Mark Kelm’s desire to build faster, more efficient machines began when he played with a toy gun as a child. That early flirtation with a toy grew into a science project that tests how airplane surface texture affects speed.
The Chesapeake Science Point freshman presented his science project at an aerospace engineering conference earlier this month.
The opportunity propelled him closer to his goal of becoming a mechanical or aerospace engineer. As an engineer, he hopes to solve problems and make better machines, he said.
The goal of the project was to find the wing texture that would optimize air lift. The project consists of a computer fan that sits on the end of a foam tunnel, which is covered with two pieces of glass taped together. A small scale sits in the middle of the tunnel.
At his Glen Burnie home, Mark places a smooth model airplane wing, mounted on a stick, on the scale and turns on the fan.
The weight of the airplanes starts to fall as the wind picks it up.
He also has a wing covered in wrinkled aluminum foil, one covered with sand paper and one with bumps on the wing.
He said the wrinkled wing has the maximum air lift because the foil helps stabilize the wing from the changes in the wind direction, similar to how dents in golf balls help them fly farther.
In his past science fair projects, he has tested textures for submarines and rockets for optimal speed.
After Mark presented his project at the county schools science fair in March, he was invited by representatives from the American Institute of Aeronautics and Astronautics to speak at its November conference. His project also won the professional group’s award for outstanding middle school project at the March fair.
Mark said he was able to practice presenting complex science ideas to professionals, a valuable experience for his career goals.
His dad, an aerospace engineer, said speaking with unfamiliar audiences will help Mark practice pitching his ideas for funding, a key skill in the science world.
“He was extremely poised when presenting, much more poised than I was for the first 10 years of my career,” Bernie Kelm said.
Mark lives with his mom, Liz, brother Ben and dad.
Mark’s love for the mechanics of the physical world began when he realized he could reassemble his Nerf gun, which shoots foams darts, and make the darts go faster.
“I wouldn’t be satisfied with their performance; so I’d just take them apart, upgrade parts, remove unnecessary stuff,” Mark said.
“So he could shoot his brother harder,” Bernie Kelm joked.
Two years ago, Mark talked with some students at a University of Maryland open house event in College Park about how they used a wind tunnel to test car speed.
He realized they used the same mechanical technique he used to make his Nerf gun darts go faster — by increasing the air pressure.
His mom said she received a call from Mark that day announcing that he wanted to be a mechanical engineer.
“He’s the kid who likes to take things apart,” Liz Kelm said.
He hopes he eventually can test his wings on a bigger scale and take them out of the wind tunnel and into the open air.
And one day, he hopes to see wrinkled wings on planes.
“If I could get a more efficient lift, then that would save money. And then the U.S. can pay all of its debt, hopefully sooner, because they’re not spending as much money on military air craft gasoline” Mark said.
How does one arrive at a wedding? Car? Carriage? How about homemade airplane?
That’s the plan for aviation geek Asmelash Zeferu. After an aborted attempt earlier this year, he is taking to the skies in K-570, his handcrafted light aeroplane.
On November 28 the intrepid Ethiopian will fire his engine at an airstrip near Addis Ababa, and if all goes well, marry his fiance Seble Bekele the moment he lands.
Back with a bang
The Ethiopian’s second attempt comes five months after he first taxied to a runway 40 kilometers from the capital. That time a broken propeller — sculpted from laminated wood — scuppered his chances, but now he’s back and more confident than ever.
His engine has been upgraded to a model salvaged from a Volkswagen Transporter, doubling his power to 78 horsepower. Moreover, he’s sought professional advice to help him in the air.
Captain Solomon Gizaw of Abyssinia Flight Services and Captain Abera Lemi of the National Aviation College both confirmed to CNN that they had been helping out the budding pilot. Their mentorship sits alongside that of Rene Bubberman, chairman of the NVAV, the Dutch Experimental Aircraft Association — part of an international cohort backing Zeferu’s endeavor.
It’s been a long and remarkable journey, and for the Ethiopian a successful flight will be a moment over 10 years in the making.
Refusing to take no for an answer
Zeferu, 35, says that ever since childhood he’d wanted to become a pilot. He was on the right track, but when the time came, Zeferu was denied for the most arbitrary of reasons.
