Blade tip timing (BTT) measurement systems enable the measurement of blade vibrations by means of contactless sensors mounted in the engine casing. Despite this sophisticated and expensive instrumentation is commercially available since years, there is no simple and standard laboratory procedure to calibrate a tip timing system. Performance of BTT(More)
The aim of this work was to develop and validate an experimental methodology suitable for analysing on-site the behaviour of fibre-reinforced wooden structures. The proposed measurement method is based on the application of fibre Bragg grating (FBG) strain sensors. An analysis of adhesive behaviour was performed preliminarily, which provided indications for(More)
The article presents a hybrid monitoring technique for the measurement of the deformation field. The goal is to obtain information about crack propagation in existing structures, for the purpose of monitoring their state of health. The measurement technique is based on the capture and analysis of a digital image set. Special markers were used on the surface(More)
In this paper, an application of piezoelectric polyvinylidene fluoride (PVDF) films is presented, for the evaluation of the dynamic normal pressure exchanged between the ground and the tire of a moving car. A low-cost 2 2 prototype matrix made of PVDF films has been dynamically characterized and its measurement uncertainty was evidenced. The sensorized(More)
