Turbine Blade Crack Research

Description:

This test machine is specifically designed to simulate turbine blade crack and other machinery faults for research and educational purposes. The blade crack diagnosis/prognosis can be studied thoroughly using the wireless strain gauges mounted on the blades.

  • Key Features

    Key Features

    •    Variable pitch fan module with strain gauges attached to the blades.    

    •    Telemetry system.

    •    Weights to change the mass moment of inertia are installed on the rotors.

    •    An adjustable blade rub excitation device is attached to the baseplate at the circumference of the blades.

    •    The generator is used as a braking mechanism. The output from the generator is fed to a variable resistor (rheostat) where the load can be easily adjusted.

    •    Rotor dynamics and most of the mechanical (except belt and gearbox) or motor faults can be studied. Features modular, re-locatable component                       configurations, convenient instrument mounting, drive train alignment, and robust design.
