cavity formed by the connection of the frame, base plate module, and cover plate, integrating the body and the battery. The frame, cover plate, and base plate module serve as both the body support structure and the battery support structure. High-strength alloy materials are used, and heat dissipation and explosion-proof structures are incorporated to achieve the integration of the battery and the body.

🎯Benefits of technology

It reduces the overall weight of the aircraft, improves the rigidity and strength of the fuselage, solves the safety problem of battery thermal runaway, and enables rapid battery replacement and modular assembly, thereby improving operational efficiency.

Abstract

The present invention relates to the technical field of aircrafts, and provides an aircraft fuselage module, comprising a frame, bottom plate modules (1), cover plates (2) and batteries (3). The bottom plate modules (1) and the cover plates (2) are located on the inner side of the frame, and are connected to the frame to form cavities (4). The batteries (3) are arranged in the cavities (4), and are used for supplying power to an aircraft. The batteries (3) are integrated with a fuselage. The frame, the bottom plate modules, and the cover plates serve as both a load-bearing structure for the fuselage and a load-bearing structure for the batteries (3), are conducive to reducing the overall weight of the aircraft to realize light weight, and can provide higher fuselage rigidity and strength for the aircraft and the batteries (3), and help to solve the problem of thermal runaway of the aircraft. In the aircraft, several airframe modules (13) are connected to the fuselage module to form an aircraft body, thereby realizing modular assembly. At the end of the service life of the batteries (3) of the aircraft, the fuselage module can be rapidly replaced to realize the replacement of a new aircraft body and new batteries (3); alternatively, during operation, rapid replacement of the fuselage structure of the batteries (3) can be achieved to realize efficient operation, thereby providing an efficient design for later maintenance, after-sales service, and operation.
