Wind power is a promising source of environmentally safe and renewable energy with a high potential. However, in order to fully exploit energy of wind power the construction elements of the wind turbine should be inspected periodically. Wind turbine blades are complicated objects for inspection because they have an arbitrary curved surface, are(More)
Wind turbine blades are complicated objects for inspection because they have a curved surface, are multi-layered, have variable thickness and are made from anisotropic materials. Ultrasonic contact pulse-echo immersion testing with moving water container has been selected for inspection of wind turbine blades, because this type of the inspection can be(More)
The inspection of a storage tank floor is a time consuming and expensive procedure, mainly due to necessity to empty and to clean the tank before an inspection. For this purpose a long range ultrasonic technique based on Lamb waves may be applied. Such an approach is used for inspection of pipes and can cover the distances up 100m. However the storage tanks(More)

Objective of this study was experimental verification of the acoustic computer model, which enables calculation of the signals reflected by triangles arbitrally oriented in space. Verification of the computer model was carried out comparing the C-scan images of triangle reflectors, obtained experimentally and by simulation in the case when ultrasonic beam(More)

The problems of the development of high-temperature radiation resistant ultrasonic sensors operating in a liquid lead-bismuth alloy are analysed. Experimental diffusion bonded bismuth titanate sensors for operation up to 450 °C were developed. For acoustical coupling with a liquid metal the sensor protector is polished or coated by a diamond like carbon(More)
For navigation of semi-autonomous robots various machine based vision systems are used. Ultrasonic systems are one of the cheapest, but some limitations reduce their performance. This paper is devoted to improvement of a data acquisition speed and noise robustness of such systems. These goals were achieved using simultaneous data acquisition along a few(More)
In new type nuclear reactors, the core is cooled by means of liquid metal. The use of heavy liquid metal for reactor devices under development possesses problems with the required inspection and maintenance due to the opaque nature of the medium. In contrast to water-cooled reactors there are no any other means except ultrasonic, which would enable to(More)
