innovative multi - megawatt wind turbine are downright jumbo , stand more than 700 foot tall with 260 - foot blade spin 190 miles per hour at the hint . To ensure that these massive simple machine are up for 20 year of energy production , GE has created a tortuous test bed capable of sucking 20 yr of lifetime from a turbine in a affair of months .
GE latterly team with Clemson University to build the facility in South Carolina . It houses what GE draw as “ the world ’s most advance rig for try and formalise idle words turbine drivetrains ” . This auto attaches to a turbine ’s drivetrain — the snatch that connects the spinning propeller to the energy - producing engine — and repeat the forces imparted by wind , from a gentle breeze to a hurricane - force gale .
Able to lodge drivetrains up to 13 cadence in diam , the testing rig can also simulate the intense stress that spinning three 13 - gross ton turbine blades imposes on a drivetrain . It can even simulate a 15 MW power grid to see how these turbines come in varying grid circumstance , while a smaller lower-ranking rig can replicate a 7.5 MW scheme . More than 200 sensors mount within the turbine capture carrying out data for belated psychoanalysis .
“ Imagine putting a seven - long ton Mack truck on a lever tumbler arm that ’s more than a football game force field long , ” GE coach Mark Johnson state in a press statement . “ That ’s how much torsion we can deliver . ”
The $ 98 million testing readiness is expected to begin military operation after this summer in an movement to keep catastrophic failure — like this — confine to the research lab . [ Clemson University – General Electric1,2 ]
