The article presents a description of the hard-and-software tools of the system for measurement of the complex shaped blade tips' radial clearances and axial displacements. The blades of a complex shape are used in modern and promising gas turbine engines. System's hardware consists of high-temperature single-coil eddy-current sensors with additional thermocouples for sensitive elements' temperature error correction and front-end data processing module with ADC at the output of the measurement circuit and a microcontroller. The system's software consists of operation algorithms of a new generation, which ensure an adaptive data compression, code samples' approximation and information values searching, calculation of x, y-coordi-nates of the blade tips' displacements and other service algorithms. Experimental research of the prototype of the measurement system was realized. The main aim of the research was to evaluate the metrological characteristics of the system's prototype in a static mode and its operativeness in a dynamic mode. The quantitative estimations of the most significant indexes, the methodical and random error fractions, were provided. An object simulator was developed. It was intended for evaluation of the operativeness of the measurement system's hard-and-software tools. The principles of such evaluation are offered. These principles ensure several step-by-step operations, such as obtaining of the calibration characteristics in the dynamic mode during a simulator wheel rotation; setting of them in the system memory as the initial data for the further target coordinates' calculation; setting of the test values of x, y-coordinates and their comparison with the previously calculated values.
