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. The aim of presented work was to study two types of special fireproof extiles covered with titanium silicide coating (Fig.1). In the paper the assessment of the change in heat resistance properties and analysis structure of TiSi coated fireproof textile were carried out. The aim of the research was to study the influence of TiSi coating on the infrared radiation (thermal) resistance generated in specially designed testing stage. The radiation intensity was registered with the use of therm vision camera. The research results showed the influence of the applied coating on the heat resistance properties of the textiles. Presented research is a part of a project the aim of which is to develop a tech ology for manufacturing the textiles used to produce the protective clothing for emergency services and military, as well as other coated materials for a wide range of applications. The new material should be characterized with increased heat resistance coupled with protection against gas pressure impact caused e.g. by gas installation damage.
