Probabilistic Analysis of Multi-Site Damage in Aircraft Fuselages
Most aircraft fleets nowadays are operating under the concept of damage tolerance, which requires an aircraft to have sufficient residual strength in the presence of damage in one of its principal structural elements (PSE) during the interval of service inspections. The residual strength however is significantly reduced due to multi site damage (MSD). In the present paper, a probabilistic frame...
متن کاملEffects of uncertainties on lifetime prediction of aircraft components
Today’s highly competitive environment in the commercial air transportation business instigates airline companies to continue operating their aircrafts beyond the design life, as long as the maintenance ascertaining their safe operation is more cost-effective than the investment into a new aircraft. In the context of damage tolerance of aging aircrafts, the residual strength of the fuselage ski...
متن کاملAdvances in Fatigue and Fracture Mechanics Analyses for Aircraft Structures
This paper reviews some of the advances that have been made in stress analyses of cracked aircraft components, in the understanding of the fatigue and fatigue-crack growth process, and in the prediction of residual strength of complex aircraft structures with widespread fatigue damage. Finite-element analyses of cracked structures are now used to determine accurate stress-intensity factors for ...
متن کاملStress Intensity Factors for Plates with Collinear and Non-Aligned Straight Cracks
Multi-site damage (MSD) has been a challenge to aircraft, civil and power plant structures. In real life components are subjected to cracking at many vulnerable locations such as the bolt holes. However, we do not consider for the presence of multiple cracks. Unlike components with a single crack, these components are difficult to predict. When two cracks approach one another, their stress fiel...
متن کاملModeling, simulation and analysis of a multi degree of freedom aircraft wing model
This paper presented methods to determine the aerodynamic forces that acton an aircraft wing during flight. These methods are initially proposed for asimplified two degree-of-freedoms airfoil model and then are extensivelyapplied for a multi-degree-of-freedom airfoil system. Different airspeedconditions are considered in establishing such methods. The accuracy of thepresented methods is verifie...
