Cal State Long Beach Professor Receives $50,000 for Ship Hull Design Research to be Used in Future U.S. Navy ShipsHamid Hefazi, professor and chair of the Mechanical and Aerospace Engineering Department at Cal State Long Beach, has received a $50,000 award from M Ship Co. of San Diego to prepare a Phase I study of the company’s M-hull for use in future U.S. Navy ships.
Hefazi and a team of faculty and students from CSULB will develop Computational Fluid Dynamics (CFD) software tools to simulate and evaluate the performance of the patented hull design, described as a combination of a mono-hull, multi-hull and surface effect ship.
Originally designed for Venice, Italy’s canal transportation needs, the M-hull design significantly reduces a boat’s wave action, which impacts structural erosion of Venice’s buildings and also could affect vessel speed and stability of other potential naval or commercial applications.
“To reduce friction, you have to lift the boat out of the water,” Hefazi explained. “Hulls with surface effect characteristics, such as the M-hull, have tunnels underneath. As the ship goes faster and faster, the tunnels lift the boat, and the boat begins to move on a cushion of air.” Hefazi also noted that the research project was aimed at testing the hull design via computer simulation for high speeds up to 45 knots in deep water (30-plus feet) as well as stability and maneuverability.
“The M-hull offers higher speed, drag reduction, fuel efficiency, wake and signature reduction, shock mitigation and roll moderation, all vital characteristics of an efficient naval vessel,” said Charles Robinson, president of M Ship Co., a maritime design firm and parent company to Mangia Onda Company. “M Ship Co. will use Phase 1 of the SBIR (Small Business Innovative Research award) to study the M-hull for use by the U.S. Navy and prepare for a rigorous tow tank and prototype test in future phases.”
Hefazi commented that the research study gives his team the opportunity to mix academic work with potential industry applications. “Through research such as this and similar projects conducted under the Center for Commercial Deployment of Transportation Technology (CCDoTT), CSULB is becoming a well-recognized center for fast ship technology.”
