Unsteady Force Measurements on Fully WeHed Hydrofoils in Heaving Motion
نویسندگان
چکیده
An experimental investigation is reported of the unsteady forces d ue to heaving motion of fully wetted hydrofoils of unity aspect ratio and also in two-dimensiona l flow. The tests covered a broad range of reduced frequency and determined the effects of variation in submergence depth, angle of attack, oscillation amplitude, and flow velocity. In genera l, the findings agree well with available theoretical calculations, but some unexpected variations were found for the case of a wedge-shaped foil and for changes in angle of attack.

Optimal hovering kinematics with respect to various flapping-wing shapes
Flapping-wing kinematics for insect flight has been studied for decades, especially since engineers became interested in flapping-wing micro air vehicles (FWMAVs). Previous work mainly focused on understanding kinematic patterns employed by different insects from the perspective of their trajectories and aerodynamics, and on optimization of kinematic parameters to enhance the understanding. How...
متن کاملThe aerodynamic benefit of wing-wing interaction depends on stroke trajectory in flapping insect wings.
Flying insects may enhance their flight force production by contralateral wing interaction during dorsal stroke reversal ('clap-and-fling'). In this study, we explored the forces and moments due to clap-and-fling at various wing tip trajectories, employing a dynamically scaled electromechanical flapping device. The 17 tested bio-inspired kinematic patterns were identical in stroke amplitude, st...

Unsteady dynamic behavior of TTCP model with different wrap around fin sets were investigated in a trisonic wind tunne. The aerodynamic coefficient force measurement in this wind tunnel shows good agreement in comparison with that of the NASA Langley Research Center in static case. The model was sinusoidally oscillated at three different frequencies of 1, 3 and 8 Hz at M=2.0 and the effects of ...

The present paper contains the test results of a planing catamaran model. The aim of the tests was to study the effect of hydrofoil in these types of crafts. First, experiments were carried out on the bare body (i.e. without hydrofoils) to obtain non-dimensional hydrodynamic resistance coefficient versus speed. Then, the model with hydrofoils, by various locations and attack angles were subject...
