Dear SR22TN / 22T pilots and mechanics,
I’m working on a very sophisticated software rendition of a SR22TN (TAT) for a flight simulator. It will also feature a fully custom thermodynamic engine model of the IO-550-N with Tornado Alley turbonormalizing system; for this purpose I‘m trying to aquire technical information on the turbochargers used in this application and probably only pilots or mechanics can help me with it as all other attempts to find resources about it were unsuccessful. Also 22T pilots could help because the turbo used in this model is essentially the same!
In short, I need the compressor and turbine maps to code the airflow characteristics of the turbonormalizing system. It would even help to know the model names and specifications (trim, A/R) of the compressor and turbine.
TAT was able to tell me that the turbochargers used on SR22T(N) are manufactured by Hartzell Engine Technologies / Kelly Aerospace as P/N 466304-0003 and P/N 646667 at Continental for the 22T, but rely on conventional Garrett components. Inquiries at the respective manufacturers (HET, Aeroforce) were unsuccessful, even though I’m not interested in any insight information or IP, but only in the turbocharger maps which could be derived on any test bench and are therefore shared by Garrett. I’d highly appreciate any input that could help with identifying the turbocharger model and find its physical properties. Maybe someone knows the respective specs or could have a look under their cowling.
Thank you very much for any help!
