Lavochkin fuel tanks

[Bodhi]

Pyro,

As for wing hits in the La series, the only loss of a tank there will be that wing's tank fuel load for a few seconds till it seals... (maybe base it on a formula involving numerous hits to the tank for a total loss) THe "one way valve" that prevents the main tank back flowing to the wing tanks would prevent any further fuel loss from the rest of the system as it basically isolates the wing, but would still allow the fuel to continually flow to the main until the wing was dry.

Actually my point was more for stuff pyro may already be able to model...... I had not considered self sealing tanks as a modelled feature with the game........... if HTC does then the issue is so complex i would leave its depth of complexity up to them............

It gave pyro the choice of showing the fuel in its different tanks and modelling the wing tank hits such that when he decides they are holed (cos some calibre of stuff will do it) than they do not drain all the fuel.

Further it enables him to model the FM dynamics caused by the weight  of fuel in the wings at various fuel levels.

Tilt,
The LaGG-3 had similarly protected tanks as the early La-5 ie tar soaked  cloth covering (and exhaust gas system). This can be verified from the LaGG-3 manual, FAF report on LaGG-3 and German report on LaGG-3 structure. If compared  for example to the thick rubber back of the Bf 109, it was not as good protection but certainly good enough against small caliber weapons.

The FAF museum has the tank of the SB-2 which is built very same way.

gripen, do you have more detailed informations about the tank protections of the 109 (and maybe 190 too) ?

This consisted of two wing tanks and a main fuselage tank (forward of the wheel well).

 

My error the tanks were in  a row which placed the fuselage tank just to the rear of the wheel well...........its above the square panel you see on the panel lines

Niklas,
I have no special knowledge on self sealing tanks. Probably the best source on the Bf 109 tank system is "Luftfahrt Internatiol" No: 27. Good pictures and descriptions and even cutaways (Bf 109F).
