Model Airplanes

Dye in the water, moving at 10 inches per second, charts how the airflow moves across the airplane’s surface, called the “wedded areas” by engineering types. Like smoke in a wind tunnel, turbulence in the dye show where the airflow is disrupted. Information from the tests can validate computer models, which can be used to design future tweaks in the design, which can then be created by a 3D printer and put back into the water tunnel.

The results suggest that the clamshell doors not only work but are less disruptive than current methods, encouraging enough for Boeing to release test footage. For Princen, it’s another step toward ultimate adoption of flying wings in future military aircraft. “We turned a problem into an advantage,” he says.

Boeing is hardly alone in pursuing blended wing aircraft. Lockheed Martin, for example, in 2016 proposed a wingless aircraft as a competitor for the U.S. Air Force Air Mobility Command’s next-generation tanker aircraft program. Lockheed tested a heavy metal half-span model of the aircraft designed to withstand transonic speeds at NASA Langley Research Center, Aviation Week reported a year ago. Still, there are no programs of record with the Department of Defense. But when the next cargo airplane or refueling tanker program is announced, blended wings will be on offer—if the big aerospace companies can prove they are airworthy.

The benefits of the blended wing design are traditionally tied to efficiency from weight loss. An

STAMFORD — When high school students sign up for an aerospace engineering course, they typically expect a math-heavy curriculum.

But in Vincent Urbanowski’s class at the Academy of Information Technology and

If you’re a plane fanatic and want to get your own “wings” check out some of the 6 easiest foam planes to build from scratch at home.

I love airplanes, but I probably wouldn’t make a great pilot because I don’t have the best vision and have to always wear contacts or glasses. There was also that one time I tried out a flying simulator and crashed twice. Basically if I’m ever in a cockpit, it would benefit you to exit the plane as soon as possible. If you’ve always dreamed of flying a plane, this list of the 5 easiest airplanes to learn to fly in might interest you. However, my lack of skills when it comes to piloting a plane, don’t prevent me from being extremely intrigued by airplanes. Just yesterday I was watching an interesting television documentary about everything that goes into the thousands of flights around the world each day. I think it’s just pretty incredible that a metal tube, weighing a few hundred tons, can for one, fly, but also fly for hours at a time. There are many people in the world like me who just love airplanes and some even take their love a step higher and collect and build model planes.

There are a ton of model airplanes available for you to buy and build in your spare time. They even offer remote control versions, which I think would be awesome to have, if you have

Sacramento County’s Board of Supervisors voted Tuesday to immediately add drones to the list of “flying model airplanes” prohibited from the county’s regional parks.

“People who aren’t skilled in flying their aircraft can injure others,” said Michael Doane, chief ranger for county’s regional parks. “We are making this clear also to avoid conflicts between wildlife and humans.”

The ordinance had already prohibited flying model airplanes except in designated areas or by permit from the regional parks director. Tuesday’s amendment clears up an ambiguity of whether a drone can be categorized as a model airplane, Doane said.

Thomas Bartlett, CEO of Image in Flight, a drone photography service based in Rancho Cordova, worries that the amendment will impact his business and the public interest in flying drones. Image in Flight is the largest drone service in Northern California, Bartlett said; it has worked with Toyota and Golden 1 Center in the past.

“I sort of understand why they want to prohibit it, but this seems a bit excessive,” Bartlett said. “Sometimes there are events held in parks, so we are asked to work there. That will be a problem.”

First-time violators will receive a $50 fine followed by a $100 fine for a second offense. Additional violations will cost $250 each.
