Wearing technology to travel to the stars: SpaceX chooses PT TEKNIK equipment for space suits
This space suit adopts a black and white splicing design, which is full of technology. The black part is made of polyamide fiber, which is not only elastic but also adaptable to various body movements. The white part is made of reinforced glass fiber, which has excellent high temperature and acid and alkali resistance, and can protect the safety of astronauts in extreme environments.The space suit has the functions of supplying oxygen and regulating body temperature. An interface on the thigh can be connected to the seat, connected to the life support system of the spacecraft, and delivers air and electricity. The helmet is customized through 3D printing technology to solve the problem of obstructed vision of fixed helmets in the past. It has an internal integrated valve sun visor retraction and locking mechanism, and is also equipped with a microphone. Each one is tailor-made for a specific astronaut.
Musk mentioned that the next step will be to develop an extravehicular space suit that can walk around on the moon and on Mars. Ideally, this space suit will have high mobility and not be particularly expensive, allowing people to walk around comfortably. The important thing is to develop it and eventually mass-produce it.
The design of the SpaceX space suit looks like something out of a science fiction movie, futuristic but also practical. It is designed to keep astronauts alive in the event of a cabin depressurization and a lack of air.
To ensure the comfort of the space suit, SpaceX ordered a heated manikin from Denmark’s PT Teknik for space suit testing. Let’s take a look at the technological power behind the space suit.
In space activities, space suits not only meet the corresponding special protection requirements, but also bring about complex heat transfer problems between the human body and the environment, which makes it particularly important to evaluate the thermal performance in the design and production of space suits. The warm manikin test system is an important means of studying the thermal dimension of clothing and the thermal sensation of the human body.
Space suits are special closed multifunctional clothing with artificial climate control systems, which can ensure the normal life activities and work ability of astronauts. In addition to protecting against various environmental factors in space, such as low pressure or vacuum hypoxia or oxygen deprivation, it should also maintain the thermal balance between the wearer and the external environment, so as to maintain the skin temperature and sweating rate at a level that does not cause discomfort, and keep the human body in a warm and comfortable state.
In space, you may encounter extreme weather, and the temperature difference may change from 160℃ to -180℃ in an instant. Whether the space suit can provide timely heating in extremely low temperatures is a huge risk for real-life experiments. The “warm mannequin” is responsible for this test. The warm mannequin has been used in foreign countries for a long time to test the insulation value of space suits.
PT Teknik, Denmark Thermal Manikin Test System
The PT Teknik heated manikin test system represented by Libao Technology has a lightweight fiberglass shell for the manikin’s body, which is durable and has strong aluminum joints for the neck, shoulders, elbows, hips and knees. Under various extreme test conditions, it can still ensure the structural precision and stability and durability of long-term tests.
PT TeknikSweating manikin
In addition, the mannequin has up to 250 sweat pores on its body, and can “sweat” like a real person. Put a piece of clothing on it, blow air on it, or set the temperature for it, and it will automatically record the heat exchange energy between the body and the environment, thereby judging the thermal comfort and thermal sensation of the clothes. A respiratory system can also be added to simulate the air flow caused by breathing.
