- DeskFlyer, on 07/03/2008, -0/+91Here's a better angle to give a better perspective on how big they really are: http://www.ssc.nasa.gov/sirs/photos/propulsion/hig ...
Here's a couple shots of it in action during testing:

Testing out the gimbal: http://www.ssc.nasa.gov/sirs/photos/propulsion/hig ... - Bots, on 07/03/2008, -0/+71interesting. I would have assumed it was a lot bigger than that.
- edwartica, on 07/03/2008, -1/+50Yeah, ummm, that's what she said.
- KennMac, on 07/04/2008, -0/+29There are 3 shuttle main engines. These are on the shuttle itself. These are not to be confused with the much larger rocket boosters which are disposed of shortly after takeoff.
- syaorankun, on 07/05/2008, -1/+27Reminds me of this image I found on Wikipedia that has Wernher von Braun (father of modern rockets) and the Saturn V rockets:

Take a ***** of liquid nitrogen stored at -423 degrees F, mix it with liquid oxygen, pump that mixture at the rate it would take to empty a family size swimming pool in 25 seconds, ignite it and burn it at temperatures that reach 6000 degrees F, direct that through a de Laval nozzle, and you get the formula for an engine that produces 400,000 lb/f of thrust. Multiply that by 3, add 2 solid rocket boosters at 3,100,000 lbf of thrust each, and that's what you need to get the shuttle up to 17,500 miles an hour, which is how fast it needs to go to maintain an orbit around the earth at 242 miles above sea level. Jets work entirely different, most modern jet engines are actually turbofans which are jet engines that power an enclosed propeller or "fan".
Here are the different types of jet engines.
The first jets were mainly these:

Nowadays most jets work like this:

Helicopter and M1A1 tank jet engines like the ones you work on, are turboshaft engines, which are basically jet engines that are built to maximize shaft power, like this:
http://en.wikipedia.org/wiki/Turboshaft
Some planes that use a combination of jet engines to power conventional propellers work like this:

You might want to check out those articles, they're worth seeing for the diagrams alone. - richardstaboner, on 07/05/2008, -1/+20Is that a sweet mullet I see in the first pic?
- besheer, on 07/05/2008, -2/+21Well thank ***** you're not my aircraft mechanic.
- corr, on 07/03/2008, -0/+19it's not the size that matters, it's how you use it
- denizen42, on 07/05/2008, -0/+17You should see the gas tank
- inactive, on 07/05/2008, -1/+15It gets bigger when it gets fired up.
- MattFid, on 07/03/2008, -0/+13I want to be you.
- Chieffancypants, on 07/05/2008, -2/+15There's an engine in this picture? I'm far too distracted by the fanny pack
- jmo14, on 07/05/2008, -0/+10must be your years of rocket engine design exerience talking
- MrStabby, on 07/05/2008, -0/+10I'm only digging you up so someone will explain...
- protoopus, on 07/05/2008, -0/+9i'll bet those cables cost an order of magnitude more than monster cable, as well.
- edwartica, on 07/03/2008, -8/+17Working on editing out the people via photoshop right now. As soon as I do, hello new wallpaper!
- EllimistX, on 07/05/2008, -0/+8That's what I said?
- Nubli, on 07/05/2008, -0/+7It's a v24.
- inactive, on 07/05/2008, -1/+8Jesus thats ***** scary, a helicopter mechanic who doesn't know the difference between a turbine engine and a rocket engine.
- Chainheart, on 07/05/2008, -5/+12Blue, Yellow, Green, Red, White, Blue, Yellow
- domomike, on 07/05/2008, -0/+7That baby is 37 Million Horsepower!
- KennMac, on 07/04/2008, -3/+10The thing I enjoyed most about this photo is that the word "CAUTION" is painted all over the side of the cone.
- mCanada, on 07/05/2008, -1/+7The difference being Shuttle cables can't be replaced with coat hanger's.
- apophenic, on 07/05/2008, -2/+8lmao what's with all the tie dye?
- apophenic, on 07/05/2008, -0/+5I /am/ you.
- mrinsanity, on 07/05/2008, -0/+5sad that I was thinking the same thing
- goodinohio, on 07/05/2008, -0/+5yeah yeah, save it for your girl friend.
- inactive, on 07/05/2008, -2/+6It was designed and built before all your fancy computers and calculators you have nowadays. All hand calcs. I bet most engineering students now couldn't do hand calcs without their TI-89's or HPs.
- anselm83, on 07/05/2008, -2/+6Gray socks w/ trail shoes, ill-fitting jean shorts with fanny pack, hideous shirt tucked in... yup, we've got a winner.
- AaronMan24, on 07/05/2008, -1/+5Is that duct tape??
- GliTCH82, on 07/05/2008, -0/+4Dude, you should totally work for NASA. I mean after 26 years of shuttle flights, and with the shuttle program coming to an end in the next 3 or so, they might really need you to help them with their thin and breakable wire problem on what's probably the most reliable rocket engine ever built by people.
- InvaderProtos, on 07/05/2008, -0/+4Were Cape Canaveral in Arkansas, OSHA would require "aim away from face" to be stenciled on it as well.
- joshpar, on 07/05/2008, -1/+4Wrong part, idiot.
- DeskFlyer, on 07/05/2008, -0/+3It says "Space Shuttle Main Engine" right on the engine stand.
- mrgreenjeans, on 07/05/2008, -0/+3In the background, behind the big guy holding a drink, there appears to be colored banners (or someone's laundry) hanging. Left to right: B,Y,G,R,W,B,Y.
Why it's a comment I don't know, but it made me curious. - JonProphet, on 07/05/2008, -2/+5Not bad for 30+ year old technology.
- AnalogCamera, on 07/05/2008, -2/+5These things are quite massive, we all must admit.
It's much cooler though when you see one in person. - grantmoore3d, on 07/05/2008, -0/+2Ah, so the same method I use when repairing computers..... "there's 3 screws left over...?"..... "bah, you didn't need them anyways!"
- grantmoore3d, on 07/05/2008, -1/+3CAUTION DO NOT CRUSH INSULATION
- GliTCH82, on 07/06/2008, -0/+2Right, thrust is produced as a direct result of rapidly expanding gases, but that has more to do with the controlled burn of liquid hydrogen (with LOX as an oxidizer).
- mikester540, on 07/05/2008, -0/+2Yellow, Blue, Blue, Green, White, Red
- effer, on 07/05/2008, -0/+2Im pretty sure that's Tom Cruise in the first pic.. a full grown human would have to crouch in that exhaust cone.
- db0255, on 07/05/2008, -1/+3How many cylinders is that?
- Samo89, on 07/05/2008, -0/+2yea, i knew it was smaller than the F1 that was used for the Saturn V but i did think it was a lil bigger
- TimmyA, on 07/05/2008, -0/+2Wrong. This IS an SSME. Can easily see turbopumps and the pipes used to cool the nozzles.
- Melodik, on 07/05/2008, -0/+2Used the thrust to crash links.
- jepizacar, on 08/04/2008, -0/+1nice resource....

- regression, on 07/08/2008, -0/+1I need one of those for my lawn mower.
