Abstract : The design of a three component rudder dynamometer intended for use with surface ship models approximately five feet long is described. This dynamometer is intended to measure the longitudinal force, transverse force, and moment about the centerline of the rudder stock. The design working ranges for these three quantities are plus or minus 0.675 pounds for the forces and plus or minus 0.1125 inch pounds for the moment. Satisfactory operation of the completed dynamometer is demonstrated by results obtained in a series of tests using a 1/96 scale model of a Mariner class cargo ship. Both self-propelled and unpropelled tests were run. Results obtained in these tests are compared with rudder performance calculated from airfoil data and results obtained by other experimenters.
