Structural strength test of a large transporter component
Project name: Structural strength test of a large transporter component
Brief introduction：In the development of large transport aircraft, structural integrity is of utmost importance and cannot be compromised. Aircraft components are required to endure a wide range of complex and extreme loads throughout their entire service life—whether during takeoff, sustained flight, landing, or while being subjected to various environmental stresses such as temperature fluctuations, wind, and turbulence. Any failure in the aircraft’s structural performance can result in severe and potentially catastrophic consequences. Therefore, to effectively mitigate these risks and confidently validate design assumptions, it is essential to conduct comprehensive static and strength tests that thoroughly assess the durability and reliability of every critical component.
In 2012, AVIC Shanxi Aircraft Industry Group (Shanfei) undertook a large-scale structural test project involving a major component of a large transport aircraft—the radome, the protective nose cone that houses radar and avionics. As part of this testing effort, Shanfei acquired 1280 channels of Dynatronic’s SE-86H Static Strain Test and Analysis System. This high-channel-count system enabled large-scale, simultaneous strain and displacement measurements across the entire component structure.
The SE-86H system was used to perform detailed static load and structural strength tests, replicating real-world forces that the radome would encounter during actual flight conditions. With its high sampling precision, stable performance, and multi-channel data synchronization, the SE-86H system allowed engineers to:
Measure strain distribution across various sections of the radome
Monitor the deformation of the structure under increasing static loads
Detect stress concentration zones
Validate simulation models used during the design phase
Ensure compliance with aerospace safety standards
The data collected provided a scientific and quantitative foundation for assessing the strength, stiffness, and durability of the component. It also played a key role in guiding the R&D of future transport aircraft and component designs, offering insight into material performance and structural enhancements.
This test not only confirmed the radome’s structural integrity and durability but also strongly supported Shanfei’s broader ongoing efforts in advancing aircraft innovation. Additionally, it contributed to improving the overall safety, reliability, and longevity of China’s rapidly expanding aviation fleet.