Leaving Alemaya University with a Bachelor’s degree in Public Health, he tried to enroll at the Dire Dawa branch of the Ethiopian Airlines Aviation Academy.
“I couldn’t fulfill the air school height requirements,” he explains. Zeferu was a centimeter too short.
Despite this setback, Zeferu was unperturbed.
“I decided to build my own aircraft if I couldn’t be a pilot,” he reasons, “then I’d be able to fly high in the sky.”
YouTube tutorials and flying Beetles
The first stage of his labor of love lasted 10 years. Aviation manuals and YouTube tutorials were his guiding stars; every aspect of aircraft manufacture gradually imbibed in painstaking detail.
When the time came, Zeferu opted to model his plane on one used by trainee pilots in the U.S. in the 1920s and 1930s.
Some items were salvaged, others bought second hand from the Merkato market in Addis Ababa. The 8.5 meter wing was crafted from timber imported from Australia, with each wooden panel hand-sculpted. But there was one element of the plane Zeferu could not imitate.
The design called for a Ford engine, but the amateur engineer “couldn’t get [it] cheap in Ethiopia,” settling instead for a four cylinder, 40 horsepower model stripped from a Volkswagen Beetle — since upgraded to a 78 behemoth at a cost of 12,000 Birr ($570).
But after a year and seven months Zeferu had finished. Not bad for someone who had “never stepped onto an airplane,” never mind worked within the aviation industry.
A second bite of cherry
Zeferu’s earlier disappointments are now behind him and he’s ready to complete the task at hand.
In doing so he would take a seat among a pioneering group of amateur enthusiasts from the continent. Not all have been successful: Kenyan Gabriel Nderitu has attempted to take off 13 times, but like his dream, his plane has so far failed to fly. Nigerian student Mubarak Muhammed Abdullahi created his own helicopter in 2007 with parts stripped from, amongst other things, a Boeing 747. Abdullahi had more luck, and after lifting 2.1 meters off the ground went on to gain a TED Global Fellowship and an aircraft maintenance scholarship in the UK.
Zeferu has made some modifications after receiving advice from fellow flight enthusiast Rene Bubberman, chairman of the NVAV, the Dutch Experimental Aircraft Association.
“We gave him some well-meant advice about his prop and especially about test flying,” says Bubberman. “[His project] deserves a lot of respect… [it] truly breathes the spirit of the early airplane pioneers and his enthusiasm is contagious.”
On November 28, Zeferu will return to the same air field and rev his newly-modified machine. Taking off at 90 mph, the dizzying height he will aim for is 10 meters — not unreasonable considering he has “no parachute or anything to protect me.”
Zeferu demurs about the achievement of getting off the ground — he has other concerns. “To fly an aircraft is not a big deal,” he explains. “The greatest danger will be in landing.”
That will involve slowing the plane down from its cruising speed of 70 mph to 45 mph, then hoping the wheelbase — taken from a Suzuki motorcycle — holds out.
Asked how he has been able to train for this, Zeferu says YouTube flight simulators have been key.
‘We have lift off…’
Touching the skies in his homemade airplane is only the first step for Zeferu. He hopes a flight school will accept him in the near future so he can train as a commercial pilot. However the long-term goal is to boldly go further still.
“My dream is to become an aerospace engineer at NASA,” he admits. “And I will be.”
Central Michigan University’s Finch Fieldhouse was buzzing from the many model airplanes and quad-copters flying around inside.
Mid-Michigan Radio Control Helicopter Association (MMRCHA) held their 5th annual Holiday Classic Benefiting the Toys for Tots Saturday.
The donated funds and toys go to the Marine Toys for Tots in Clare and Isabella County, according to club president Randy Gibson.
“We’re very fortunate to enjoy the modeling hobby and it breaks our hearts to think of a child waking up on Christmas Day with nothing under the tree,” Gibson said. “We like to do our part to help the kids in our community.”
Spectators watched pilots fly radio-controlled helicopters, airplanes and multi-rotors.
If someone wanted to try flying a model, they could “buddy box,” or co-pilot with a pilot.
