    Turbine parts that eat baby seals.

    OK, some more gas turbine pr0n.

    This is less sensitive engine part, it is a turbine blade out of a GE 7EA gas turbine engine. The engine produces about 114,000 HP in full trim and can burn 4 different fuel. Usually, natural gas, but diesel, fuel oil or syngas can be used. (syngas is synthetic gas that is 40% hydrogen and 60% natural gas that is synthesized via the gasification process).

    Anyway, the blade is made out of some GE 'propietary' alloy that is redily found on the interwebs. If you look hard enough you can find it.

    This blade is the stage 1 blade, it weighs about 16 lbs, there are 92 of them in just the first stage.

    Each one of these blades produces 400 horsepower. Thats right, this blade makes as much power as an M3.

    The blade is exposed to 2200F gas and when the engine is rotating at 3600 RPM the blade feels the pull due to centrifugal forces of about the weight of a locomotive hanging off of it. All this while it has to produce tangential forces (to make useful torque) and axial forces. This blade does not have a thermal barrier coating (TBC) because the firing temps are LOW ENOUGH it can get by with internal blade cooling.

    Look at one of the pictures where you see the blade tip, there are cooling holes that run the length of the blade, they keep the blade from melting. About 10% of the compressor air is used just for the secondary flow cooling circuit.

    This is a GE 7EA.

    This is the first stage turbine blade sitting on my desk.

    Cooling holes are clearly visible here. By the way, this design is primitive 30 year old blade cooling technology. Today the more advanced engines make this stuff look like an ancient design.

    Fun facts about the engine.

    It consumes about 643 pounds of air PER SECOND.

    It takes about 48 hours to cool down after it is shut off.

    It takes about 45 minutes for it to stop spinning once it's shut off, then it has to be spun back up using a big electric motor so the engine won't rip itself apart due to thermal gradients caused by the case cooling faster then the rotating assembly.

    The engine can burn almost any liquid fuel.

    It produces about 166,000 ft-lbs of torque at 3600 RPM.

    That's the turbine blade. In your turbocharger if you look at the turbine wheel you'll see a bunch of small vanes. This thing is ONE of those vanes in a three stage gas turbine that makes 114,000 HP.

    what's special about it? Is it made out of nickel? That one turbine would replace all 16 generators that we have here at work, if only it can start within 10 seconds of a power outage.

    Powering cities. whenever people say we should move for natural gas power, they mean we need more gas turbines. These things produce electricity for cities or factories.

    The blade is not very special, it is an old design. I just like it because it puts things into perspective on how powerful these engines are. This one blade makes as much power as ferrari, some of the bigger engines make about 1000 HP per blade.

    These engines typically take 2 hours to start, and they go through a complicated start up routine, it's not as simple as just pushing the on button and it's on. They have to be brought up to speed slowly until everything is up to temp, if not, engine = death.

    That blade is HUGE! holy crap, imagine getting hit by one of those things at 100k rpms. Strait shredder.

    Ahahaha i've seen that video before. The only thing that turns me off is the VW bug.

    Should have put that thing in a vette or something.

    Have you tried upping the boost yet?
