So I'm trying to do a comparison between piston, small gas turbines and large jet turbine engines, I've come up with a 0.57 pounds per hour per pound for the Trent 700 series engines, now I want to see how the others stack up.
Basically I'm wanting to understand as to why we don't seem to be able to make small turbines efficient, and if we were to just how far it had to come. I want to try to keep the formula PPH/P if I can.
What I was hoping all you bright Sparks might be able to tell me is, what would be a rough standard figure between SHP/thrust and also HP/thrust for a standard 6cyl piston non turbo. Now I know that there are a huge amount of variables so I was thinking cruise power only. I can reverse engineer the C210 and C208 figures to get PPH/SHP figures of 0.66 and 0.6 using company SOP power settings and fuel flows but I'm stuck from there
Any ideas?
