Structural Development of Flight Systems

Abstract

An overview of the typical process and timeline for the development of structural systems is presented. Structural design and verification requirements, along with the approaches used to implement these requirements, are discussed. Special considerations are given to limit loads estimation, structural qualification by analysis, modal survey and test/analysis correlation, and response limiting during vibration tests. Several controversal issues that cause inconsistencies and difficulties in the current structural development process are identified and an approach for resolving these issues is recommended.