The pilots attending the fundraiser were members of the Academic of Model Aeronautics, or AMA, coming from all over Michigan and London, Ontario.
“They’re a really generous group of people who have come the distance,” Gibson said.
Every member had to pay a pilot entry fee of $10 or bring a toy, he added; most people do both, because they believe it’s a worthy cause and more than happy to help.
Lucinda “Cindy” Clark, Isabella and Clare County coordinator, said last year they collected 7,400 toys which went to 2,400 children.
For every dollar donated to Toys for Tots, 97 cents go to buying toys.
It’s largely a volunteer-run cause, but Clark said her volunteers are rewarded in other ways during distribution days that make all their hard work worth it.
Once a woman who came to the distribution with her children tried to give Clark $5, which she reluctantly accepted as a donation.
The mother told her that those $5 was all she had for Christmas and she wanted to repay those granting her children with gifts in some small way; Clark said that the woman could always volunteer next year to repay the kindness.
“I like to help children get something for Christmas,” Clark said. “I appreciate what Gibson does. It goes to show how you can include people in something you’re doing to make a fundraiser.”
Gibson, who has piloted planes since he was 10, said it’s a relaxing hobby and it has led him to forming strong friendships over the years.
“I get to meet great people and all these people have become one family,” he said. “I (also) like being able to see the excitement in the kids’ eyes when they fly a model plane for the first time.”
Nine-year-old Megan Szymczak was in fact flying her quad-copter for the first time that day; she had gotten it for her birthday.
“It’s been fun watching my dad and brother fly their planes,” she said.
Being able to control something on her own was even more fun, though.
Her brother Matt, 14, was the expert according to their father Mark.
Matt said he has been flying everything from planes to quad-copters to helicopters to jets for the last four to five years.
“I like the thrill. There’s so much fun to do,” he said. “It’s exciting how one thing always leads to something else.”
What he meant was that he had gone from flying a night vapor, a small and light airplane for beginners, to controlling a Mcfoamy plane which was much larger and able to fly outside even in colder conditions.
He added that there were many ways to expand on this hobby, because the pilots in the area meet every three weeks to fly their models together.
Gibson added that there are competitions and airshows for those flying model airplanes, too.
As for the fundraiser, Matt said it’s a great way to do what you love and donate at the same time.
The distribution of the toys will take place in Finch Fieldhouse on Dec. 19, according to Gibson.
U.S. aviation regulators on Monday will propose mandatory inspections and, if necessary, replacement of suspect parts on nearly 1,600 jetliners to prevent potentially catastrophic failures.
The pair of proposed Federal Aviation Administration safety directives, related to certain Boeing Co. and Embraer SA jets and slated to be formally published Monday in the Federal Register, are unusual because they are each intended to counter a…
More than a century ago, the Wright Brothers achieved the first successful flight with an aircraft weighing 750 pounds, including the pilot and motor. That’s quite a different proposition from the A380 superjumbos of today which carry hundreds of passengers and weigh in at over 570 tonnes.
The pace of innovation in the aviation sector has hardly let up in the 112 years since the Wright Brothers’ landmark moment. The search for increased efficiency and greater income – the global airline industry’s revenues have doubled over the past decade, according to the International Air Transport Association – has also become critical for the UAE, which has emerged as one of the world’s leading airline hubs.
Researchers at the Masdar Institute in Abu Dhabi are working to help find those efficiencies by testing airplane parts currently being made in the UAE.
Yusra Abdulrahman, 25, a graduate student from Dubai, is part of the team working on the development of a non-destructive testing and thermal imaging system in collaboration with Strata, the Al Ain-based aerostructure manufacturer.
The Masdar Institute researchers are working on a model which tests carbon fibre and polymer parts supplied by Strata.
“We’re not trying to create something new, but rather innovate the existing [testing] techniques,” she says.
The Masdar Institute system takes two to three minutes to test structures, a significant difference from the current models on the market that take hours, according to Ms Abdulrahman. An additional improvement is the benefit of automation requiring less manpower.
Improvements to this type of system are only being studied in three countries: the United States, Japan and now the UAE. Ms Abdulrahman said that as a result, this will make the UAE more competitive in the industry. “And this will strengthen our companies’ global competitiveness,” she says. “High-end tech companies in Abu Dhabi are currently available across many sectors such as aerospace and can achieve a sustainable manufacturing growth.”
