Model Airplanes

HASTINGS, Neb. (KSNB) – With skies clear for the first time in several days, the Kearney RC Club took off to show their model planes.

With the event moved to Hastings last minute, the club buzzed around the Skylark Field thanks to the Hastings RC Club welcoming them in.

The club wants more people interested to join them and show off their model planes. Some are gas and others have switched to battery power over the years.

“But people that are interested in aviation this is a very affordable way to enjoy it and spend some time with family and friends,” Kearney RC Club Vice President Rick Redden said.

Some of the people in the club are real life pilots.

“You kind of get the bug I guess,” Redden said. “When you’re young you like aviation. Things that fly are neat and it’s fun to experience that and i’m also a full scale pilot so getting in the plane is a different experience.”

There are some licenses required for flying and you can learn more here:

Tickets to the Airshow are non-refundable, but officials say if Friday or Saturday’s show is cancelled, those tickets will be able to be used at one of the remaining shows.

Matt Baker, Ivan Celanovic and Paul Roege, of Typhoon-HIL, break down how Controller Hardware in the Loop (C-HIL), and model-based engineering work to ensure your microgrid performs, and allows companies to test and validate microgrid design every step of the way.

Industry 4.0 is dawning, and digitalization, decarbonization, and decentralization (aka D3) are fueling the electric grid (r)evolution.  D3, in turn, creates opportunities for immense value creation, but invokes new technologies and design concepts, and change brings risk.

The emerging cyber-physical grid — with proliferating distributed energy resources (PV, wind, gensets, batteries, etc.); embedded controllers; intelligent sensors; communication links; large data; multilayered distributed digital control; and cloud software — is forcing industry leaders to embrace new design, test, deployment and lifecycle maintenance tools and processes.

Eaton’s Qiang Fu demonstrates Eaton microgrid controller in the loop with Typhoon HIL’s high-fidelity C-HIL microgrid testbed. See Eaton’s controller at Typhoon Booth #26 at the 2019 Microgrid Knowledge Conference.

Twentieth century power systems incorporated the physics of electromechanical systems – dominated by inductive generators, motors and transformers – which eventually grew into the synchronized grid that has been called the world’s largest machine.  Cyber-physical systems bring not only dramatic increases in data, but fundamentally different power devices.  The inverters, power converters and motor drives that are being installed in homes, infrastructure and factories today utilize rapid digital electronic power switching to manipulate currents, voltages,

The design of the 737 MAX has been under scrutiny since two crashes that killed 346 people. Attention has focused on the MCAS automated system that pushed the plane’s nose down, the sensors it relied upon to make those decisions and whether there were indicators to tell pilots something was wrong.

Former Boeing engineer Peter Lemme says the MAX’s wiring of two cutoff switches eliminated an escape route for pilots trying to get out of trouble.

Before, on previous models of the 737, the two switches worked separately. One could turn off automated systems and was labelled “Autopilot.” The other could cut out the motor running the stabilizer that controls the plane’s flying angle. It was labeled “Main Elect.”

On the MAX, the functions were combined and the two switches were physically made inseparable. It would be all or none. So when the MCAS automated system started to push the Ethiopian plane’s nose down, the pilots had to turn both switches off.

Without access to the electrical motor, the pilots tried to hand-crank the stabilizer into position but did not succeed.
