Drone Swarms as You Know Them Are Just an Illusion—for Now

Liam CobbPhoto by: Liam Cobb Look at all the pretty drones. Hovering above sports stadiums from Houston to Pyeongchang, many hundreds of them have lately sparkled in artful murmuration. On a recentTime magazine cover, 958 drones pixelated the sky. The world record, 1,374 LED-bedazzled microbots, was set by Chinese company EHang UAV in May. So-called drone swarms—the phrase people have taken up with gusto—are having their biggest, buzziest year ever. It’s an evocative word,swarms, and innocuous enough when applied to one ofIntel’s drone light shows. But it’s tinged with alarm—if drones can dance at twilight, they can also attack. Sure enough, a gang outside Denver sent a small fleet to harass FBI agents on a raid earlier this year. In Syria, rebels reportedly sicced a squadron of quadrotors on a Russian base.

Denali prototypes coming together in Wichita

Cessna Denali ile ilgili görsel sonucu

Three flying prototypes of Textron Aviation’s Cessna Denali are coming together in a Wichita factory ahead of a scheduled first flight in the third quarter, the manufacturer says.
All major pieces of the single-engined, nine-seat turboprop, including the nose, fuselage, wings and tail cone, are being fabricated.
Meanwhile, Textron Aviation engineers are continuing to run ground test articles through a battery of static and fatigue tests, the company says. The initial flight test articles of some components are also being built and tested.
As Textron Aviation’s answer to the Pilatus PC-12 and Daher TBM900, the $4.8 million Denali is scheduled to enter service in 2020 featuring a GE Aviation Catalyst turboprop engine.
The Denali is making progress as Textron Aviation nears the end of a decade-long wave of development activity. Two years after introducing the Cessna Citation Latitude, the super-midsize Citation Longitude is nearing certification with the US Federal Aviation Administration, the company says. Development of the large cabin Citation Hemisphere remains suspended while Textron Aviation awaits the results of Safran Aircraft Engines' ongoing review of the Silvercrest engine.