Mohammed Omar, the founding chair of the department of engineering systems and management at the institute, says that the complexity of airplane structures was becoming more intricate, requiring more advanced systems for testing parts.
Aircraft materials must be lightweight yet sturdy. “And that’s our goal: to ensure that everything that’s being fabricated is up to standards and is basically safe to use in the building of airplanes,” he says.
The professor adds that not only was it important to be cost-conscious, but it was imperative to have a knowledge transfer within communities. “It’s important that we’re not just building systems without the support behind it,” Mr Omar says. For Ms Abdulrahman, “innovation isn’t an option any more, it’s a necessity. The mind has to be innovative”.

“Reason is immortal, all else is mortal” said Pathagoras, but for a brief span of 59 years, Steve Hed trumped reason with pure creativity.
From the earliest days of the second Industrial Revolution, when a chain first drove a cog that turned a sprocket that moved a wheel, the motor age was dawning, but technology doesn’t just happen, it happens just, and the catalyst of change was the bicycle, the most noble of inventions. The innovations began to flow in the final years of 19th century. The pneumatic tire was developed for bicycles, and let’s not forget that motorcycles began life with pedals. The earliest cars and trucks ran with chains and sprockets; some were steered with handlebars. As late as WW II an American fighter plane used a hand cranked chain and sprocket drive to raise and lower the landing gear. The thing looked like it might have been cannibalized from a `40’s Schwinn tank cruiser, and it turns out the company actually made airplane parts in support of the war effort.
A Novel Concept, Made in America
The robust DNA of bicycles was the genesis of the mechanized transportation civilization we live today. It is an inescapable fact that the pioneers of the motorized movement, Ford, Champion, Chevrolet, and the Wright brothers to name a few, started their careers as bicycle racers and shop mechanics. The leapfrogging spiral of technology that first drove the bicycle, then the auto industry was fueled by the relentless fire of competition, and examples abound.
An appreciation for Steve Hed is enhanced with an understanding of this significant linage, researched and masterfully scribed by cycling historian Peter Nye in Fast Times of Albert Champion. Champion won Paris Roubaix in 1899 then migrated to America to race bicycles and motorcycles-at the same time- while perfecting the modern spark plug. Like Champion, Steve Hed’s contribution- not unlike that of Bill Gates- came from the refinement of a specific application of technology. Although the current pace of innovation may seem to have slowed in this century, a more apt description is that change is simply more refined. Chad Moore, Mavic’s director of marketing reminds us. “Calling Steve Hed an icon in cycling innovation would be an understatement, he consistently set benchmarks that drove all of us to build better products.” Michael Hall of Zipp confirmed, “Steve was such a rival it fueled the industry’s innovation for years and years. He was a pioneer in using measurement, data and technology to advance athletes, both in the pro peloton and in triathlon.”
Of course you probably know Steve Hed from his oh-so-sweet, deep dish wheels, built wider for a reason, and his aero bars that national and world champions use to get to the top of the podium. These innovations are responsible for making Steve Hed industry famous, but his Horatio Alger start up though humble, was right on target from the beginning. HED did not begin with cool wheels, rather Steve’s first creations were water skis and skateboards. The wheels were an evolution into the then mysterious and exotic material known as carbon fiber.
Steve started his business career as the owner of a bike shop, Grand Performance (still in operation) in St Paul, Minnesota. One of his customers was a young professional triathlete named Anne, whom he decided to sponsor with his first wheel. “Steve had a horrible diet, for breakfast he would drink a diet soda, and I could always tell how many other girls had been in his shop that morning by the number of diet sodas lined up on the counter.” Anne’s competitiveness went well beyond diet sodas, and eventually they were married. Another professional triathlete, Scott Molina, alas The Terminator, was Steve’s second sponsored athlete. Molina was on a winning streak, and soon he was Hed’s billboard. It was a time of burgeoning triathlon popularity, a sport of “buy your ride” newbies with unlimited discretionary plastic. You could rightly say the business opportunity was ripe for the picking.
