The fuel tank simulation/BF 109


Recommended Posts

Posted

Hey Guys,  i try out the new patch.The engine oft both 109 stutter and cut off , if you fly on back. Test this with max fuel. Is this correct? Is there no benefit of gasoline dricet injection?

Yes, but the fuel tanks are still depending on the plane not being upside-down all the time. Fuel is still pumped from the bottom of the tank, so if you fly upside-down for too long you should still starve the engine.

Maybe the fuel tanks and pumps could be the problem. I wrote yesterday a email to this guys http://www.flugmuseum-messerschmitt.de   Today i got a mail, that my request is being processed.Sehr geehrter Herr XXXXXXXX,

 

vielen Dank für Ihr Interesse an den Flugeigenschaften (Rückenflug) der ME 109.

Ich werde dazu Werte bzw. Informationen in der kommenden Woche aus der Technik (wie z.B. Handbuch) einholen und Ihnen dann unverzüglich zukommen lassen.

 

Mit besten Grüßen aus Manching und ein schönes Wochenende,

Once i get the informalion, i will post in this fourm.

I promise to post the anwser from Manching.

 

Sehr geehrter Herr XXXXXX,

 

vielen Dank für Ihre Email und Ihr Interesse an den Flugeigenschaften der ME 109.

Nach Rückfrage mit der Technik, kann ich Ihnen folgendes ausrichten:

 

Flugmanöver in Rückenflug sind zu vermeiden. Hierbei treten vor allem Probleme durch das Ausbleiben der Motorschmierung auf. Zeitliche Angaben über Höchstdauer/Länge des möglichen Rückenfluges sind nicht vorhanden.

Dieses Manöver wird dabei nicht von uns „erprobt“.

 

Ich hoffe, Ihnen dennoch mit der Auskunft weitergeholfen zu haben.

 

Mit besten Grüßen aus Manching,

 

So the fuel tank simulation should be ok.

It highlight another issue not simulated for any aircraft ingame. Not only the fuel circulation may be interrupted during inverted flight but also the oil, which can lead to a seized engine quickly.

 

I have not seen any exact accounts of how long inverted flight uis sustainable. Its written in a manual for the Ju 88 Jumo 211F that inverted flight in general is forbidden due to issues with the engine's lubrication system, manouvres with temporary negative Gs on the other hand are allowed.

Yak-1 with M105PF engine could sustain max 5min of inverted flight.Even direct injection of fuel doesn't guarantee unlimited negative g flight conditions. Oil distribution is the restricting factor.
