Estimation of Warranty Period for Fatigue-sensitive Aircraft Structure Components
One of the most important problems in the fatigue analysis and design of aircraft structures is the prediction of the fatigue crack growth in service. Available in-service inspection data for various types of aircraft indicate that the fatigue crack damage accumulation in service involves considerable statistical variability. In this paper, we consider the problem of estimating the minimum time...
متن کاملInspection Policies for Fatigue-sensitive Components in Aircraft Service
As aircraft structures begin to age (that is, as flight hours accumulate), existing subcritical cracks or new cracks can grow in some high-stress points of the structural components. The usual approach is to inspect the structures periodically at certain intervals. Thus, a catastrophic accident during flight can be avoided. The problem then arises of choosing a sequence of inspection times whic...
متن کاملPreventative Maintenance and Failure Analysis of Aircraft Components
More than 10 years ago, the three major causes of failures in the Israel Air Force were: maintenance (-16% of failures), manufacturing (~14%), and design (-12%). While fatigue (~34%) and overload (~23%) were the two major failure mechanisms, more than 10% of failures were related to corrosion mechanisms. These include stress corrosion cracking, corrosion fatigue, localized corrosion, hot corros...
متن کاملAn investigation on fatigue failure of turbine blades of aircraft engines by high cycles fatigue test
Thermal stress, wear and material damage produce effects of high-cycle fatigue failures in aircraft engines. The loading configuration on turbine blades of aircraft engines consists of an axial load. The axial load is the centrifugal force combined with the tensile and compressive loads, caused by the natural vibrations of the blades themselves. Low-cycle fatigue and high-cycle fatigue loading ...
متن کاملA Demonstration using Low-kt Fatigue Specimens of a Method for Predicting the Fatigue Behaviour of Corroded Aircraft Components
Corrosion is well known to reduce the structural integrity of aluminium alloy aircraft components. In addition, it can cause early fatigue failures in components in which fatigue is not considered to be a life limiting factor. This is because corrosion damage, such as corrosion pits, is up to 100 times the size of the inclusions intrinsic in most aerospace aluminium alloys. The trailing edge fl...
