Stators, Combustors and Turbines - Turbine Engines: A Closer Look

Looking at some of the major components that handle the airflow as it is processed by turbine engine.
Some are from a damaged engine we've taken apart, and some are ready to be installed in a fresh one we are assembling.
The S&S Turbine Services Ltd. shop is in Jet City, Canada.

Does the stators increase in terms of the chord towards the root (fixing point)?

[AgentJayZ]

@TR3B11 no usually. As you can see in this engine, the chord is constant. All other engines I've seen are similar.

The snowmobile hanging on the wall is a collectable and are very hard to find. To hell with the the gas turbine motors let talk sleds.

[AgentJayZ]

@michiganstopcat That is a real SSR and it has almost no hours on it. I do not believe it is negotiable...

[michiganstopcat]

@AgentJayZ Awesome to see that hanging on your wall!!!! Guys would be licking their chops at the thought of buying that!!! You video is also very good, Im a stationary engineer in a power plant and we have a gas turbine generator and its the easiest piece of equipment to start up as any we have.

If you know, i would like to ask you if whole air by compression comes into the combustion liner through the holes or there is a bypass for cooling reasons or whatever?

[LarryCanFly]

@AgentJayZ Well said! Is there anything on the horizon that might extract more useful work from the fuel? Higher temps and higher pressures have been the path, right? but how far can it go?

[AgentJayZ]

@LarryCanFly There is no free lunch: simply put - two thirds of the energy obtained from burning the fuel is used to compress the air to burn with the fuel. One third is left over to perform useful work.

[LarryCanFly]

@AgentJayZ No question that most the power produced is used to driver the compressor - which of course makes it all possible. The compressor+turbine lets you burn more fuel, faster, hotter, and at higher pressures than alternatives, which is good. And really good at high altitudes where the air is thin. So to have 15k HP extra, you put 30k into the compressor and get 45k out - continuously, a great return on investment. And to think you start with 10hp, some fuel, and a spark? Wow.

[AgentJayZ]

@LarryCanFly I guess if the combustor section could be supplied with enough air at the right pressure, then it could just rage away like a rocket, without a turbine in its exhaust. Then it could drive a power turbine making about 45 thousand Hp... but you can't get something for nothing. If there's no turbine extracting the power to drive the compressor, then the combustors don't get fed, and nothing happens.
