Hi Gerald Sorry for My late in the answer.....we changed compressor using one with 7 blades, we enlarged cc holes to 5,5 and checked the kero...
Great result EGT-RPM! We are Very happy of that and we are glad to show you!: http://youtu.be/SJ4zA_Ywkvo After a Lot of work and study we...
It is very light....it flyed many years ago with 6kg pulsoreactor 's thrust. ....now it is setted for turbine fly.....without fuel and turbine...
How can we increase pressure?
[media] Idle temp (44300) 598-609 degrees 83000 rpm temp 700-720 We will modify a litle bit more the exhaust cone and Probably we will...
We modified the cone serching for a better result. ..this is what we obtained :
Very Clean explanation Gerald....is it possible that our flame diameter is bigger? We tried with a 51mm diameter without bullet but we saw a very...
Thanck you Gerald but I can't find in the past posts: what you mean when you Say "Recalculate the exhaust surface"....is there any formula i can...
We putted exhaust cone : This is the result http://youtu.be/1b80wQoR4XQ What is the exhaust cone diameter you use in your GR130? It is a litle...
To be precise we enlarged 0,5mm only half of the 5 mm holes doing Just one yes and one no (5 mm, 5,5 mm, 5 mm, 5,5 mm , 5 mm, 5,5 mm etc)...it...
Very very good, we modified the needles and we made them touch the tubes waĺls. We made holes 0,5mm (from 5 to 5,5) and the result is...
Not a Big problem to solve thanck you but I thing that this is not the reason why temp is 800 degrees at idle and rpm doesn't go up. Probably we...
Hello everybody, we tryed the new cc made with 5 mm holes like was in the original Project and with 12 needles 0,8 external 0.6 mm internal...
Very impressive Gerald We are steel working on the 130 and here some fotos of the new combustion chamber [IMG][IMG][IMG][IMG][IMG] We are using...
Can you please tell me the material you use for the cc 12 tubes? Inox Steel is good? And which is the correct 12 tubes diameter?
How you make it? You work on carburation (compressor, intake cone, inition needles, cc and exhaust cone ) or you modify fadec program?
Thanck you Gerald I know you have to answer to many questions and GJ and Ger give me very usefull suggests. ... We will listen your precious help...
Thanck you for your evaluation. ..we will build another cc as Soon as possible using needles iniectors diameter 0,8 mm, and making cc holes of the...
