DD_Fenrir Posted November 15, 2012 Posted November 15, 2012 Had two engine failures in a row doing the Campaign NavEx mission; you know the one that takes you on an hour flight up through overcast to Angels 30 and back down to a little airfield t'other side of the mountains. Anyway... Figured out I was letting my coolant temp get too high. Using the manual open on both oil and coolant helped keep things in check, along with careful power settings and making sure I wasn't climbing too slowly helped, and made it to Nadzik for a flukely nice landing! It does however, beg the question, what the dickens is the use of an automatic setting for radiator controls if it doesn't do it's job? I noticed with my coolant temp nudging the wrong end of the green saftey marker that in automatic, a quick jump to F2 showed bugger all in the way of any automated process of opening my radiator; is this a bug, or were the real thermostats in the P-51D as diabollically crap as this behaviour suggests? Considering the manual says continuous 2700rpm @ 46" MP, I was struggling to keep the temps in the green - automatically at least - at only 2400 @ 36". I could understand if I was caning the motor in a slow speed climb and the auto had already opened the rads fully if I was not getting sufficient cooling, but the fact that auto doesn't seem to open them enough, if at all, seems a bit... well.. disingenuous to say the least! Thoughts?
Mar Posted November 15, 2012 Posted November 15, 2012 I remember hearing about a bug that makes it so you have to toggle out of and then back into automatic mode for it to work on either radiator. Try that maybe? From the shadows of war's past a demon of the air rises from the grave. "Onward to the land of kings—via the sky of aces!"
sobek Posted November 15, 2012 Posted November 15, 2012 The green arc on the oil temp gauge does not correspond with the real operating range, that is why the control keeps the oil temp close to redline. That being said, the damage model might still need some finetuning. Good, fast, cheap. Choose any two. Come let's eat grandpa! Use punctuation, save lives!
Suchacz Posted November 15, 2012 Posted November 15, 2012 If I remember it good, that you must climb to 35,000ft. Can't be posible, that the engine overheating is caused by freezing conditions up there? I had problems in this mission too, but I managed to save the engine and complete the mission by moving the carburetor/ram air levers. BTW, is windshield freezing modelled? I think that it isn't...

Sorry, but i don't understand. :huh: I had problems in this mission too, but I managed to save the engine and complete the mission by moving the carburetor/ram air levers. You are not supposed to use those unless the ram air intake is blocked. Using hot unrammed air is prohibited above 12,000 feet. Good, fast, cheap. Choose any two. Come let's eat grandpa!

-Mop- Posted November 27, 2012 Posted November 27, 2012 Sounds like as if it was another symptom for the the same problem described in another thread... here: http://forums.eagle.ru/showthread.php?t=98169
