Fox News on April 20, 2012, reported on a new fleet of model-airplane sized unmanned drones that can be launched from a slingshot on a moment’s notice are among the first wave in the massive rollout of commercial robot planes currently underway into U.S. skies. Excerpts below:

The Aggie Air Flying Circus are environmental crusaders instead, deployed to prevent water shortages and solve water resource challenges in Utah.

“[It’s an] on-demand fleet of UAVs that could be put in the sky at a moment’s notice,” explained Mac McKee, director of the Utah Water Research Lab at Utah State University that created the Flying Circus.

Water is a key resource in the state, where approximately 85 percent is diverted toward irrigating agriculture — meaning the rest of the economy relies on the remaining 15 percent. But satellite images weren’t providing adequate aerial imagery to let the lab effectively study wetlands and agriculture.

The drones have made the water delivery system far more efficient by better anticipating demand, freeing up a huge volume for Utah’s economy and citizens.

On February 3, the House of Representatives passed a bill that will lead to a dramatic increase in the number of drones permitted to fly in US airspace. As restrictions ease, UAVs have been the subject of considerable debate; the Wall Street Journal wrote on the 19th that more than 50 universities and law-enforcement agencies have been granted approval to operate them, according to Freedom of Information Act requests by the Electronic Frontier Foundation.

The Flying Circus fleet inexpensively gathers high-resolution images over wide expanses to paint a picture that experts can use to address a wide range of natural and water resources problems.

Each UAV can reach 1,000 feet, last about an hour, and cover a total of about three to four square miles, producing photos that are “geo-referenced,” or located on map coordinates.

Each of the half dozen aircraft in service has a name drawn from illustrious planes of the past such as “Raven,” “Spitfire” and “Mustang,” and each has its own unique color scheme painted so that the operator can confirm that the aircraft is right side up.

The UAVs are launched like a slingshot using a 100-foot bungee cord: The pilot ties the bungee to a stake in the ground, gets the proper tension and hooks the bungee to the aircraft before lofting it into the skies.

When the UAV detects it is at the right height and distance, the onboard computer arms the camera and the plane follows a pre-programmed flight path.
One computer flies it and another communicates with the camera. Together they identify both the location and orientation of the aircraft and coordinate this data with each image taken.

While other UAVs designed for the homeland cost as much as $150,000 per aircraft, the AggieAir fleet are under $10,000 apiece. And more are on the way.

This summer the team will deploy three new platforms including a UAV with a rotary design that will allow vertical takeoff and landing.

“Titan” will be larger, with an 11-foot wingspan and a 20 to 25 pound mass when fully loaded. The researchers expect it to have about 80 minutes of endurance. “Minion” a smaller aircraft, will address a fresh, yet undetermined target.
