    Want to learn about turbine engines ? Check out AgentJayZ (ru-clip.com/channel/UCh57rwk3ySElDpzgCDLh9KA), he has also a video about compressor stalls.

      Excellent video, thumbs up many times. Though I can't possibly understand why anyone would give thumbs down to this video. Mentally retarded perhaps, too sad, almost 1000 of them had did this already.

      The background theory to this is to nderstand convergent and divergent nozzles as well as wing flow theory

    Minor ERROR. Compressor stalls don't necessarily result in a complete loss of shaft horse power. It depends on the severity of the stall. A pilot may be able have a controlled flight to the ground at reduced power.

    I was laying some pipe and I was winding up that turbo with that all that hot compressed action and just when she was spoiling up there was a compressor stall. Damn dont ya hate that when that happens?

      @GI D - Same combustion chamber that powers the the compressor powers the "gas turbine."

      @Ed S No. The segment you point to explains that the gas turbine powers the compressor. I'm asking "what powers the gas turbine".

      If you understand a piston engine you can easily understand a turbine. They work the same as a piston engine in a lot of senses except for all the stages of intake, compression, combustion and power generation that happen separately in a single location in a piston engine all happen at the same time and in a continuous cycle in different locations in a turbine engine.
      For example, the intake and compression strokes from a piston engine are done by the compressor on a turbine engine, the combustion happens in the burner can with the ignition of the fuel/air mixture and the expansion of the gasses just like a piston engine, then the turbine wheels extract the power from the hot fast moving expanded gasses which is like the power stroke on a piston engine, then the waste exhaust exits out the back. This is a super simplified explanation of the process but every turbine engine uses essentially the same process. I hope this helps.

      The air is compressed the pipe is tapered narrower so as the entire volume of air comes into a wide hole it gets compressed through a narrower hole. The air is not allowed to hang about until it can fit through at normal atmospheres but is forces to get through this raises the pressure as it moves towards the back once ignited it expands exponentially and increases the pressure hugely which is where the exhaust gases come into play driving the entire system.

    Good video but your model is missing a set of stator blades in the gas generator. There needs to be a set of stator blades in front of the first gas turbine wheel.

    Avanti2Man! Uscgsam 3 months ago

    Why is one set of exhaust nozzles rotating clockwise and the other set rotates counterclockwise? It may have been explained but something interfered with my audio and all I could do is watch. I worked on many jet engines and also the GE T58 and all turbines rotated in sync. Maybe that was old tech and things have changed.

    Wow that's really cool. Seems simpleish, but yet complicated because the precision to make this must be incredible. Like everything from the angle of the fins to the spacing is all carefully calculated. The alloys used etc. Tons of engineering goes into this.
