Everything is Bigger in Texas, but These New Gas Turbines Up the Ante
GE – Harriet, whose real name is the 9HA, is the largest and most efficient gas turbine in the world.
GE spent more than $1 billion to develop the turbines. The company built a special testing center in Greenville, where engineers are currently putting the first Harriet through tests.
The turbine, which was manufactured at a GE plant in Belfort, France, is equipped with more than 3,000 sensors. They collect mechanical, temperature and exhaust data, and feed it to a brand new data-crunching center next door.
Under the hood, Harriet combines designs and materials originally developed by GE scientists for supersonic jet engines and other advanced technology. They include aerodynamic blades made from single-crystal alloys, thermal barrier coatings and ceramic matrix composites. Later generations of the turbine will also include 3D-printed parts. more> http://tinyurl.com/m2np8km
