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. To the media, both events were swarms. Take comfort, then, in this buzzkill: “The swarm is really an illusion,” says Mac Schwager, an assistant professor at Stanford who studies mul…

Sino-Russian widebody gets seven proposals for engine

CRAIC engine ile ilgili görsel sonucu

Developers of the Chinese-Russian widebody have received proposals from seven firms to supply the aircraft’s propulsion system.
The submissions were made to the China-Russia Commercial Aircraft Corporation (CRAIC) as according to the 30 May deadline. The bids came from both domestic and foreign suppliers, says Chinese airframer Comac.
CRAIC issued the request for proposal last December. Last week, Sukhoi Civil Aircraft, the commercial aviation unit for United Aircraft, told FlightGlobal that the developers of the aircraft have increased the engine thrust required for the jet. The requirement is now for 78,000lb-thrust turbofans, up from the previous 75,000lb-thrust specification.
“It has changed because of marketing demand that the aircraft be able to base in several high-altitude aerodromes in China. After the answer to RFP requests from potential engine suppliers is received, this measurement might also be elaborated,” it adds.
CRAIC says it will analyse, clarify and evaluate the proposals received by the end of the year. Rolls-Royce and General Electric are expected to be among the seven which have submitted bids.
United Aircraft and Comac are developing three variants of the twinjet. The baseline model will be the CR929-600 with a passenger capacity of 281 seats in a three-class configuration, and a range of 12,000km.
