Latest Patents

One of Grant's latest patents is an "Array system for supercavitating hydrofoils." This sonar system features a forward-looking array embedded in a cavitator, which generates a gaseous cavity to minimize hydrodynamic noise caused by turbulent pressure fluctuations. The design includes a marine vessel with a hull and a hydrofoil suspended beneath it, utilizing a cavitator to create a laminar flow over the hydrofoil and eliminate turbulent flow contact. The sonar array is strategically embedded within the cavitator to optimize performance.

Another significant patent is the "Method for computing three-dimensional unsteady flows by solution of the vorticity equation on a Lagrangian mesh." This method computes three-dimensional unsteady flows around an object by establishing an allowable error for vorticity term calculations. It involves providing object geometry, setting initial flow conditions, and iterating calculations to satisfy boundary conditions until a predetermined time variable is reached.
