Abstract:

There is a lack of clear and quantitative technology for readiness assessment of physical tests required for the strength verification process of aircraft structures both domestically and internationally. This paper conducts research on the readiness assessment system of physical testing of aircraft structural strength. A framework for evaluating the readiness of physical testing technology for aircraft structural strength is constructed. The key/system technology connotations, readiness level classification methods/determination methods, level conditions/assessment method, and evaluation processes for physical testing of aircraft structural strength are defined, and typical application cases are given. The technical system and method proposed in this article are applicable to the quantitative evaluation of the readiness of key physical testing technologies and system technologies in the verification process of aircraft structural strength, providing methodological support for structural strength professionals to clearly grasp relevant technical readiness levels and plan future development directions.

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