Steel Jaw Posted June 29 Posted June 29 How to know what setting needed at any given time? "You see, IronHand is my thing" My specs: W10 Pro, I5/11600K o/c to 4800 @1.32v, 64 GB 3200 XML RAM, Red Dragon 7800XT/16GB, monitor: GIGABYTE M32QC 32" (31.5" Viewable) QHD 2560 x 1440 (2K) 165Hz.
razo+r Posted June 29 Posted June 29 Look at the oil temperature. If oil gets hot, open the oil cooler. If oil gets cold, close the oil cooler. If you are slow with a lot of power, open cooler in advance may help. Same but reverse if you are fast with low power, closing it may help. Also helpful to know the OAT so you can judge it a bit better. 2
GTFreeFlyer Posted June 29 Posted June 29 If you are the learning type, that, and the use of all the coolers, is laid out in the manual really well to help you understand how it all works and when to use them, and how much to use them. Can’t remember if I saw it in the DCS manual, or the real world manual. I spent one morning reading while eating breakfast and it was totally worth it. Just wanted to let you know where to find it in case you overlooked the manual as I sometimes do, especially with all the YouTube content out there.

felixx75 Posted June 29 Posted June 29 (edited) So far, it has not been necessary for me to open the oil cooler flaps at all (regardless of which engine settings were used), which is no wonder, as the oil temperature dynamics are still WIP. Edited June 29 by felixx75

Same. Also, I read a corsair manual and oddly it said nothing.

The manual doesn't show a closeup of the combined gauge showing precisely what is what. I have still not been able to figure out two of the three indicators on that combined guage. The one on the right is clearly fuel pressure. The one on the left behaves like oil pressure due to it being high on startup and low after engine warmup, but it has a red line denoting "90" when max oil temp is 90C. The gauage above has a red line somewhere around 110 or 120 when max oil temp is stated to be 90C, and it doesn't react at all to my oil cooler flap settings, leading me to think it's the carb temp. But then it doesn't react to my intercooler settings either.

At least that's my take on it as the top one is labbeled with the C degrees sign.

Good question, since it's a R2800 like the Jug, I thought ( however misguided) that the Oil Cooler and Inter-cooler flaps, should probably be set at mid point or ''Neutral" like the Jug. But I honestly have not seen a difference in temps doing it that way. Only the cowl flaps have made a difference in any temps (Cylinder) from what I've seen. It's early access, so who knows what works like it's supposed to. Sempre Fortis

Any idea where there's disagreement between the manual stating max 90C and the red tick/blue zone on that gauge being in the 120s? That's throwing me off.

That's throwing me off. I don't know, but I would assume that this is due to the use of different sources for the aircraft itself and the manual. The plate with the engine limits on the left also shows the wrong values, namely those for the engine without water injection, although we have the "D" variant, which has water injection. 1

At least that's my take on it as the top one is labbeled with the C degrees sign. We need some clarification on this but I believe the top gauge is carburetor air temperature (CAT) and controlled by the intercooler flaps which uses the carburetor air temp warning light. Notice the low temp limit reads -50° C. This is too low for engine oil... The oil temperature operating limits for the F4U-1D Corsair, powered by the Pratt & Whitney R-2800-8W Double Wasp engine, are as follows, based on available technical data: Normal Operating Range: 60°C to 85°C (140°F to 185°F) Maximum Allowable: 95°C (203°F) for short durations, typically not exceeding 5 minutes during high-power operations like takeoff or combat. Minimum Before Takeoff: 40°C (104°F) to ensure proper oil viscosity and engine lubrication. The normal operating limits for carburetor air temperature in the F4U-1D Corsair, equipped with the Pratt & Whitney R-2800-8W Double Wasp engine, are typically: Normal Operating Range: 10°C to 38°C (50°F to 100°F) Maximum Allowable: 40°C (104°F) for brief periods, to prevent detonation or power loss. Minimum: 0°C (32°F) to avoid carburetor icing under certain atmospheric conditions. I think the top gauge is more in line with carburetor air temperature limits.

Mike Busutil Posted June 30 Posted June 30 Cool, if the manual is 100% correct than we have the R-2800-8 engine and not the 8W engine... [sIGPIC][/sIGPIC] Checkout my user files here: https://www.digitalcombatsimulator.com/en/files/filter/user-is-Mike Busutil/apply/
felixx75 Posted June 30 Posted June 30 If we have a F4U-1D, than we must have the -8W. All -1D's came with water injection.
Mike Busutil Posted June 30 Posted June 30 We all know we have the 8W... [sIGPIC][/sIGPIC] Checkout my user files here: https://www.digitalcombatsimulator.com/en/files/filter/user-is-Mike Busutil/apply/

For some passages in the included manual the wrong sources were probably used, nevertheless the included manual also describes the instrument with oil temperature, oil pressure and fuel pressure. There is also a corresponding error in the cockpit. The plate with the engine limits (left wall) shows the data for the -8 instead of the -8W.
