“Chinese New Year” invokes images of fireworks but here’s another take. We hear little or no recreational flying occurs in China, but that turns out to be wrong. According to an article in Wired magazine by by Michele Travierso, the Do-It-Yourself spirit exists even in that highly controlled country. *** A Chinese DIYer named Mao Yiqing has built a human-powered aircraft, which he calls Mozi (after the 5th century inventor of the kite), using his skills running Oxai, a company that builds RC planes. Mozi was built using many of the same techniques and materials — balsa wood, styrofoam and carbon fiber — as his model planes. *** Wired reports, “His workshop is covered with pictures of Eric Raymond, an American pilot who flew his solar glider across the United States and, in June, over the Alps.” Yiqing is preparing his plane, which weighs 84 pounds and has a wingspan of 81 feet, for a 4-mile flight across Dianshan Lake near Shanghai.

Terrafugia, an enterprising company made up of MIT grads, announced the successful maiden flight of the Transition® Roadable Aircraft Proof of Concept. Or, the flying car. Congrats to the company, I wish them success with the two-seater. *** The big idea here of course is one that’s been tried before without success: a road-worthy, street-legal vehicle that, after unfolding the wings, can be flown as a legal LSA from any local airport. *** Lest I forget to mention it, no, you can’t take off from the street in front of your house – unless you live in an airport community and your street is a legal runway. *** The flight followed six months of static, road and taxi testing, says Terrafugia. The car/plane is designed to cruise up to 450 mi. at more than 115 mph, ride at highway speeds with wings folded (which takes, they say, 30 sec.), and fits in a household garage.

Chris Regis of Paradise Acft. did me a favor in absentia by filing a quick report from the field about the Heart of Texas LSA Expo fly-in he and other manufacturers recently attended. *** “The folks organizing really took great care of all vendors;it was a small event since it’s their first year but all the top manufacturers were there:Paradise, CT, Jabiru, Sting, Rans, Lambada, Sport Star, etc… *** During the first day, the wind was very strong and no one did demos but Sunday everyone was busy. *** The location is very good, between Dallas and Houston and I am glad that Karl and the rest of the folks decided to do this event. Jim, Texas is a huge market so we will definitely be there next year.

In a Safety Recommendation released Apr. 14, the National Transportation Safety Board (NTSB) “has investigated a series of in-flight structural breakups of Zodiac CH-601XL airplanes designed by Zenair, Inc…in the United States in the last 3 years. The Safety Board is also aware of several in-flight structural breakups of CH-601XLs that have occurred abroad. It appears that aerodynamic flutter is the likely source of four of the U.S. accidents and of at least two foreign accidents. The Safety Board believes urgent action is needed by the Federal Aviation Administration (FAA) to prevent additional in-flight breakups. Two of the accident airplanes were classified as Special Light Sport Aircraft (S-LSA).” *** In six of the breakups, NTSB noted 10 people were killed. *** Aerodynamic flutter occurs when aerodynamic and structural forces interact and lead to unsafe structural vibration in the airplane. Left undamped, the vibrations can quickly lead to structural failure. *** NTSB’s urgent recommendation to the FAA is to prohibit further flight of the CH-601XL until it can determine the airplane is no longer susceptible to aerodynamic flutter.

The ex-MIT whiz kids who formed their own company (Terrafugia) have just finished the fourth and final round of flight and ground testing on the Proof of Concept Transition® (POC) at Plattsburgh International Airport in upstate New York. *** A total of 28 flights were made, designed to evaluate handling, climb, performance, take-off and landing. *** “The Proof of Concept validated three basic goals,” says a company release. “We could design/build a roadable aircraft, drive it and fly it.” *** The tests will lead to several engineering and design modifications which will be incorporated in the Beta Prototype, targeted for 2010. If all goes according to plan, the company intends to make its first customer delivery in 2011.

Two “Lookie what we can do!” stories – one accomplished, one getting under way this week. *** Avweb reports two chommies (Afrikaans for friends) expect to fly their modified D6 Sling light sport airplane around the world! These adventurous lads modified their South Africa-produced, metal LSA (not ASTM certified in the US) to carry up to 118 gallons in each wing for long legs. Long, as in more than 2,000 nautical miles over water. Holy Lucky Lindy, Batman! And people think I’m nuts flying a hang glider. *** Mike Blyth and James Pitman are the pilots. They hope to launch from Johannesburg this Thursday and make a stop at EAA AirVenture Oshkosh. I’ll try to snag a shot of them. Bon voyage, guys! *** To follow the adventure Click here. *** NEXT UP in the Let’s Rock LSA Dept. comes from my next-issue column, Light Sport Chronicles.

Sad news today that the father of hang gliding, Francis M. Rogallo, who I had the distinct pleasure to meet at Kitty Hawk a few years ago when I flew a competition on the dunes, has passed away at 97. *** That’s a nice old age for all to aspire to, but his passing will be marked by every “diver driver” who ever took foot-launched flight. *** “Rog” was universally beloved within the community, and stayed in touch with industry leaders and pilots who lauded him for his gentle good nature and indisputable place as the person who’s aerodynamic engineering creativity directly led to hang gliding, ultralights and todays light sport aircraft. *** Rog invented what came to be known as the Rogallo Wing as a National Advisory Committee for Aeronautics (NACA) project engineer in 1948. He got patents for the flexible v-shaped fabric/frame Parawing in 1951. *** NASA became highly interested in a capsule-deployable version in 1958 for bringing astronauts back home, but dropped the complexities of deploying the steerable design in favor of the round parachutes we know, which were deemed adequate for the mission.
