Array System for Supercavitating Hydrofoils

Abstract

This patent application discloses a sonar system that includes a forward-looking array that is embedded in a cavitator for generating a gaseous cavity that minimizes hydrodynamic noise resulting from turbulent pressure fluctuations. A marine vessel incorporating the sonar system includes a hull, a hydrofoil suspended beneath the hull by a strut, and a cavitator for generating a laminar flow over the hydrofoil and for creating a cavity for eliminating turbulent flow contact. The cavitator is located at a leading edge area of the hydrofoil. The sonar array is embedded into the cavitator. (4 figures)
