super charger?

[D3vastator]

is this implemented yet?

 

when I click the high supercharger the light just flashes, am I doing something wrong?

The 2nd stage of the Super charger is automatically engaged above 12,000ft (I think) You can't engage it manually.

ah no prob, thanks m8, one other thing I Dont seem to have the character appearing in the cockpit, nor can i see any other player charaters, where do I enable this?

 

thanks

[Nate--IRL--]

You mean the pilots body? That is enabled with Rshift-p

excellent, thanks a mill!

[Soulres]

ive gotten it enabled before.. i held it and the light stayed on after that,i want that super charger on so i can hear it roar!

Seems I was wrong - you can engage the 2nd stage, as long as you hold the switch. Oh and the alt for automatic engaging is 19500ft

 

For normal operations, the supercharger should be kept in AUTOMATIC mode. In this position, the

supercharger is controlled by an aneroid-type pressure switch, which automatically cuts the unit into

high or low blower as required. This switch is adjusted to cut the unit back into low blower mode

approximately 1,500 feet under the altitude at which it cuts into high blower. This prevents the high

blower from going on and off repeatedly with slight changes in altitude near the level at which the

high blower cuts in. If the aneroid switch fails, the supercharger automatically returns to low blower.

 

The LOW position on the manual switch on the instrument panel makes it possible to operate the

supercharger in low blower mode at high altitudes. This provides better range at high altitudes,

which can be used for long-range flights.

 

The HIGH position on the manual switch makes it possible to test the high blower mode on the

ground. The switch must be held in the HIGH position by hand, however, because it is springloaded

and returns to the LOW position when released.

An indicator light next to the manual switch on the instrument panel turns on when the supercharger

is in high blower. The light can be pressed to test its functionality.

you just pop open the cover, hold the switch with LMB then close cover with RMB.

sweeet, thanks

[WildBillKelsoe]

sweeet, thanks

 

be careful though, below 5000 feet there is no need to operate in hi blower. performance using FMP would yield the same output.

Oh and beware, engine damage modelling is vastly more intricate with the next update.

It is on all the time, it just switches between low and high gear. The high gear demands more torque from the crankshaft, so it is wasteful to run it at low altidudes, where even the low blower setting provides more than enough boost to go into WEP.

The second side effect is that the mixture is heat more at high gear that is not good for the overall performance.

Generally, the best blower must provide the boost required at certain altitude. It means that it must have something like a variator but it is not that easy. In DB-605 Germans used combined blower to avoid power loss between two critical altitudes. In Russian AM-35 blower Polikovsky guide vanes were implemented to have variable blower pressure ratio.

Any idea on what the P-51's implementation is, or does it not have this feature (i.e. no pressure governor, just the two gearings)?

It does not have. The blower has two gearings with automatic aneroid switching and a regulator that controls a throttle valve maintaining desired MP. But no blower power optimisation.

US was able to manufacture turbo chargers that do something similar to hydro variator in DB engines.

Thanks!

I am a little bit confused about LOW stage of supercharger in P-51.

 

Manual:

The Packard engine delivers approximately 1490 horse power at sea level. It has a critical altitude of approximately 14,000 feet in low blower supercharger mode and a critical altitude of approximately 27,000 feet in high blower mode. The maximum altitude is approximately 40,000 feet. The supercharger ratios are approximately 6 to 1 in low blower mode and 8 to 1 in high blower mode.

 

Is LOW stage ON from 0 ft altitude (until switching to HIGH at aprox 19500 ft)? Or there is supercharger completely OFF until LOW stage is ON at aprox 14000 ft?

 

It seems to me, that LOW should be ON since the start od engine because MP on take off can be set to 61 inHg. If there was no supercharger, max MP could be max only approx 30 inHg (the same as atmospheric pressure). Am I right?

that is not true to my knowledge.

you can engage it manually...you just have to keep the switch pressed to leave it engaged.or, if you have a hotas warthog, and assign it to one of the throttle switches, you just switch it and it will stay engaged...

 

EDIT: sorry didnt see your second post when quoting you...

PS: "Oh and beware, engine damage modelling is vastly more intricate with the next update."

when are we going to see this? :)

That is well implemented now, the engine does not tolerate mistreatment very well at all now.

After reading your post I entered the sim and tried to abuse the engine a little bit. At lowest RPM and max throttle, even playing intermittently with the supercharger and rapidly increasing and decreasing throttle, the engine didn't fail as I believe it used to do. I remember when I first flew the Mustang (unfortunately don't remember what version) if the engine wasn't really taken care of, it would seize shortly after take off.

 

Also I noticed that the visual effect of propeller alpha doesn't seem to be modeled anymore. Looking from the side, the "thickness" of the blade seems to be the same at lowest or highest RPM.

 

Not complaints, just comments.

Nobody knows?

[sobek]

Yes, low stage is always on.
