Tiangong-1 Hydrostatic Seal Test Using Dynatronic DAQ
Project name: "Tiangong I" hydrostatic test
Brief introduction: Tiangong-1 was China’s first space laboratory module, specifically designed and developed as a significant and key milestone in the country’s ambitious space program. This pioneering spacecraft played a crucial and critical role in testing and validating advanced orbital rendezvous, docking technologies, and essential space station operations.
After successfully supporting the Shenzhou series of manned spacecraft, Tiangong-1 evolved into a versatile platform for multiple crewed and uncrewed missions, playing a crucial role in advancing China’s progress toward the development and construction of a permanent space station.
As part of the rigorous pre-flight testing phase, Dynatronic’s advanced data acquisition and testing systems were deployed to conduct a hydrostatic seal test of Tiangong-1. The goal was to verify the structural integrity and watertightness of the space module — ensuring that it could maintain perfect environmental seals under simulated space conditions.
In a hydrostatic test, the spacecraft is subjected to carefully controlled pressurized fluid environments, allowing engineers to thoroughly detect potential leaks, weak points, or structural deformities in both the module’s exterior surfaces and its internal compartments. This process ensures the integrity and safety of the spacecraft before it proceeds to further stages of development or launch.
Dynatronic’s role in this mission included:
✅ Providing high-precision measurement systems to monitor pressure stability and deformation during the test
✅ Recording real-time data across multiple test points to validate seal integrity
✅ Ensuring accurate performance verification under simulated external forces
The success of this hydrostatic test was a critical quality milestone for Tiangong-1, confirming that the module met the stringent safety and operational standards required for long-duration space missions.
Dynatronic is honored to have contributed to this landmark project in China’s aerospace journey. Our advanced testing technologies continue to support the nation’s ambitions in space exploration, engineering excellence, and scientific discovery.
