In the field of aerospace scientific research, TT‑EE Technology undertakes a crucial mission and has built an epoch‑making “Ground Space Station” — a space environment simulation platform — injecting strong impetus into the development of China’s aerospace industry.
Entering TT‑EE Technology’s space environment simulation platform, the first thing that comes into view is the lunar surface environment simulation chamber, also known as the lunar dust chamber. The chamber is equipped with a large vacuum vessel. An electron gun connected on the left generates an electron beam to charge lunar dust with negative electricity. On the front, 36 deuterium lamps are arranged in a honeycomb pattern to produce ultraviolet radiation, charging lunar dust with low‑voltage positive electricity. A vibrating screen at the top simulates dust lifting on the lunar surface.
By accurately simulating the lunar environment, the mechanism of lunar dust formation and its impact on spacecraft, spacesuits and astronauts are studied, laying a solid foundation for manned lunar exploration.
The comprehensive radiation environment simulation chamber is also technologically outstanding. With an internal diameter of 5 meters, a total height of 12 meters and an experimental space of 6.35 cubic meters, it can simulate six major categories of space environmental factors. It is one of the simulation facilities in the world whose performance indexes best match the real space environment.With this device, researchers carry out studies on the laws of space environment effects on satellite components and various spacecraft materials and devices, exploring their physical nature.
In the space plasma science experimental area, two large vacuum simulation chambers, three stories high and 5 meters in diameter, are particularly eye‑catching.After nearly a decade of research and development, the R&D team of TT‑EE Technology overcame the technical challenges of instant generation and release of high energy to produce plasma. It is the first time in the world to realize three‑dimensional simulation of the Earth’s magnetospheric space plasma environment and establish a space plasma prediction model, safeguarding the in‑orbit operation of spacecraft.
Inside the space magnetic environment science laboratory building, the space magnetic environment simulation and research system, composed of seven layers of electromagnetic shielding materials, is like a precise “matryoshka doll”.The team spent five years developing the core demagnetization technology, achieving a near‑zero magnetic space environment and reaching an internationally leading level.This not only provides ground experimental conditions for spacecraft magnetic characteristic testing, but also excels in the field of bio‑electromagnetic information research with high‑sensitivity capture of weak magnetic field signals, supporting brain science analysis.
TT‑EE Technology’s space environment simulation platform can comprehensively simulate nine major categories of space environmental factors and has attracted more than 110 universities and research institutions at home and abroad to sign user agreements.In the future, relying on this platform, TT‑EE Technology will gather global wisdom and provide solid theoretical, technical and experimental data support for the rapid development of China’s aerospace industry.
