correct as-is Unlimited WEP

[razo+r]

The Manual says, Max. allowable time for Take-off / War Emergency Power (1.4/2700) is 3 minutes. When I test this in game, I can WEP the whole flight long until I run out of fuel. 45 Minutes pure WEP.

 

That is a 42 minutes difference. Shouldn't something have happened to the engine within those 45 minutes or am I missing something here?

No damage model for radial engines.

It is the same for the P-47.

[razo+r]

I hope they will inculde it with this update...

[razo+r]

I must say I am disappointed.

 

The Newsletter says:

To prolong the service life, compliance with manifold pressure levels and RPM recommendations and limitations are mandatory. If not respected, you run the risk of serious engine malfunction, and you will probably be looking for a suitable emergency landing site in short order.

 

So of course I jumped into the Anton, smashed the throttle full forward and waited. After 45mins of full throttle, my engine died, because I ran out of fuel...

 

I do really hope this will not be the new standard for DCS... That would be really, really disappointing.

@Razo+r Where you found this 3 Minutes for the A8 dont know...actually they give permission for 10 Minutes increased Emergency Power for 1,58/1.62 how this worked out when the Engine blows after 3 Minutes on 1,42 ATA? Was perfectly fine still with the Emergncy Power in Limits, this overall will decrease the Lifetime of the Engine in Hours not Minutes but will not blow immediately the Engine in to Pieces.

 

Bevor the Update Oil Temperature was to low and Oil Pressure allways high thats right, but after the Update the Engine is working Spot on.

Tested that my self few Minutes ago, full Power Climb 6,5 Km where the Engine reached its Peak between 85 and 90 Degree Oil Temperature on full Throttel Altitude.

Cooling FLaps Position 3.

 

Same goes for Full Power Level Flight, reached its peak by same Oil Temperatur with Cooling Flaps Closed.

 

Test for Engine Temperatur with Increased Emergency Power with Detailed Settings.

1.4 Ata limited to 3 minutes according to the manual:

 

 

I must say though I didn't test it at 600m only, it was more between 100m and 2000m. RPM were at 2700 at all times and MP most of the time at 1.42.

 

But my oil didn't go above 70C either as far as I could observe, cooling flaps in default (closed?) position.

The Test only give Temprature on the Peak Oil Temperature, either Level Flight or Climb in 6,5Km. For Climbs Cooling Flaps on Position 3, for Levels Flights in 6,5km Cooling Flaps closed. Air Density start to fall of, therefore overpressure in the Engine Compartmant drops Temprature is rising.

 

On Ground Level cylinderhead Temprature is only 165 Degree so 70 Degrees Oil is plausibel, on 6,5 Km the cylinderhead Temp is near 220 Degree and 85 to 90 Degree.

If you change the prop pitch and go above 2700rpm you can damage the engine now but it seems there is no time limit for the wep and I don't know if it should get one or not, the time limit seems to have been set because of the temperature of oil and engine and not of the engine limit (rpm, ata), they cleared higher ata for higher time without big changes on the engines, there is no injection so hard to tell

Is the Fw 190A slower after the update?!

[tapi]

I think not at least at sea level and at 6000 m.

[jules9393]

Something has definitely changed for the engine with this last update because now my engine blows just on taking off in mission 2 of 'Horrido' with drop tank and rockets loaded and I have never experienced that before.

Did you warm up the engine after start up?

[jules9393]

Yes absolutely.

[tapi]

Just finished Horrido! mission 10 a no problem with A8 at all.

Please supply a track if you have one. Thanks.

As far as the original post, we are doing some work on the affects of abuse and overheating on the engine. Understand that the limits in the manual are taking into account that the real plane would be used again, probably daily. Every time you jump into a plane in DCS, its brand new, no wear and tear. The Anton is an incredibly tough engine, and shouldn't be easy to blow up unless you are really trying. This will be a bit of a shortcoming though for any radial engines, we can abuse them more as we know there is no worry about engine life over time.

I think you cant overheat Fw109's engine. I tried but with no success. This fan at the entry of cowling does great job in cooling engine.

Looks like this does not apply to P-51's engine, had plenty of engine deaths even when restricting engine chart (i'm thinning about WEP use). Looks like UK/US engineers overrated those limits.

The 190A should be tough to overheat, but not impossible, we are working on it. You really have to try, running at high speeds, the engine will stay pretty cool. Its an impressive engine.

That could be a nice future feature. Accumulated engine wear and tear during the course of campaigns, or select an engine state other than factory fresh randomly a mission start. Something similar to the birdstrikes or random systems failure options we have now. Maybe this could be done via an mission editor setting, where you can choose the number of hours the engine was already running in the past, with a consequently increased likelihood of failure when abused. 

[NineLine]

I would love to see this for a dynamic campaign mode for sure, people would have to respect the limits more.

I tried it running on the ground, i wish for ability to latch plane to ground for full engine runup  in ground crew option.

I remember yo-yo saying that this cooling fan takes significant amount of power from engine, it could be possible that that engine can run full power when stationary.

I was thinking about this engine limits, airframe limits of the planes which are you modeling. A lot of players try things which in RL were never tested. Pls tell me who in RL exceeding Vne for example, who runs engine at max power for 1 hour when engine chart says the 15min is limit. How to determine  what exactly happens when you exceed those limits. This is very difficult or even impossible to do.

But one thing should be done for sure. if ED team decide that those limits are set at the verge. Example if you exceed 5 min limit for engine power setting engine blows up, pls do it for all planes.

it is very confusing when one plane can run full power indefinitely, when other blows up quick when  limits are exceeded, when limits says otherwise .

I am intrested in buying the A8 because of the cooling Fan. Engine can run full power on low speed without overheating, the cooling fan is a unique engine design.

 

In my opinion the engines in DCS are way to fragile, sometimes i got the feeling the engines would never pass the test bed to leave the factory. Its a engine, how much hours a engine can run? Is someone replacing his car engine after leaving the highway? gues NO. A engine.. is a engine, not something you throw away after a singel use.

 

The engine in my car was able to run a hour with a drained cooler in summer on highway, a hose was broken. No engine damage after repair.

My cooling fan was broken during a whole hot summer, engine turned off alot from overheating, back on after a couple of seconds. No engine damage after repair.

Last time when i had a igniton coil maulfunction i drove strait to the garage with detonations. No engine damage after repair. Engine still running.

The engine in my car is Mad Max.

 

We repair our cars when something breaks, but aircraft mechanics taking much more care and replacing things before they break. This birds were racing machines with constant maintenance.

A engine can take a punch frome exessive overheating YES.. but the question is.. how much punches a engine can take? ..and i dont believe a engine dies from a singel sucker punch.

Don’t mess with the engine too much. The 190a had a beast of an engine it shouldn’t break down or overheat easily.  The engine could be pushed. It was a great design.
