Abstract: In response to the lack of clear and quantitative technology readiness assessment of physical tests required for the strength verification process of aircraft structures both domestically and internationally, research was conducted on the readiness assessment system of physical testing technology for aircraft structure strength. A framework for evaluating the readiness of physical testing technology for aircraft structural strength was constructed, the key/system technical connotations, readiness level classification methods/determination methods, level conditions/assessment method, and evaluation processes for aircraft structural strength physical testing were defined, and typical application cases were listed. The technical system and method proposed in this article are applicable to the quantitative evaluation of the readi-ness of key physical testing technologies and system technologies in the verification process of aircraft structural strength, providing methodological support for the structural strength profession to clearly grasp the relevant technical maturity levels and plan future development directions.

Key words: aircraft, structure strength, physical tests, technical readiness, assessment system
