Thanks for your post, in particular Bleinheim, I understand what could have happened, rads open, cold oil => failure

what does it mean when the Hurricane's engine is puffing black smoke from time to time ?

Its not burning the fuel correctly, most likely too rich mixture, or you apply too much negative G

Hello
With Bleinheim, I keep damaging the egine shortly after take off, eventually before I could eventually rool up to taking off speed. I try running the procedure, warmin g up engine, I tried various sets of mixture and carburetor heat positions, fully open, fully closed, in-between. I reach something like 200 to 250 °C for motor temperature, 50 to 60°C for oil temperature, 55 to 60 for oil pressure, apparently normal behaviour of both engines, mixture normal to rich, full rpm, full throttle, thin pitch. I build up speed, eventually take off, then get oil leakages, engines loosing power. |

ENGINE COWL FLAPS - FULL OPEN MIXTURE 100% PITCH 100% apply throttle slowly and watch so your manifoil pressure doesnt go over the maximum recommended value |

Hi,
I seem to have burnt the engine flying at 19'000 ft simply after pushing up the power a little bit. True the oil temp was only 40°C and pressure a bit high 75-80 lb per sq inch. I could manage to get running, but apparently, if one gives the engine full power for a while, it will not last long. Not an easy plane to fly ! |

At high altitudes you can close your cowl flaps a little bit (especially if on moderate power settings), since the outside air is cold enough to provide a more pronounced cooling effect.
Radials are reliable and resistant to combat damage but they do have a high workload. Imagine flying a P-47 with CEM: throttle, semi-automatic mixture, prop pitch, cowl flaps, turbo-supercharger, intercoolers (like carb heat but they can also lower the carb temps instead of just raising them) and oil coolers. Generally speaking, 220-250 is the highest your cylinder head temp should be allowed to reach. On the other hand, if you want to apply power and its below 200, you would be well advised to apply it gradually so it has a chance to warm up, or momentarily close the cowl flaps a bit and open them again after increasing power. |
