Letting the court decide is a great move. Govt can pass ordinance or amend constitution always. B ut if court does it, it's easier . Otherwise courts get exposed for their view points driving much needed discussion on our courts. What makes you to think that courts will decide ? as usual it might j...

And there is no stage matching. Yes I agree as now Pt2/Pt6 is around 1.2 which is way too high. It has to be too around 1.05 The TET should be limited to 1400K in ISA conditions as per the GTX cycle. I am still not able to get my head around with this TET. I feel it is too low TET to be realistic. ...

if you are using 1D cooling model let me know to what level you are cooling your blades to? i mean what is the metal temperature that you are setting to.
FYI in industrial GT i have seen blearing as high as 18~20% for cooling. not sure of aero.

madhu

I am writing the equations for the engine on my own from scratch. Once I am done with all of them, I will insert the cooling model. If I find a good model before you I'll let you know. JayS, i am not a CFD/thermal guy so i am struggling to embedding the 1D thermal coling equation. however i have fo...

madhu

PS: Do remember that model used by Madhu is still not completely realistic. For example it does not account for Cooling air off take from HPC which can be as high as 30% of HPC output. JayS, I see that the cooling are tapping is just 2%-3% max of 5% at design point. https://www.easa.europa.eu/sites...

We need to look inward and honestly introspect. Sir each technology have its own complexity but jet engine is more complex than nuclear technology. Imagine u need to maintain a candle flame while you are driving at 500kmph. Thatz what happens inside GT. The air is at 0.3~0.5 Mach and u need to sust...

JayS,
I am seeing way too many unknowns to proceed further. if you have any pointers can you suggest? also please PM your mail id so that we can discuss more.

Jays, Right now i am doing it for Civil Jet engine just to calibrate my calculations. But i see that there are too many options to choose from. To do s reverse engineering. I might need data like hub/tip radius etc. The option are so many that it difficult without cross check every time. Let me see....

That's correct. Bypass mixed with core flow starting just before A/B until almost at the start of nozzle. Without such arrangement, exhaust pipe and nozzle would melt with A/B on.
