    During U.S. Navy acceptance tests of the new 60,000-ton aircraft carrier Kitty Hawk, dummies representing?

  • Description

    Testing calibration and power of acceleration of Kitty Hawk catapults... Part of series of testing steam catapults -- with dummy vehicles ranging up to 45 tons caputulated from deck of Kitty Hawk at n.y. shipyards in camden into delaware river...

    Launching speed ranges from 80-150 knots -- dummies carry from 500 to 1000 feet into the river, after check to see river clear of shipping.

    These part of Navy acceptance tests of the 60-thousand ton aircraft carrier -- to prepare the four steam catapults which launch the heaviest type jet bomber from the 1047 foot flite deck.

    Planes are to fire between 60 and 80 of the dummies, which resemble the army's amphibious duck and simulate the weight of an airplane...

    The steam catapult was developed by the british -- these are a US improved design of the british design -- with more than one-thousand pounds pressure.....

    The catapults are twin steam cyclinders which run the length of a 250 foot catapult track just below the flite deck. In each firing, carefully adjusted steam pressure admitted into the rear end of the catapult cylinders, driving the piston forward.

    Two pistons are interconnected.

    Film otherwise self explanatory -- first shot today, went 500 feet into river; 700 feet was length of second shot.

    Background: During U.S. Navy acceptance tests of the new 60,000-ton aircraft carrier Kitty Hawk, dummies representing planes were recently shot from the flight deck by the ship's steam catapults.

    The dummies weighed up to 45 tons, and the first two practice shots sent the dummies 500 and 700 respectively into the Delaware River, New York. Later, the catapults will be used for launching heavy jet bombers. Launching speeds of the catapults is from 80 to 150 knots.
