Description

Technical Field

[0001] The present invention relates to the technical field of underwater vehicles, and in particular to a bearing structure device for an underwater unmanned vehicle. Background Art

[0002] With the development of underwater unmanned vehicles, the requirements for vehicle endurance and mission types have become more diverse. Therefore, the vehicle needs to carry more energy, payload and various equipment. The large-scale development of underwater vehicles has gradually become a trend.

[0003] Underwater vehicles are mainly composed of pressure-resistant structures and non-pressure-resistant structures. The non-pressure-resistant structure is mainly used as the main load-bearing structure of the vehicle, carrying the relevant mission loads and equipment required by the vehicle. The non-pressure-resistant structure uses a frame structure as the main structure, and a skin structure is installed on the outer surface of the frame to ensure that the outer contour of the vehicle is a streamlined structure. In order to reduce its own weight, the skin generally uses composite materials such as glass fiber and carbon fiber. It has a small weight, but due to the low overall strength of the screw connection, it cannot enhance the overall strength of the vehicle.

[0004] The load-bearing device is the main source of negative buoyancy for the aircraft, so its own weight needs to be reduced as much as possible. At the same time, in addition to providing an installation interface for functional equipment, the load-bearing structure device also serves as the main skeleton of the aircraft. During the subsequent lifting, transportation and use of the aircraft, the stress conditions are relatively severe, and its strength, safety and reliability need to be ensured.

[0005] The large-scale aircraft has higher requirements for aircraft hoisting devices, and multi-point hoisting is adopted. The hoisting points are far apart, the hoisting device has a large span, and a larger hoisting device is required. However, the stress of the aircraft structure is positively correlated with the distance from the hoisting point. The closer the hoisting points are, the greater the structural stress is.

[0006] Therefore, it is necessary to provide an aircraft carrying device that can shorten the lifting distance and ensure the strength of the main structure of the aircraft with limited increase in its own weight. Summary of the invention

If there is no upper beam, the boundary between the metal skin and the composite skin is the upper surface of the side beam.
