Big Buzz For $60,000 Electric Flight Prize
gilgsn writes "Electric Light Sport Aircraft are sprouting up all over. Now that the Experimental Aircraft Association is offering a 60,000 prize for the best ones, manufacturers are gearing up for the competition to be held the last week in July, at AirVenture 2011 in Oshkosh, 'The World's Greatest Aviation Celebration.' Airplanes will be tested for endurance, speed and time-to-climb. Pilots, charge up your batteries.." -
Orion Spacecraft On the Path To Future Flight
gilgsn writes "Preparations for Orion's first mission in 2013 are well under way as a Lockheed Martin-led crew begins lean assembly pathfinding operations for the spacecraft. The crew is conducting simulated manufacturing and assembly operations with a full-scale Orion mockup to verify the tools, processes and spacecraft integration procedures work as expected." -
Boeing, BAE Systems Show Off New Unmanned Planes
gilgsn writes The hydrogen-powered Phantom Eye unmanned airborne system, a demonstrator that will stay aloft at 65,000 feet for up to four days, was unveiled by Boeing today. 'Phantom Eye is powered by two 2.3-liter, four-cylinder engines that provide 150 horsepower each. It has a 150-foot wingspan, will cruise at approximately 150 knots and can carry up to a 450-pound payload.' Across the pond, BAE Systems showed off Taranis, a UAV that will test the possibility of developing the first ever autonomous, stealth Unmanned Combat Air Vehicle that would ultimately be capable of precisely striking targets at long range — even in another continent." -

Experimental Fuel-Cell Airplane Begins NASA Test
gilgsn writes "Planenews.com has a NASA press release from their Dryden Flight Research Center about the first large fuel-cell powered airplane to fly. The Helios prototype took-off Saturday at 8:43AM from the Hawaiian island of Kauai, using solar panels to power its 10 electric motors for takeoff and during daylight portions of its 20-hour shakedown flight. As sunlight diminishes, Helios switched to a fuel cell system to continue flight into the night. I wonder how long it will be before fuel cells are used on homebuilt experimentals." -

NASA Breakthrough For Solar Powered Aircraft
gilgsn writes "Planenews.com just received a news release from NASA's Dryden Flight Research Center about a breakthrough in fuel cell technology for solar powered aircrafts and how they used internet technology to broadcast data and HDTV video from the stratosphere above the Hawaiian island of Kauai. Their Helios Prototype could now fly through the night. I am sure that besides public communications, this will interest the military for their drones.." -

Web Enabled Spacecraft
gilgsn writes "Yahoo has an article from space.com about a satellite which will be operated by FTP over TCP/IP on the Internet! The CHIP (Cosmic Hot Interstellar Plasma Spectrometer) spacecraft will examine the stuff between stars, the so-called void of space that is actually rich with hot gas. The choice of protocol was dictated by economics. I wonder what OS it will run and if communications will be encrypted?" -
When Alcohol And Airplanes Make A Good Mix
gilgsn writes "Both for the economy and the environment, as suggested in this Iwon Money article. The Brazilians use sugar cane alcohol to fuel their modification of a single engine crop duster called the "Ipanema." The company projects a 25 percent increase in revenue from the new alcohol planes and increased income to convert existing gasoline-fueled Ipanemas to alcohol. With the threat of war for the U.S. and a subsequent raise in oil prices, this might be of some interest for our general aviation." -
Laptop Fuel Cells Approved For Air Carriage
gilgsn writes "According to reports in BusinessWeek, the US Department of Transportation has ruled that a new fuel cell developed by US company Polyfuel can be taken on airplanes. The announcement clears the way for the commercialisation of fuel cells as an alternative to batteries in notebook computers. The use of direct methanol fuel cells on aeroplanes has been questioned as they contain methanol, which is flammable. According to Jim Balcom, Polyfuel's CEO, the US DOT said that a fuel cell designed by his company could be taken into aircraft cabins when it goes on sale because it contains a relatively low concentration of methanol. Fuel cells are viewed as a promising power source in notebook comptuers as they are instantly refuellable (using fuel cartridges) and will power laptops two to three times longer than standard batteries. Full Story." This will be more exciting news when the fuel cells are actually available. -
Human Powered Paper Airplane
gilgsn writes: "The Raven is a honeycomb paper, foam and graphite-fibre tape, human powered airplane designed to beat the current record held by MIT's Daedalus . The plane is also powered by a 16MHz Motorola 68332. The technical specifications of the onboard computer are pretty interesting. Unfortunately, as reported on Ananova, the Raven recently crashed a mere 100 feet after taking off, causing some damage to its fragile structure. Maybe they could upgrade to a Pentium and convinced Lance Armstrong to give it a try..." -
Boeing to Develop a Fuel Cell Powered Airplane
gilgsn writes: "From Yahoo News: Boeing is working with a light airplane manufacturer in Spain on a fuel cell powered plane. The efficiency of electric motors, with their reliability, acceleration, lack of vibrations and noise has a lot to offer to general aviation. The project aims at exploring environmentally friendly modes of propulsion. I can easily imagine a hybrid aircraft using fuel cell technology for take-off and altitude gain, coupled with solar cells to sustain flight. I hope a kitplane manufacturer in the United States will read this. I can't wait to fly a fuel cell powered ultralight!" CD: The question is can a fuel cell deliver enough energy for a flight long enough to be practical.
