Secret Weapon: This Supersonic Blaster Rebuilds Jet Parts With Flying Powder

November 15, 2017
A few years ago, scientists working in GE labs in upstate New York came up with a cool idea for fixing broken parts. Literally. Calling the approach “cold spray,” they shot tiny metal grains from a supersonic nozzle at aircraft engine blades to add new material to them without changing their properties.

Above And Beyond: When Tragedy Strikes, These Pilots Spring To Action

On Jan. 18, a series of earthquakes sent 120 tons of snow careening into the Hotel Rigopiano at the foot of Gran Sasso mountain in central Italy and spurred Giuseppe Briganti into action. Briganti and his crew from the Italy State Police’s 11th Flight Department in Pescara spent hours airlifting victims to hospitals and bringing back supplies in a rescue helicopter. For the pilots the emergency was large-scale but not  unanticipated.

Better Watch Out! This Italian 3D Printing Workshop Is Taking A Leaf From Saint Nicholas

March 09, 2017

Every December, pilgrims from all over the world descend on the southern Italian seaport city of Bari to celebrate Saint Nicholas and visit the Basilica di San Nicola. The church is the final resting place of the famous saint known by millions of children for, among other things, his magical workshop staffed with elves who can make pretty much anything.

You won’t find the Italian commune of Cameri in many tourist guides. Located on the flat and fertile plains that stretch seemingly forever between Italy’s industrial dynamos of Milan and Turin, tiny Cameri seems a little lost. Like in most Italian towns, a splendid church and bell tower stand in the center, but during a recent visit in early February, its narrow streets were quiet and its stores either empty or closed. The busiest place in town was a pizzeria filled with a dozen locals finishing their lunch.

Atomic Bonding from a Bottle? These Scientists Use Supersonic Spray to Repair Turbines

August 11, 2015
Two years ago, scientists at the GE Global Research labs (GRC) in upstate New York found a futuristic way to fix things: blowing metal powder, at four times the speed of sound, onto parts in need of service. “The tiny bits of material fly so fast then they essentially fuse together when they hit the target,” says Gregorio Dimagli, materials scientist from Avio Aero. “Unlike welding, you don’t need to apply heat to make them stick. The bond happens on the atomic level. That’s why we are so excited.”
