  1. Our M1 Abrams tanks have turbine engines running on whatever fuel they can scrounge as they move along.
  2. Well I wouldn't because of course the older engines had problems, and most of them at that, but some people like to compare old aircraft engines, some even radials from the 30s of last century, with the current crop, the inference being the current ones are all good.
  3. Phil Irving certainly got it and you certainly get it when you start building race engines to pump out 2+ x the original power because you HAVE to do something. What you are talking about is dissipating the heat outside the combustion chamber; what I'm talking about is dissipating/passing through/rapidly cooling the combustion chamber before temps of 1000 < 2500 deg C can melt anything, inlcuding valves.
  4. But we don't compare Kia, Hyundai, Toyota etc with Austins.
  5. Austin’s used to get about 30,000 miles before they needed rings and bearings.
  6. There are plenty of joysticks in GA. You're right about a low-energy aircraft; the extra time and cost required for incident-proofing in all weathers as against a zero wind flyer,is likely to put a pilot going for a CPL out of pocket compared to a C152, PA-28 or C172, and the whole culture is different to GA so a lot of re-learning is involved, but if you intend staying with RA and low-energy they will make you a better pilot.
  7. You're talking about the outside of the engine, not the combustion chamber where the temp can get to 2500 deg.C 2510 deg wouldn't make any difference.
  8. I'm basically saying the same as you; a 10 degree increase in ambient will produce a 10% increase in nett heat. If you get a 200 degree in nett heat it's not the ambient.
  9. Power demand will raise combustion chamber temperature much more and much faster than ambient. Leaning off will do the same.
  10. No, but doesn’t mean. VET structure isn’t possible also. It doesn’t have to make you the richest person in the universe.
