A device for detecting and recording impacts along several axes of an aeronautic propeller blade having a root, the device comprising:
- an accelerometer integrated at a center of the root of the aeronautic propeller blade;
- and
- an electronic module to record, during a service life of the aeronautic propeller blade, any occurrence of the impacts at predetermined levels.
A device for detecting and recording impacts along several axes of an aeronautic propeller blade having a root, the device comprising:
- an accelerometer integrated at a center of the root of the aeronautic propeller blade;
- and
- an electronic module to record, during a service life of the aeronautic propeller blade, any occurrence of the impacts at predetermined levels, wherein said electronic module has a power supply, a circuit for the processing of accelerometer signals, an analog/digital converter, a microprocessor and a memory for storing the number of occurrences of the impacts.
A method of detecting and recording impacts along several axes of an aeronautic propeller blade comprising:
- obtaining data representative of the impacts via an accelerometer integrated with the aeronautic propeller blade;
- communicating said data from said accelerometer to an electronic module;
- comparing said data to predetermined levels;
- storing occurrences of the impacts beyond said predetermined levels in memory;
- and
- providing for reading of the number of said occurrences via a memory reading device.
