PREDICTIVE ASSESSMENT OF AN AIRCRAFT STRUCTURE BEHAVIOUR FOR PASSENGER AND CREW SECURITY
Journal Title: INCAS BULLETIN - Year 2009, Vol 1, Issue 2
Abstract
In the aerospace industry one of the most important requirements in the aircraft design and operation is the high level of fiability under various atmosphere and environmental conditions. The design and validation of such a system is a great challenge. It must meet several requirements such as: high resistence, low weight and a small occupied volume. The stresses that occur during the aircraft operation are extremely complex, being the result of the interaction of different systems.Consequently, in order to obtain an optimal design of the whole system, the design, testing and operating processes require a combination of laborious analysis and experimental data. As up to 90% of the structure failures are du to the fatigue, high performance methods of fatigue analysis are needed to estimate the aircraft ressources. These methods must enable a precise determination of the static and dynamic strains inder to correctly estimate the aircraft ressource. The project proposes an approach of some aspects of the aircraft/ aircraft subassemblies simulation and testing and develop o calculation methodology of experimental data and high performance numeric methods integration in order to establish the ressource.
