Full-scale aircraft strength test technology of next generation fighter

This paper introduced the full-scale aircraft ground strength test and its requirements and analyzed the new problems and challenges in the test. Through the top-level planning for the test, new design mode and advanced loading technology are adopted to develop the overall technical scheme from the aspects of test boundary conditions, integrated platform, power system, measurement and control, and damage detection and monitoring. A number of new technologies, such as full-hard single-side bidirectional loading technology, test comprehensive platform design technology, boundary condition simulation technology, and power system design technology, have been studied and applied, which have improved design efficiency, accelerated test implementation speed, and improved test safety and reliability. These new technologies of this project have been successfully applied in the full-scale aircraft static/fatigue tests. The results showed that the test systems are safe and reliable, indicating that the test requirements and expected objectives have been achieved. The technologies have made great progress in the full-scale aircraft ground strength test, and the results have provided a high reference value for subsequent tests.
