Large-scale low-cost double-wall structure airship pod with composite materials without mechanical connection

Abstract

Composite airship pod with large size and low-cost double-wall structure without mechanical connection, including shape, front cabin, rear cabin, and passenger cabin; The passenger compartment is left-right symmetrical, the upper part of the side is a straight line, the middle part is a large arc, the lower part is a small arc, and the bottom is the same as the large arc on the side. The column frame of the front cabin, the rear cabin and the passenger compartment, the outer wall panels, frames, beams, floors and hatch doors of the middle frame are all foam sandwich composite material structures. The inner and outer panels, frames and beams of the hatch and glass windows adopt the same foam sandwich composite material structure. The present invention adopts composite material structure design and is designed based on various factors, the overall appearance is simple, no mechanical connection of all composite materials can be realized, and the weight is light and the cost is low.

Description

technical field [0001] The invention relates to the field of airship components, in particular to an airship pod with a large size and low-cost double-layer wall plate structure without mechanical connection of composite materials. Background technique [0002] Composites are a mixture. It has played a great role in many fields and replaced many traditional materials. Composite materials are divided into metal and metal composite materials, non-metal and metal composite materials, and non-metal and non-metal composite materials according to their composition. According to its structural characteristics, it is divided into: ① fiber reinforced composite materials. It is compounded by placing various fiber reinforcements in the matrix material. Such as fiber-reinforced plastics, fiber-reinforced metals, etc. ② Sandwich composite materials. It is composed of surface materials and core materials with different properties. Usually the surface material is high in strength and...

Problems solved by technology

[0003] The pod is one of the main parts of the airship. At present, the domestic airship pods are limited by materials. At present, the pods are mainly installed through mechanical connections, but this will increase the weight of the airship and affect the flight of the airship. The continuous development of composite material structure design can be considered to reduce the quality of the airship and reduce the cost of the airship. The important feature of composite material structure design is that the structural design and material design are carried out at the same time
