Sneak peek – awesome size of Super Aircraft Carrier – Gerald R. Ford

 

This is something you can’t usually see: the bow of an American nuclear aircraft supercarrier, the new Gerald R. Ford—the lead ship of a new class that will start replacing the Nimitz-class in 2015.

It was just put in place at Huntington Ingalls’s Newport News shipyard, at the mouth of the Chesapeake Bay, along the James River, Virginia.

Comprising six steel sections, the lower bow is more than 60 feet tall and is one of the heaviest superlifts to be placed on the ship. Construction of the lower bow superlift, the last major section of the ship below the waterline, began last year.

Gerald R. Ford represents the next-generation class of aircraft carriers. The first-in-class ship features a new nuclear power plant, a redesigned island, electromagnetic catapults, improved weapons movement, an enhanced flight deck capable of increased aircraft sortie rates, and growth margin for future technologies and reduced manning. The keel for Ford was laid in November 2009.  The ship is on track to meet its scheduled launch in 2013 and delivery to the U.S. Navy in 2015.

Soon cars will be ultra-light-weight and made out of carbon-fibre composites

The race is on to replace steel cars with carbon-fibre cars. All of the major automakers have inked deals to make the switch. The reason being that carbon-fibre is:

“10 times stronger than regular-grade steel and one-quarter of steel’s weight.”

“Using carbon fiber in lieu of conventional steel can lower the weight of a vehicle component by up to 50 percent, according to the U.S. Department of Energy. Cutting a car’s weight by 10 percent can improve fuel economy by as much as 8 percent.”

Weight is a big deal in cars. The heavier the car, the bigger the engine and, typically, the lower the fuel economy. This is especially true for electric cars who face limited mileage on one charge, reduce that weight by 10% and you can go an extra 50 miles.

Currently, carbon-fibre is expensive to make and only really used in racing cars. BMW, the first company to invest heavily in carbon, has already found ways to cut production costs.

“The carbon fiber fabric is placed in a mold, and resin is injected under high pressure and temperature. The process, which once took 20 minutes per part, now requires less than 10 minutes. Robots cut and handle the material and components, which previously were made by hand.

The robots will help BMW achieved big savings. A pound of carbon fiber now costs only a third as much as a pound used in the M3 CSL coupe’s roof when the limited-edition car was introduced in the 2004 model year.”

50K carbon fibers can be shaped and cured to produce spars for wind energy blades, golf shafts, compressed natural gas tanks, and pultruded beams.

 

Much of this production will happen in Germany or China, with both Volkswagon and BMW working with Germany’s SGL Carbon and General Motors signing with Teijin Ltd. But, just last month, Dow Chemicals signed a deal with Ford to begin research and production.

It’s exciting to think what this technology can do, not only for cars, but trucks, planes, boats, etc.

Energy researcher Amory Lovins, in this TED talk, thinks that when we fully start using carbon-fibre vehicles fuel economy in cars will shoot up to 200 miles/gallon. He says that halving the weight of the car creates compound effects: lighter car, requires a lighter engine, which makes the car even lighter.

At the Shuttle Landing Facility at NASA’s Kennedy Space Center in Florida, initial mating of space shuttle Discovery and the Shuttle Carrier Aircraft is complete in the mate-demate device. The device, known as the MDD, is a large gantry-like steel structure used to hoist a shuttle off the ground and position it onto the back of the aircraft, or SCA.

The SCA is a Boeing 747 jet, originally manufactured for commercial use, which was modified by NASA to transport the shuttles between destinations on Earth. This SCA, designated NASA 905, is assigned to the remaining ferry missions, delivering the shuttles to their permanent public display sites.

NASA 905 is scheduled to ferry Discovery to the Washington Dulles International Airport in Virginia on April 17, after which the shuttle will be placed on display in the Smithsonian’s National Air and Space Museum Steven F. Udvar-Hazy Center

Following delivery of Discovery, NASA 905 will ferry Enterprise from Udvar-Hazy to the Intrepid Museum in New York City. Endeavour is scheduled to be similarly moved to the California Science Center in Los Angeles later this year.
