Title:
A PRELIMINARY HYDROFOIL DESIGN INCORPORATING A CAVITATION FREE OPERATION REQUIREMENT
Corporate Author:
BUREAU OF SHIPS WASHINGTON DC WASHINGTON
Report Date:

Abstract:
Over the past several years as the state of the art In hydrofoil design has progressed, the problem of cavitation avoidance has never been presented as part of the requirements to be satisfied in the preliminary design cycle. Cavitation becomes a problem when it develops In either of two forms 1 bubble cavitation which is associated with surface erosion and 2 sheet cavitation which is associated with a loss In lift.Prolonged bubble cavitation Introduces stress concentrations and structural loss. Unexpected sheet cavitation may develop into a disasterous dynamic response. The Bureau of Ships has a continuing program to develop a design procedure, incorporating the avoidance of cavitation, and make it available to the hydrofoil designer. The procedure, some of Its history and limitations is the basis of this technical memorandum.
