US government accuses Chinese hackers of stealing jet engine IP
The Justice Department has charged ten Chinese nationals -- two of which are intelligence officers -- of hacking into and stealing intellectual property from a pair of unnamed US and French companies between January 2015 to at least May of 2015. The hackers were after a type of turbofan (portmanteau of turbine and fan), a large commercial airline engine, to either circumvent its own development costs or avoid having to buy it. According to the complaint by the Department of Justice, a Chinese aerospace manufacturer was simultaneously working on making a comparable engine. The hack afflicted unnamed aerospace companies located in Arizona, Massachusetts and Oregon.
GE test-flies the world's largest jet engine
Airliners are growing ever bigger to haul more people per flight, which means they need appropriately massive engines -- and GE Aviation is happy to oblige. It recently conducted the first test flight of the GE9X, widely billed as the world's largest jet engine. It's easy to believe the claim from a glimpse (it's as wide as a Boeing 737), but the specs back it up as well: it has a whopping 11.2ft diameter front fan that, combined with carbon fiber blades, a next-gen high-pressure compressor and a new combustor, puts out over 100,000 pounds of thrust. For comparison, some of the earliest GE90 engines aboard Boeing 777s kicked out 'just' 74,000 pounds.
