hello all!
i tried to calculate out this HRR for my HOLSET HX60W that i convert into a
turbojet but i get stucked on the maths here,can someone please try to help me
calculate out my HRR For my engine.
technical data is as follows: inducer 76mm OR 2,99213 in
:HUB AREA 20MM OR0,7874 in
flametube diameter= 150mm OR 5,9055 IN
FLAMETUBE LENGTH= 35CM OR 13,7795 in
maybe that flametube/combustor length is a bit too short then please help me
calculate out how long it should be to work
thanks for any help/stephan

I think thats similar in size to what i'd like to run. I look forward to your results!

How many will you use? You need a fairly large volume so the foaming return oil has time to settle before it reaches the suction line again, 4-5 L at least.

That should do it.  Make sure to fit an oil cooler with a fan if you intend to run the engine for any longer periods, the heat builds up very fast and with "only" 5 litres of oil things can get smoking hot in only a couple of minutes. |

how big oil cooler do one really need?, say a turbine of my size is there any formulas to count out expected need for oil cooler?

you would have to know how much heat is being put into the oil in order to answer that question properly
That will probably vary greatly from turbo to turbo... either way, it's not a trivial amount...

I don´t think you will see higher temps than 150°C or so, it all depends on how high P2 you are running and where on the efficiency map the compressor is working but I assure you that you won´t get anywhere near 400°C. But make sure to take into acoount the heat soak after engine shutdown, there will be lots of heat creaping out from the massive turbine housing. Might be best to get it welded after all, a quick job for anyone with an AC/DC tig. |
