The Effects of Pitching Rate on the Hydrodynamic Properties of Hydrofoils,

Abstract

Little or no test data is available to verify theory predicting lift, drag and pitching moment of a hydrofoil in the presence of pitching motion commonly encountered in hydrofoil craft. The present paper presents the results of a wind tunnel investigation of the effects of pitching motion on two hydrofoil configurations. The results are compared to prediction techniques given in the U.S.A.F. DATCOM (Ref. 1). Finally, a verified force and moment prediction technique is presented. (Author)