When Italian pro cyclist Francisco Moser obliterated Eddie Merck’s formidable hour record on the mile high Olympic Velodrome in Mexico City, Steve took note of two items – the large closed disc wheel that helped Moser go faster, and the God-almighty price tag. Cycling was Steve’s first market, and the first big purchase-14 wheels- came from Huffy bicycles, the brand that won the bid for making bikes for the US national team.
How do you nurture creative genius?
In the case of Michelangelo or Mozart the answer to this question would involve patronage, a quality today that can be re-labeled as team work. When relaxed, team work becomes play. Steve and Anne Hed created a successful business model from the cornerstone of a purpose driven marriage. To all of us, they were an example of just how marvelously effective the institution can be. In an interview with Bike Radar, HED’s Paul Ellis remarked “The two have been in, for 30 years, the perfect communion of Steve’s out-of-the box creativity and Annie’s feet-on-the ground attachment to the realities of business.” With Steve free to explore his creative conscience, an “inveterate tinkerer” as Ellis put it, or “player” as I would describe him, the world we knew was ready to evolve.
Beginning with the College Station, TX wind tunnel (with its spooled up propeller from the Enola Gay B-29 that dropped the bomb on Hiroshima, Japan), some of the staid axioms of bicycle performance changed directions. His much wider patented toroidal rims blew away the long standing belief that wheels had to be feather light, have short rims, and be ribbon thin to be fast. Hed’s design concepts were first validated in the record books and later, with the press in attendance, at the Allied Aerospace wind tunnel in San Diego. The one piece carbon aero bar which saw production in the early 2000’s confirmed the same level of innovation.
“When I saw that long, out the window gaze, I kept quiet….”
Steve Hed was never satisfied with his creations, he was constantly searching of ways to improve, with more surprises yet to be released. Anne knew that he had ideas in his brain, in their infancy and she knew he would communicate the germ of those thoughts when he was good and ready. “Steve stressed a bit over bringing new stuff to market and then displaying it at the Las Vegas bike show, but he loved communicating with anyone from shop owners and buyers to consumers, and it seemed like every year he lost his voice on the first day of the show.” That was Steve – his door was always open, but he also enjoyed being a dad to his two kids, Andrew and Rebecca and didn’t really like traveling that much when it took him away from the family.
A Collector Of Memories
Steve’s memories were contained in the utilitarian gadgets of a by-gone era. The old bikes that he wanted to own as a kid but couldn’t afford; I can see him polishing his prize vintage collectables from every decade beginning in 30’s, mostly European brands, Spanish, English, Italian, acquired during his European travels. Perhaps reminding him that the clock was always ticking, he also enjoyed an array of old mechanical watches. According to Anne, his rural farm boy background was represented through a collection of smoking toy steam engines.
Steve soon owned his own wind tunnel, and the wheels never stopped tuning, but he was always searching for a creative environment to spark that eternal flame of cerebral combustion. The time he spent riding, often his historic bikes, over the multi-directional rural gravel roads around the HED Shoreview, Minnesota headquarters may have been the perfect link to the future. The open road was his precursor of ideas, paying homage from the saddle- as it should be- simultaneously prying open doors to the future by opening the past.
In the Gravel
His last foray of play came with the Almanzo 100 gravel ride in the Twin Cities area. The mere description of a free, 100 mile gravel race inspired Steve’s imagination, and he was immediately drawn to it. When the event was in danger of folding he stepped in to sponsor the ride. In 2014 2,000 people rode it with him in iconic Cino Heroica style, without the benefit of course markings or GPS.
So, when I called Anne, whom I have known for more than 25 years, she flat told me. “Sorry John, I only have 30 minutes.” Together, we recalled a lot while she chatted with me on a blue tooth from her car while waiting for her daughter to finish a physical therapy session. But in those 30 minutes, Anne dispensed a Steve Hed-lifetime of stories and recollections…
And when that span of 59 years ended, his creativity naturally yielded to reason; and yes, it’s sad that he left us so soon, but his footprint is deep and the world as we know it has improved because he was here. So let’s celebrate a life well lived, what more can I say, except: Miss ya bro!
Thank you for your message, we will be in touch very shortly.
Sorry, there has been a problem and your message was not sent.
