Large-size and low-cost double-deck structured airship pod made of composite material has and having no mechanical connection

Abstract

A large-size and low-cost double-deck structured airship pod made of composite material has and having no mechanical connection includes an exterior, a front cabin, a rear cabin and a passenger cabin.The front and rear cabins are the same and symmetrical, the upper part is a circular arc, the lower part is a three-dimensional ball, the passenger cabin is symmetrical, the upper part of the side isa straight line, the middle part is a large circular arc, the lower part is a small circular arc, and the bottom part is a large circular arc which is the same as the side large circular arc. The column frames, the floor frames and the outer panels, the frames, the beams, the floors and the hatch doors of the front cabin, the rear cabin and the passenger cabin are all foam sandwich composite structures, and the inner and outer panels, the frames and the beams of the normal hatch doors, the emergency hatch doors, the power hatch doors and the glass windows are all the same foam sandwich composite structures. The invention adopts the composite material structure design to carry out the design in a plurality of factors, and has the advantages of simple overall appearance, no mechanical connection of the whole composite material, light weight and low cost.

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
