Available in PDF, EPUB and Kindle. Book excerpt: Static stresses were obtained in laboratory experiments for a destroyer propeller, having aerofoil blade sections, and a super-cavitating propeller, having wedge-shaped blade sections, using specially constructed pressure chambers that allowed the blade faces to be loaded under air pressure. A new method for applying beam theory is presented that closely predicts the magnitude and distribution of radial stresses on the destroyer propeller blade. For the supercavitating propeller, neither the proposed beam-theory method nor a particular computerized-shell analysis can be considered entirely satisfactory for prediction of blade stresses.
