Precise Vacuum Simulation: The chamber is capable of simulating the vacuum environment experienced by spacecraft, with an adjustable vacuum range from 13.3 to 13.3×10⁻¹⁰ Pa (10⁻⁴ to 10⁻¹⁴ mmHg), sufficient to meet the thermal-physical simulation requirements for spacecraft.
Efficient Cooling System: Featuring a liquid nitrogen-cooled black radiation screen, the chamber can lower the simulation room temperature to below 100K, effectively simulating the thermal sink effect and replicating the operational state of spacecraft in extremely low-temperature environments.
Wide Vacuum Range: In addition to the standard vacuum of 13.3 Pa, the device can be adjusted to achieve even higher vacuum levels (13.3×10⁻¹ to 13.3×10⁻¹⁰ Pa), supporting studies on material sublimation, aging, and other characteristics, and fulfilling the requirements of more advanced research standards.
High-Precision Thermal Simulation: With a test chamber to spacecraft feature size ratio greater than 2:1, the thermal simulation error is less than 1%. This high-precision simulation can be corrected through theoretical calculations, ensuring the accuracy of the test data.
Compliance with International Standards: The thermal vacuum test chamber complies with the GJB 3758-99 standard, ensuring the equipment’s professionalism and reliability, making it suitable for high-precision testing of spacecraft and their components.
