how big is the rudder on an aircraft carrier
Nimitz-class aircraft carrier All ships of the class are powered by two A4W nuclear reactors, housed in separate compartments. They power four propeller shafts and can produce a maximum speed of over 30 knots (56 km/h) and maximum power of 260,000 bhp (190 MW).[4] The reactors produce heat through nuclear fission which heats water. This is then passed through four turbines which are shared by the two reactors. The turbines power the four bronze propellers, each with a diameter of 25 feet (7.6 m) and a weight of 66,000 pounds (30 t). Behind these are the two rudders which are 29 feet (8.8 m) high and 22 feet (6.7 m) long, and each weigh 110,000 pounds (50 metric tons).[22]
Hughes H-4 Hercules The Hughes H-4 Hercules (also known as the Spruce Goose; registration NX37602) is a prototype strategic airlift flying boat designed and built by the Hughes Aircraft Company. Intended as a transatlantic flight transport for use during World War II, it was not completed in time to be used in the war. The aircraft made only one brief flight on November 2, 1947, and the project never advanced beyond the single example produced. Built from wood because of wartime restrictions on the use of aluminum and concerns about weight, it was nicknamed by critics the Spruce Goose, although it was made almost entirely of birch.[2][3] The Hercules is the largest flying boat ever built, and it has the largest wingspan of any aircraft that has ever flown.[4][N 1] The aircraft remains in good condition. After being displayed to the public for almost 11 years in Long Beach, California from 1980 to 1991, it is now displayed at the Evergreen Aviation & Space Museum in McMinnville, Oregon, United States.[5]
