Double-layer Space Capsule Model

The double-layer space capsule model is usually a model that simulates the structure and functions of a space capsule. Here are some common features and relevant introductions about it: ### Structural Features - **Double-layer Design**: It has an inner and an outer layer structure. This design can simulate the division of different functional areas of a real space capsule. For example, the outer layer may mainly serve as protection and support, similar to the shell of a space capsule, which can withstand various stresses and radiations in the space environment; the inner layer can be used to simulate the living and working space of astronauts, with various devices and facilities arranged inside. - **Capsule Layout**: Generally, it includes different functional areas such as the simulated cockpit, living cabin, and experimental cabin. The cockpit may be equipped with various instruments, control consoles, etc., to simulate the flight control of the spacecraft; the living cabin will have a sleeping area, sanitation facilities, a dining area, etc., to meet the basic living needs of astronauts in space; the experimental cabin can be equipped with some experimental devices to simulate the environment of space scientific experiments. ### Functional Demonstration - **Space Environment Simulation**: Some devices can be used to simulate the environmental conditions of space, such as microgravity, vacuum, and radiation. For example, a special suspension system or magnetic device can be used to simulate the microgravity state, making the objects or small experimental devices in the model present a floating effect similar to that in space; the air inside the capsule can be pumped out through vacuum equipment to create an environment close to a vacuum. - **System Demonstration**: It can display various systems of the space capsule, such as the life support system, power system, communication system, etc. The life support system model can show how to provide oxygen for astronauts, regulate temperature and humidity, and deal with waste; the power system model can demonstrate how solar panels collect energy and supply power to the equipment inside the capsule; the communication system model can simulate the information transmission with the Earth's ground control center. ### Educational and Popular Science Value - **Popularization of Aerospace Knowledge**: It is a very intuitive educational tool that can help students and the public better understand aerospace knowledge. By observing and operating the model, people can have a deeper understanding of the structure and functions of the space capsule, as well as the living and working conditions of astronauts in space, stimulating their interest in and love for the aerospace industry. - **Scientific Experiment Teaching**: In schools or popular science venues, it can be used to carry out aerospace-related scientific experiment teaching activities. For example, physical experiments under microgravity and experiments on the impact of the space environment on organisms can be carried out using the model, allowing students to experience the process of scientific inquiry firsthand and cultivating their scientific thinking and practical abilities. ### Production Materials and Techniques - **Material Selection**: Some high-strength and lightweight materials, such as aluminum alloy and carbon fiber, are usually used to simulate the structural characteristics of a real space capsule. The shell may be made of plastic or composite materials with certain compressive and radiation-resistant capabilities, and various different materials will be used for the internal facilities and devices to restore their functions and appearances as realistically as possible. - **Production Techniques**: The production process requires a high level of precision and craftsmanship. 3D printing technology may be used to manufacture some complex components to ensure the accuracy of their shapes and dimensions; for some key systems and devices, such as simulated instruments and valves, fine machining and assembly techniques may be used to ensure their normal operation and display. The double-layer space capsule model is of great significance both in aerospace popular science education, scientific research, and as a model with collection value. It provides an intuitive and vivid window for people to understand space exploration.
