Flow measurements within the passages of rotating model fans was measured using laser holographic flow visualization and laser transit anemometry. The complementary nature of the two techniques uses the ability of holography to provide a diagnostic identification in three dimensions of main features of the flow and the ability of laser anemometry to provide quantitative measurements of the flow velocity at selected spatial locations. It is shown how the optical techniques, when suitably designed and ruggedized for a hostile environment, provide quantitative information of the intrapassage flows for a sequence of tests on wide chord fan blades, which aided the validation of their design intent.
