Measurement of the vibration of EC120 Colibri instrument board
Original language description
This paper describes the measurements of the natural frequencies of the EC 120 Colibri instrument board. For this purposes a special instrumentation was installed on board of this helicopter. The accelerometer unit, which was used for subsequent acceleration measurements was positioned it three on board locations. Measurements were performed for thirteen flights configuration. Data were recorded by the data acquisition system DAS 12. The recorded data were processed using Fast Fourier Transformation (FFFT). The purpose of these measurements was the establishing of critical amplitude of displacements of instrument board depending up the flight configuration.
