Fig. 6 Stepped CSLDV run-up spectrogram (left) and its zoom around the III and IV blade resonances Table 2 Blade 4th ODS (158 Hz at 0 RPS) obtained via CSLDV and TLDV at different RPS 5. Coast-down characterization The TLDV and TCSLDV have been finally applied during the rotor coast-down starting from a rotation of 25 RPS. The experimental implementation required an accurate synchronization between the RPM reading, the generation of the waveforms feeding the mirrors and the TCSLDV output acquisition. 530
