EN This article presents tests results of monitoring technical condition of turbomachine blades. The method is based on a diagnostic model fi T12,T01 that utilizes the difference of phase shift of signals that are the result of blade operation y(t) and a signal x(t) of its environment described with appropriate distribution when the blade moves away from the sensor and when the blade tip approaches the sensor. The adopted diagnostic model indirectly takes into account present blade environment x(t) without the need to measure it [13,15]. The results of diagnosing three blades (worn out to a great extent, considerably worn out and worn out to a little extent) with the use of different distribution courses were presented. Shown results differ to a little extent from each other. However, they unequivocally specify the character of blade wear. Thus, the choice of distribution that represents non-measurable blade environment while determining parameters of a model fi T12,T01 for evaluation of technical condition of working turbomachine is optional and limited only by observation time.
