GR 130 First experience.

[MadRay66]

Hi Spotter, nice to see you're also building a GR130. However, just a word of caution: I wouldn't use the modified bearing. Under axial load the "gap" might cause a vibration to devellop and/or destroy the ceramic balls (and thereby the entire turbine).

Good luck !

I thank you.
In the past I had looked and looked at your site, you do some exceptional work you are very good, I only did a test of construction of the bearing, certainly as you do it is safer but also more difficult because you have to calculate well how much to narrow the central ring , one thing I did not open,
you put the central ring in the freezer and the outer ring warm it?
greetings Alfonso

Hello Gerald,

I started to build a KJ66 from Artes, but I find later your GR130, as I have already made some parts, I'm building a KJ66 - GR130 hybrid.
I read your modification of the diffuser to change the angle from 14 to 13 degrees is my sketch is good?

I have bought a T04E, https://fr.aliexpress.com/item/3295..._list.0.0.6c355e5bIsSIDk&gatewayAdapt=glo2fra, looks like the same you used
could you send me the profile file, I can't download it from your site?

Here is the firsts parts

Thanks for you help

Double post, sorry

Here is the right link for the T04B compressor : www.gerald-rutten.nl/GR130%20compr.casing%20radius1.dwg

Hi Joachim
You should change the spring in the tunnel to the front. If i see it correct, then it‘s in the back now!

Only out of curiosity what if one uses the 2038 compressor, the wedge diffusor and the gr 130 combustion chamber?

 

[Gerald Rutten]

That could work but you need to change the diffuser radial blade angles and wedges. Just copy/paste wouldn't work. Maybe extend the current KJ66 diffuser design radial wedges into full wedge. But that's trial and error....

Hi Joachim, sorry,I haven't been here too much lately.... Your diffuser angles look good, might work. But again, trial and error!
