Structural Integrity Control Technology Based on Structural Damage Monitoring

Abstract

Structural integrity is an important attribute of aircraft structure. Usually, the description of structural integrity is a qualitative form, which emphasizes on the keep up of structural integrity. But, the quantitative description of structural integrity is help for carry out more comprehensive work for keeping up structural integrity. In this study, the concept of structural integrity control and a quantitative measurement method that uses structural integrity degree to measure structure integrity are proposed. And the structural integrity degree is evaluated based on durability degree, availability degree, safety degree and livability degree. Then, an aircraft structural integrity control technology based on structural damage monitoring is introduced. The implementation method and characteristic advantages of aircraft structural integrity control technology based on structural damage monitoring are expounded. Finally, aiming at the characteristics of military aircraft, the concepts of structural battle integrity and recoverability are established, and its measurement and control methods are briefly described.
