THE HYDRODYNAMIC CHARACTERISTICS OF HIGH SPEED HYDROFOILS
Abstract
TOF HIGH SPEED HYDROFOILS, by Virgil E. Johnson, Jr. and Marshall P. Tulin. Jan 61, 34p. incl. illus. tables (Technical Report no. 001-6) (Contract Nobs-78396) Unclassified report Presented before the Institute of Aerospace Sciences 29th Annual Meeting, New York, N. Y. 23-25 Jan 61. DESCRIPTORS: *Hydrofoils, *Hydrodynamics, Cavitation, Fluid flow, Load distribution, Motion, Design. The methods used in the proper design of a hydrofoil boat or marine propeller are closely related to those used in the design of aircraft and aircraft propellers. Major factors in hydrofoil design, but which are absent in the aerodynamic case are: the influence of the near surface, cavitation, and ventilation. It is intended to acquaint the aeronautical engineer with these particular influences as they effect the design and operation of foils for marine use. The following specific subjects are discussed: the phenomena of cavitation and ventilation; design for subcavitating operation and its consequences; design for ventilated operation; supercavitating foils and their characteristics; the effects of a seaway with particular regard to motions.
