Description

Technical Field

[0001] The present invention relates to the technical field of aircraft storage and transportation, and in particular to an automatic temperature-controlled composite material storage device for aircraft. Background Art

[0002] With the update of design concepts and the increasing functional requirements, the design of aircraft storage devices is developing in the direction of light weight, simplicity, multi-function and universality. The storage devices commonly used in early aircraft were mainly wooden boxes and metal boxes. The disadvantages of wooden boxes are that they are heavy, large in size and poor in corrosion resistance. Especially when stored in the wild, they are easy to deform and break, and cannot provide a good storage environment for aircraft, shortening the shelf life of aircraft. Metal boxes are strong and durable, but their biggest disadvantages are that they are heavy, inconvenient to carry, have low payload, are not conducive to mobile transportation, and have poor corrosion resistance. Composite materials are light in weight, high in specific strength, good in fatigue resistance, corrosion resistance, and good in designability. With the increasing packaging requirements of advanced equipment such as aircraft, composite material storage devices have effectively solved the problems of anti-corrosion, anti-moisture sealing, etc., with excellent airtightness, high payload, and more and more applications. At present, there are few related studies in the field of aircraft automatic temperature control composite material storage devices. Some aircraft are sensitive to storage temperature, and storage devices are required to provide a stable temperature environment while being able to adapt to the harsh external ambient temperature changes. This requires the storage device to have a good temperature control function.

[0003] A related technical solution is disclosed in a patent "A fully automated spacecraft storage and transportation packaging box" 2023116033108. Several locks are evenly distributed along the circumference of the outer periphery of the box bottom, so that it can be detachably connected to the outer periphery of the box cover through the locks, and the upper end of the box bottom can be sealed and connected to the lower end of the box cover. The upper end of the box bottom and the box cover can form a closed satellite storage space. The satellite bracket is installed at the bottom of the box, and the satellite bracket is located in the satellite storage space. The automatic inflation and exhaust components and automatic temperature control components are respectively installed on the box cover or the bottom of the box. The automatic inflation and exhaust components are used to adjust the air pressure in the satellite storage space, and the automatic temperature control components are used to adjust the temperature in the satellite storage space. The signals of the automatic inflation and exhaust components and the automatic temperature control components are connected to the controller. However, it does not have airtightness, and the material is heavy, and the temperature control method causes its temperature control performance to be insensitive. Summary of the invention
