Can't blow or damage engine.

[Alladyn]

I wanted to brake my engine in D-9 and in P-51.

 

Funny enough, on p-51 full throttle and prop, on d-9 auto full throttle.

 

I read somewhere that people are braking theirs engines very fast, and especially d-9 on low altitude.

 

I flew, and flew till my fuel ends. No blowing up what so ever.

I flew straight p-51 ~350-400mph and d-9 ~600-650kmh on alt 10-200m

 

ofc sim settings, and instant action, free flight

Did I something wrong?

Hmph, I think not only requiring high stress, it is probably randomized as well.

 

Once, engine on my Dora died 2 minutes after takeoff, full power with MW50. Although there have been dozens of similar situations.

You will hardly break it while flying fast. Try turning at 300km/h or so. The reason why most people break engines is overheating, which happens because:

 

1) not enough airflow over radiator while flying slow on full power for too long

2) lagging automatics of radiators (if you fly at high speed for long enough, your radiator will close, however if you bleed all the speed suddenly, it won't be able to open up fast enough to cope with sudden change of airflow and spiked temperatures).

what was the outside air temp? cowls fully open? what did the temp gauges indicate?

Sometimes, I throttle up the P-51 right when I'm taking off and BOOM!!! Engine freezes. Sometimes, after a minute or two in the air, same thing. Funny part is that if I'm just working on ground attacks or whatever, I start the mission with plane already fired up and ready to go so I know that it's set up properly. It doesn't take all that much to stop the P-51 in it's tracks.

 

FWIW when I first jumped into the DCS P51-D from IL2 and Aces High I thought back then that it'd be a piece of cake. I've been wanting complex engine management in a prop sim for years and when I finally got it it took me ages to adjust. Now, I couldn't imagine anything worse than a dumbed down prop simulator experience!

 

There's a valid reason that the RPM and Manifold chart is pasted on the right sill of the Mustang, and it's a good idea (rule of thumb) to stay in the green for the temp dials. Follow these two simple rules and you'll mostly be ok .. well, until the shooting starts! :D

 

Other than that it's OK to push the engine for short bursts .. but never for too long.

Thanks, I see. I thought that full throttle might blow up engine, even with cool temps. Thanks :thumbup:

I didn't use boosts./\Manual rads on d-9 100c120o./\Outside temps were set default, like on instant action free flight.

This sim is a Blast!

There's a checkbox in the settings page for random systems failures. That's a bit too realistic for me... I leave it unchecked.

 

It's easy to fry the Dora engine if you stall it in a vertical climb and don't back off on the throttle. The AI, for example, in the P-51 loves to pull up into a hammerhead when you get behind him and stall fight. If you follow him up to get the shot and stay too long in the vertical and start to stall out with low airspeed, you've got to back off the throttle immediately or watch the temps spike and the engine blow.

I'm curious if there was an overall DCS systemic reduction of piston engine failures; it seems to me that the Merlin is quite a bit more tolerant of bad handling than I recall it being a few months ago. I would chalk it up to my increased experience, but I'm pretty sure I was randomly blowing engines before when my temps were still in the green and power settings were at 50" or below, while now I can run for extended periods with 61"+ (provided that I still keep the temperatures no more than 10 or so degrees above the green)

Don't know about the Dora but I find the engine cools down more quickly in the Mustang at lower altitudes. This seems counter-intuitive as the ambient air would be warmer but it's also denser so my theory is the denser air is more efficient at carrying away heat.

I blew mine last night 15 minutes out. My engine was not running too hot or too cold, or too fast. I was at around 5,000 feet altitude. I had no battle damage that I could see in F2 view. The DoW server has random failures set. I have no idea why it blew. Maybe I took a flak hit. The landing gear came down with keypad press "g" and the landing flaps also came down which for me, is rare not to also lose the electrical system.
