A Swiss aircraft project will advance composites technology for the aircraft industry by a factor of two to three, says Andre Borschberg, CEO of a company called Solar Impulse, which will launch its first test flight next year of the manned solar-powered airplane. I caught up with Borschberg on the floor of one of the close to 20 buildings at the sprawling K 2007 in Düsseldorf, Germany. “Its unusual, for example, to use high-modulus carbon fibers,” said Borshberg. Get this: the wing span on the final model will be 80 meters, the same as the Airbus A380, which weighs 560 metric tons. The craft Borshberg will help pilot around the globe in about 12 four years will weigh just two tons. It will be powered by the latest in electric motor technology. The solar panels will only provide enough electricity to light up a very large Christmas tree, requiring enormous effort to keep weight low. The planes will fly at night on battery power. Solvay Advanced Polymers of Alpharetta, GA is a development partner for the plane and is already well along on a shielded throttle housing.
The amount of plastic clogging the ocean continues to grow. Some startling, not-so-good news has come out recently about the roles plastic is playing in the ocean, as well as more heartening news about efforts to collect and reuse it.
Optomec's third America Makes project for metal 3D printing teams the LENS process company with GE Aviation, Lockheed, and other big aerospace names to develop guidelines for repairing high-value flight-critical Air Force components.
A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
