The present study focuses on both the effects of an aspect ratio AR and a tip-speed ratio Ω^* upon the tumbling of a flat plate with a low depth-to-width ratio λ = 0.067 - 0.167. The authors carry out measurements using a torquemeter together with the synchronised measurements of a plate's attack angle a for the analyses with a phase-averaging technique, in addition to measurements using a hot-wire anemometer and flow visualisations. As a result, we confirm that there are two torque modes T-modes I and II, as well as two flow-velocity modes V-modes I and II.
