An advanced model of a new twin-hulled design has reached recently at the United States Navy Undersea Research Centre in San Diego, California. Designers say the twin-hulls improve stability in the water, permit greater deck area and allow more comfortable space the crew.
Navy engineers checked the new remote control model in the Research Centre's test tank and open water. Simulating heavy areas, the new design was tested against a conventional design model. As this from the U.S. Department of Defense shows, the new design rides the waves with virtually no pitch, roll or yaw.
Capable of speeds over 60 miles per hour (80 KPH), a ship based on the new design will be powered by lightweight gas turbine engines. Vessels of the twin-hulled design could range from 100-15,000 tons.
SYNOPSIS: A new twin-hulled ship design has reached the advanced model testing stage at the U.S. Navy Undersea Research Centre in San Diego, California. Designers say that the twin-hulls improve stability in the water permit dock area, and allow more comfortable living space for the crew.
The crew would live above the water line in a rectangular superstructure. Because of the design, engineers can isolate the noises that attract enemy submarines, an important advantage in confusing enemy sonar detection system.
The advanced model was tested against a conventional design model in simulated heavy seas. With the two torpedo-shaped hulls, the new design rides the waves with virtually no piton, roll or yaw. The conventional model, with a solid massive hull, wallows in the "deep sea" troughs.
For further checking, Naval engineers tested the model in the open water, as shown in this official film. The ship will use lightweight gas turbine engines and be capable of speeds over fifty miles per hour. Engines and fuel would be in the two submerged hulls. From an engineering point of view, vessels of the twin-hull design could range from one-hundred to fifteen-thousand tons. A one-hundred and ninety ton test model is to be completed next year.
