- W86892025 abstract "Previous estimates of the efficiency of rowing have assumed (in the absence of any better data) that the water reaction force on the rowing blade, the `blade force', acts in a direction normal to the blade chord-line (oar shaft direction). In 1967 Wellicome suggested that there may be a component of the blade force parallel to the chord-line, pointing outwards, which would make the oar more efficient in the early part of the stroke [Rowing: A Scientific Approach, A Symposium, (Williams, Scott, eds.), Kaye and Ward Ltd, London, 1967]. The recent steady-flow 1/4-scale model tests of Caplan and Gardner [J. Sports Sciences, v25:643-650, 2007] detected a small such parallel force on the asymmetrical Macon and Big Blade shapes. It is possible that this component of force is actually zero within the experimental error, but if the direction of the blade force is tilted away from normal by the amount shown in the model tests, the efficiency of rowing propulsion may be one or two percent greater than previously estimated. However, those previous estimates of efficiency ignored the effect of oar bending which could reduce the efficiency of rowing by as much as 5%. There are reasons to suspect that the scale model results cannot be used to predict the magnitude or the direction of the force on a full-size oar during rowing: the flow is unsteady, and a crucial non-dimensional parameter, the Froude number, is significantly different in the two cases. It might be possible to detect a forward component of the blade force during rowing by measuring the tension strain such a force would produce in the oar-shaft outboard of the gate/pivot." @default.
