Rovisco Pais, 1, 1049-001 Lisboa, Portugal Abstract During their operation, modern aircraft engine components are subjected to increasingly demanding operating conditions, especially the high pressure turbine (HPT) blades. Such conditions cause these parts to undergo different types of time-dependent degradation, one of which is creep. A model using the finite element method (FEM) was developed, in order to be able to predict the creep behaviour of HPT blades. Flight data records (FDR) for a specific aircraft, provided by a commercial aviation company, were used to obtain thermal and mechanical data for three different flight cycles. In order to create the 3D model needed for the FEM analysis, a HPT blade scrap was scanned, and its chemical composition and material properties were obtained. The data that was gathered was fed into the FEM model and different simulations were run, first with a simplified 3D rectangular block shape, in order to better establish the model, and then with the real 3D mesh obtained from the blade scrap. The overall expected behaviour in terms of displacement was observed, in particular at the trailing edge of the blade. Therefore such a model can be useful in the goal of predicting turbine blade life, given a set of FDR data. Plans of Control, Measurement and Monitoring with Risk Assessment Application to Rehabilitation works Rosário Oliveira * Adjunct Professor, School of Engineering Polytechnic of Porto,4200-485, Portugal The sector of the rehabilitation of buildings is developed in a growing context and of great demand in the rigor and ability in the management of production is a necessary condition for providing the best service and product to the customer, being an essential condition for maximizing profitability of construction activities. Defects and reworks should not be accepted as inevitable or even as certainties, but considered as a permanent challenge to the management of the work, being important to use risk assessment techniques in the planning and control of operations. The purpose of this article is to present a methodology for the elaboration of Control, Measurement and Monitoring Plans, within the framework of the production processes of a rehabilitation work, where it is necessary to ensure compliance with technical and regula ory requirements, based on the hinking on the associated risks. It is argued that this methodolo y has pplication and can contribu e in reducing the variability and uncertainty of defects and reworks associat d with th production of building rehabilitation works. © 2017 The Authors.
