Help me identify this turbine

Hello JATO members. This is my first post. I was wondering if someone could you tell me what this is exactly. I will try to attach photos.

I see: "Microturbo", "...de Rupé Toulouse", "Saphir 1", "Reference 0060", "date de fabrication 9.68"

Looks like a Microturbo APU type 006 "Saphir 1", probably a small air producer similar to this: www.gasturbine.pwp.blueyonder.co.uk/saphir.htm

Here you can buy a 100 paged service-bullitin for 10 euros. www.lindbergh-aviation.de/product_info.php?info=p10742_microturbo-apu-type-006--saphir-1---service-bulletin.html

Thanks for the reply. Do you know much about this turbine? Is it similar to the TRS18? How much thrust do you think it will produce?

Hi flyhilandsoft

I don't no about these turbines, I just google it!

From what I can read & see, those turbines are not that similar.

• TRS18 - Is a small turbojet, built for jet propulsion. en.wikipedia.org/wiki/Microturbo_TRS_18 and www.gasturbine.pwp.blueyonder.co.uk/TRS18.htm
  
  
  
  
• Saphir 1 - Is a small gas turbine with a oversized compressor wheel, built for starting a another & bigger jet engine(s). 
  
  

Also called as ASU (air start unit) , APU (Auxiliary Power Unit), air producer, air generator, these turbines are not built for jet propulsion.
Because these turbines has an oversized compressor wheel they bleed some (actually a lot) of air from the compressor & the bleed air is connected to a 2-way valve control:

1. Valve 1, is dump valve, air is dumped to the atmosphere when valve 2 is in closed position, to avoid compressor surge.
2. Valve 2, is for air delivery to another jet engine for starting via a air hose connection. When valve 2 is in open position the valve 1 is in closed position and vice versa.

Here is a similar unit in action.


If you want to be creative, maybe you can use all the bleed air to provide pressurized air to a DIY external afterburner-like/combustor to make jet thrust! 
But I am not sure if these engines can handle prolonged runs without modifications, I guess it could easily overheat.
