The big problem the Air Simulation community has faced lately came right of this : misunderstanding of NACA tests and adjacent airfoils theories.
This had lead several individuals think they can take the fore front of simulation expertise with simple mathematical rules on hands showed (rather agressively) has powerfull and superior computing tools (can you see what I am finger pointing ?) .

The big problem we face is the overall understanding of aero principles and history of flight that are the only grounds where we can make judicious balance btw what can bee estimated mathematically at lobby level and real flight phenomena that are (supposedly) well known.

Yes you have understood my meaning : "Aerodynamics issues" are only "minor problem[s]" in the hands of the so called "Experts".

Hopefully many real flight charts are available around witch CoD devs could build other airplane characteristics.

Sadly many aficionados of one or another plane think their favorite mount is such unique that it can't be compared or extrapolated from an other one.

All is about balancing unless you want put several hundred of thousand of dollar in it.

Jane's in the past hve alrdy done such work. I can't understand why we did drove down that dead-end alley.

CFD is getting cheaper all the time. GIGO applies of course, but it's pretty good if you use it properly, especially in conjunction with known aircraft performance data.

The biggest limitation at present is the aeroelastic side, because that's much more computationally expensive. But it's very important; for example, a totally rigid CFD model of the Fw-190 would have a much more benign accelerated stall than the real aeroplane because the real thing's wing gets washed in slightly under load, promoting its well documented tendency to flick out.

If Moore's law continues to hold then ever-increasing fidelity will be possible. However, it's not obvious that there will be much of a consumer market for it, given the huge amounts of work (and cost) inherent in the generation of such complex models.

I never can get my water under 85C without a long dive, and rarely do I get it over 95 (scared to tbh). It seems to take 20-30 seconds for water to change at all (fast if you think of the numbers, but while dogfighting, an eternity) However, oil temps can range anywhere from 40C (again, open rad, diving, low throttle) to 90C (pushing hard with rad 1/2 open) quite quickly, around 10 seconds to overheating and blowing gaskets.

I've never looked it up, but I think its pretty accurate, as the oil is inside the cylinders/crankcase, but the water is in the engine case itself, and maybe even cooling the oil cooler, which would account for the delay/more stable temperatures.

That's the question. IMO water temp. does not change enough when changing alt, changing power settings or radiator position. I read storys about 109 pilots who had left their rads open during a dive which lead to a "frozen" engine. In game you can try and dive with throttle in idle position and rads fully open. It's not possible to significantly cool the engine.
Maybe someone has data on the subject or real life experience with aircraft engines.

I think this was implemented before they removed the shaking issue.

It should be possible to cruise an aircraft at a reasonable altitude with the radiator flaps fully closed. The combination of high speed and moderate power (AND low temperatures in the simulated region) will allow for sufficient cooling.

All I manage in any CoD aircraft is a ruined engine 20 seconds into a 'Quick Flight' if I forget to immediately open the Radiator Flaps.

To the OP: The issue you describe could also be related to your propeller pitch setting and the speed you travel. You can overspeed your propeller in a dive and effectively cause the engine to cycle so fast that it shakes/burns to oblivion.

Pitch control in a dogfight is half the battle - Keep the RPM below the red line at all times

[TomcatViP]

I do confirm. You might hve to watch closely your rpm that can be dropped bellow the recommended settings in these conditions

Hi guys. Is it correct that OIL radiator is not controllable? Or at least it seems so in the hurricane
