Innovative Electric Aircraft Questions Traditional Design Rules Robert X. Cringely, a technology writer and airplane enthusiast, said, "Electric flight is full of new ideas as well as a lot of old ideas that need to be forgotten." He and his kids are designing an electric aircraft that challenges traditional aeronautical design concepts. Their boldest innovation is providing the aircraft with only enough power to get within gliding distance of their maximum target range. As their plane descends through the final glide path, the regenerative motor controller charges the batteries enough for 15 minutes of powered flight at the destination airport. It's a Bird, It's a Plane - Yes An MIT research team is developing a small UAV that can deal with wind gusts and fly quickly through an area with lots of trees or other obstacles. Their aircraft has articulated wings with no ailerons, and the entire wing is actuated to control the flight. This allows the plane to do knife-edge turns to avoid obstacles and get through narrow openings. The project's goal is to have an autonomous aircraft that goes 10 to 15 meters per second and can maneuver like a bird. Sleek Italian Design in Flyvolt Electric Aircraft Bruno Giardino created a concept design two-seat electric aircraft with optimized aerodynamics intended primarily for flying schools and air clubs. The carbon fiber aircraft has a T-tail with two electric motors. His goal is to minimize turbulence around the fuselage and wings. Wingspan on the 26-foot-long Flyvolt G 208 is 61 feet. Desert Locust Wings Are Tough, Lightweight The desert locust has tough but lightweight wings, so researchers are trying to figure out how to copy the wing material for small aircraft. This material is only one-tenth as the thickness of human hair, and it has to "withstand hundreds of thousands of wing beats without failure." One of the "design features" of the locust's wings is that cross veins act as barriers to cracks. The scientists hope to develop micro air vehicle wings with extremely light manmade material that has a veined design to provide strength and durability. Dragon's Draggin' Freight to ISS in October A historic moment in transitioning from science fiction to science fact is fast approaching. The space freighters written about by Asimov and Heinlein are becoming reality, with the SpaceX Dragon leading the way. In October 2012 the Dragon is scheduled to become the first commercial freighter to haul a full load of supplies up to the International Space Station.

HINTS FOR HOMEBUILDERS: HOMEBUILT FLUTING PLIERS Homebuilders love to make tools, especially if it will save them a few bucks. Brady Lane from the EAA staff shows how he made an inexpensive set of fluting pliers used in last week's featured hint. Watch the video.

TIMELESS VOICES OF AVIATION: LEO THORSNESS Leo Thorsness enlisted in the U.S. Air Force in 1951 at the age of 19. He graduated from flight training with Class 54-G in 1954 and became a fighter pilot flying the Republic F-84 and North American F-100. In 1966, Thorsness transitioned into the Republic F-105 Thunderchief and was sent to Takhli Royal Thai Air Force Base in Thailand to join the 357th Tactical Fighter Squadron as a Wild Weasel. Wild Weasels flew extremely dangerous missions tasked with locating and destroying North Vietnamese surface-to-air missile (SAM) sites. Thorsness was awarded the Medal of Honor for a mission flown on April 19, 1967, but before he even knew about the award, he was shot down 11 days later on April 30, 1967. He spent six years as a prisoner of war in Hanoi. Watch the video.

Where Are You Flying This Weekend? There are 102 other fly-ins and aviation events over the next two weekends listed in the EAA Events Calendar. Find one near you or add your event! Q&A:  Will use of a TSO C91 or a TSO C91A ELT meet the regulatory FAA requirements for a new installation in the Zenith CH 701 I am building? Answer: The TSO 91A unit can be used to satisfy the requirement for ELT installation for your CH 701. ELTs that comply with TSO C91 have not been manufactured since June 21, 1995, and the FAA mandated that all ELTs installed after that date comply with TSO C91A. All units installed using the TSO C91 requirements are not to be repaired, but replaced with TSO C91A-compliant units. On December 23, 1993, TSO 126 became effective, allowing for 406 MHz ELT units to be used. The use of 406 MHz ELT units is not mandatory for flights in the U.S. but is required in other countries.

EAA Desktop Calendar September 2012 Brittany Lueth, EAA 1086282, captured this photo of a 1936 Lockheed Model 12 Electra Junior at Thunder on the Lakeshore in Manitowoc, Wisconsin. Of the 126 Electra Juniors built, there are only approximately eight still flying. Brittany calls this photo Amelia's Vision as this airplane stood in for Earhart's Model 10E Electra in the 2009 film Amelia.

TECNAM LIGHTS UP SKY AT PARALYMPICS OPENING CEREMONY Millions of TV viewers around the world tuned in to the 2012 Paralympics Opening Ceremony in London to be treated to a spectacular Tecnam P2006T flying display. The Tecnam Twin was chosen by the Paralympics Games organizers to be the first act of the opening ceremony. It was specially adapted to enable it to put on the remarkable pyrotechnic show and was flown by Lance Cpl. Dave Rawlins (a British Army soldier recovering from injuries sustained in Afghanistan) and Tim Orchard, Tecnam's dealer for the UK, Ireland, and Iceland. Critical to the success of last night's flight demonstration was the exceptional support provided by the UK-based charity Aerobility. Since 1993, Aerobility has offered disabled people, without exception, the opportunity to fly airplanes. BRUCE'S CUSTOM COVERS DONATES RV-1 COVER Bruce's Custom Covers announced its support for Friends of the RV-1 with the donation of a custom-fitted, and remotely designed, covering system for the namesake aircraft. The cover serves to protect this historic aircraft at its new home in EAA AirVenture Museum's collection. Bruce's Custom Covers creates protective covers for airplanes, jets, helicopters, gliders, off-link jet engines, and more. BOGERT UPGRADES SOLUTION TO STUCK OIL FILTERS In response to customer needs, Bogert Aviation redesigned its 10M-OFT Oil Filter tool, doubling its torque value. Bogert tested this tool to withstand 60 foot-pounds of torque. Bogert Aviation's tool was designed to assist in removing a stuck filter without resorting to the traditional hammer, punch, chisel, or huge pump pliers methods. It is easy to use, will not slip, and prevents damage to nearby components. US AVIATION NOW A CESSNA UTHORIZED SERVICE FACILITY Cessna Aircraft has appointed US Aviation as an authorized customer service and support facility. This designation means US Aviation has met stringent knowledge and capability requirements and has invested in the proper tools and equipment necessary to perform Cessna authorized service, repairs, and warranty service. US Aviation, located at Denton Airport in Texas, offers maintenance service seven days a week, with 24 A&P and IA mechanics on staff and more than 28,000 square feet of climate-controlled service hangars. NAFI BOARD ADDS NEW MEMBERS Three new members have joined the NAFI board of directors. Tim Brady, professor and dean of the College of Aviation at Embry-Riddle Aeronautical University in Daytona Beach; Craig O'Mara, captain/check airman for United Air Lines; and Eric Radtke, president of Sporty's Academy, represent three significant additions to the NAFI board with their vast experience and current activity in the aviation industry. "As NAFI moves forward, we know it is important to have input from all areas of aviation where education and flight training are occurring," NAFI Board Chairman Ken Hoffman said. "Each of these individuals represents significant areas of the aviation training community, and as NAFI continues its work on behalf of the flight training community, we look forward to the contribution of these new members of the NAFI board of directors in its efforts."
