About the inventions

The technical condition control of turbo engine working blades usually is carried out by using contact methods, e.g., with extensometers that are attached to the paddles, and ploughs ensuring the reception of the signal from rotating rotor. As nowadays turbo engines have several hundreds of working blades, it is almost impossible to control the technical condition of working blades this way. The recommended methods and devices allow obtaining the necessary information about the paddle condition in a contactless way by using contactless sensors that are placed on the turbo engine paddles and react to paddle rotation with short electrical impulses. The sequence of measurable impulses allows determining fully the variants of possible paddle oscillation forms. Device (picture 1) consists of impulse sensors 1 and 2 and equipment processing and ensuring automatic determination of oscillation forms.
