The Development of a Robust Crack Growth Model for Rotorcraft Metallic Structures
Abstract
In the United Kingdom, helicopters have traditionally been designed using safe life principles. However, proposed changes to the airworthiness regulations require that, in the future, structures are qualified using flaw growth methods. Therefore, a robust crack growth model is required. The project consisted of six main areas of investigation namely the derivation of stress intensity factors, determination of typical flight load sequences measurement of fracture mechanics material properties for use iii models, measurement of crack growth data for model verification, evaluation and development of crack growth models, and definition of a helicopter damage tolerance methodology.
