Zhong Yang Ji Wei Guo Jia Jian Wei Wang Zhan·2025-05-19 00:29Core Viewpoint - The article highlights the significant advancements in China's aircraft strength research and verification over the past 60 years, emphasizing its critical role in ensuring the safety and performance of domestic aircraft like the C919 and AG600 [3][4][8]. Group 1: Development History - The strength research institute was established during the "Third Line Construction" period in 1964, marking a pivotal shift in China's aviation industry from repair to manufacturing and design [4][6]. - The first full-scale destruction test of the H-6 aircraft in 1968 demonstrated China's capability for large aircraft strength verification, marking a new phase in the country's aviation strength research [4][6]. - Over the past six decades, the institute has evolved from a single focus on strength testing to a multi-faceted approach that includes manuals, guidelines, standards, and tools [8]. Group 2: Testing Capabilities - The institute has developed a "building block" testing capability system that includes full-scale static, fatigue, and ground vibration tests, ensuring comprehensive validation of aircraft structures [6][7]. - It has completed hundreds of full-scale tests and thousands of large component tests, supporting the development of key aircraft such as the J-20, Y-20, C919, and AG600 [8]. Group 3: Climate Environment Laboratory - After 15 years of research, the institute established a climate environment laboratory that is internationally leading, capable of simulating extreme weather conditions for aircraft testing [9][10]. - This laboratory can recreate 12 types of extreme climate conditions, significantly enhancing the testing capabilities for aircraft adaptability [10][11]. Group 4: Software Development - The institute has developed the SABRE structural analysis software system, which supports various engineering and structural strength needs, breaking the reliance on foreign software [12]. - This software has been applied across multiple industries and has resolved numerous challenges in aircraft development [12]. Group 5: AG600 Aircraft Development - The AG600 amphibious aircraft, designed for both land and water operations, received its type certificate from the Civil Aviation Administration of China, marking a significant achievement in its development [16][19]. - The strength institute played a crucial role in verifying the structural integrity of the AG600, addressing unique challenges posed by its dual-environment functionality [19][20].
