777-have ridden on these-typically flights from Wash DC Dulles to Denver or Chicago to catch a flight from Dencer or Chicago to Rapid City,S Dak.The 777 is a very nice plane-did talk to some pilots as I was getting off-had time that day.They preferred "driving" the 777 as opposed to the 747.They felt the 777 had better takeoff ability.And they mentioned that it could operate on one engine.didn't know who built the engines. And one of the 777 I flew on was brand new-had that "new" smell like a new car.So,GE must build the motors for these-or if you were an aircraft purchaser-could you choose another brand engine.Guess with buying planes you can have your choice of engine builder-kinda like with trucks and some tractors.Yes,with turbine engines of all sorts failures do happen-becuase of the high speeds and temps-power plants aren't immune,either-their turbines made be GE or Westinghouse.These are larger than jet engine turbines-run from steam flowing thru them-high pressure and low pressure sections-reheat-med pressure section in fossil fuel steam turbines(this is what makes them so efficient--why power companines want to stay with fossil fuels) Nuclear fuels-the steam system doesn't use reheat.so the efficiency will be slightly less.and these turbines spin generators that have rotors weighing 100-200 tons! and they are spun at 1800,3600 RPM.Both rotors and turbines have "spin sploded" in power plants-can happen when the generator suddenly experiences a "no load" situation-becuase of OL-and overspeeds before the steam throttle closes.When a gen rotor spin splodes-takes out the stator section,too.So both have to be repaired-rewound.
remember there was a large Westinghouse generator production plant in Pensecola Fla,closed a long time ago.Don't know where its operations were transferred to.Now for central power plants-many companies specialize in rebuilding the turbines and generators-GE and Westinghouse made the majority of them.
