Boeing's Hummingbird UAV hums along

A disparate pair of aviation R&D projects at Boeing have hit milestones recently.

The A160T Hummingbird, a helicopter-style unmanned aerial vehicle, last week flew for 18.7 hours without refueling, an accomplishment that Boeing described Wednesday as an "unofficial world endurance record" for UAVs between 500 and 2,500 kilograms (about 1,100 to 5,500 pounds)--a record that's pending certification by a key aeronautical sanctioning body.

But the record books aside, the flight also helps to show the Hummingbird's mettle as a potential aircraft for military use. During the flight, the turbine-powered unmanned rotorcraft carried a 300-pound internal payload--which in eventual real-life operations might be supplies for ground troops or gear for in-flight surveillance--and flew as high as 15,000 feet. When it finished, it still had about 90 minutes worth of fuel in reserve.

In a test flight last September, the Hummingbird carried a heavier load for a shorter period of time (1,000 pounds and eight hours). The A160T variant first flew about a year ago, taking up where an earlier piston-powered version left off.

Another May milestone for the A160T Hummingbird, which is designed to fly autonomously, involved so-called hover-out-of-ground-effect flights at 15,000 and 20,000 feet. The ability to hover at the relatively high altitudes would make the UAV more effective for missions in mountainous areas and help keep it out of range of some ground-based air defense weapons, Boeing said.

Measuring 35 feet long with a 36-foot rotor diameter, the Hummingbird in service is expected to fly at 140 knots for more than 20 hours. Boeing Advanced Systems is building the UAV for DARPA and for the Army and Navy.

Also this week, Boeing said that on May 13, it fired a high-energy chemical laser--in ground tests--aboard a C-130H aircraft, a step toward in-flight tests later this year in which the laser will fire at ground targets from on high. The directed-energy weapon is designed to fire through a rotating belly turret in the aircraft, known as the Advanced Tactical Laser.

And in a me-too missive straight out of the Cold War, the Russian news agency Novosti reported a patriotic response to the ATL test from an unnamed Russian defense industry "expert." Boeing, it would seem, is late to the game.

"We tested a similar system back in 1972. Even then our 'laser cannon' was capable of hitting targets with high precision," the expert is quoted as saying. "We have moved far ahead since then, and the U.S. has to keep pace with our research and development."

It's a C130H aircraft, not a C-301H aircraft.

Arrrrgh. I knew that, of course. My fingers hit the keyboard out of order, and then I simply missed the typo in proofing the story. Thanks for the catch!

When should we deploy UAV for wild fire fighting here in California, instead of developing and sending these plane to kill.

Although the military has taken the lead in developing UAVs for wartime purposes, unmanned aircraft have already been put into service for preventing and fighting wildfires.

For instance, NASA has used a Predator B drone, rechristened Ikhana, in California and elsewhere:

And the smaller ScanEagle has been used to map wildfire fuels in Alaska:

We do deploy UAVs for fire fighting. Google "Ikhana NASA fire".

It would be nice to have thousands of these dropping supplies into Myanmar! We could give a lot of humanitarian aid with these unmanned tools.

Cool toy. It takes 14 months to train an Army soldier how to fly a UAV.
