LOW-ASPECT-RATIO WING THEORY AND ITS APPLICATION TO THE SHIP RUDDER,

Abstract

The 'Prago-Figiaivsky' wing theory of small aspect ratio was generalized, and the formulae for the coefficients of normal force, induced resistance and the center of pressure were established. A method was suggested to evaluate the lower limit of the critical angle of attack. After having recalculated the hydrodynamic forces of a rectangular plate, this method was applied to the ship after rudder and propeller. The results are in satisfactory agreement with the known experimental and calculated results. (Author)
