Engineering students at the University of Maryland built a human-powered helicopter that flew successfully prior to graduation— just as they had hoped. Two other competing teams have achieved liftoff for a few seconds, but since none of them have claimed a world record, the University of Maryland has filed with the National Aeronautic Association for one. The gangly craft, named Gamera after a giant flying turtle in Japanese monster movies, lifted several inches off the ground for several seconds.
It succeeded on an earlier attempt, but on the first flight a judge’s camera was out of focus, so pilot Judy Wexler, 24, a 107-pound biology major and cyclist who volunteered for the attempt, had to again furiously flail at footpedals and a hand crank. She then successfully hovered the 100-pound craft.
Still, the chief prize remains. More than 30 years ago, the American Helicopter Society International set a goal of a human-powered helicopter that could hover at 10 feet for one minute. In 1980, Sikorsky Aircraft offered $20,000 for the achievement; increasing it to $250,000 two years ago after the University of Maryland announced it would pursue the prize.
It was fitting that the project was named for a turtle. The school mascot is a Terrapin, and the school battle cry is “Fear the turtle.”
Wexler, who had to pedal at 120 rpm to get the 43-foot rotors to turn at 18 rpm, was the first woman pilot to make the attempt, something that will stay in the record books even if a male pilot wins the Sikorsky award. A university representative said Wexler is looking forward to her career as a biology researcher and has not expressed a desire to become a pilot.
The craft was made of balsa, wood, foam, Mylar, and carbon fiber. The project has captured the commencement spotlight for the engineering team, and possibly and more important, a few job offers.
AOPA Pilot Senior Editor Alton Marsh has been a pilot since 1970 and has an airline transport pilot certificate and instrument and multiengine flight instructor certificates, aerobatic training, and a commercial seaplane certificate.
As the cold weather chills AOPA’s Headquarters in Frederick, many of us are inside generating new resources for flying clubs.
In my house, every Friday night is “Movie Night.” While the movies are rarely educational (I don’t think I learned anything from the Lego Movie), we look forward to the weekly opportunity to spend time together. Why not use the same concept for your Flying Club (with the addition of education, of course)?
AOPA Flying Club Manager Kelby Ferwerda posted the following on the AOPA Flying Club Facebook Page: “Recently I’ve talked with quite a few Flying Clubs about maintaining social activity through the cold winter months. Some clubs host Holliday Parties, others have Potluck Movie Nights. What does your club do to keep members involved during the chilly months?”
