109 slots

This decreases the airpressure around the upper side of the leading edge, and allows the mechanical springs to push the slat out. .................................................. .

So really, the slats are springloaded to open, but I don't know the exact design of the messerschmitt, nor the springforce they set to the slats to keep them from stowing. Either way it's the combination of speed and airpressure around the leading edge that allows it to deploy or stow.

Sorry, but no springs on the Bf-109 slat design .... purely air pressure driven.

Which is why you'll see some photos of 109's on the ground with slats retracted, and some with slats extended. If they were spring driven, the slats would always be extended on the ground, wouldn't they?

Salute

To suggest the 109's in CoD are not going to have slats is nonsense.

IL-2 is ten years old and Oleg modelled slats on the 109's in it.

Why should he suddenly decide to go ahistorical and not include them?

Silly thread.

I agree with your theory, like I said, I'm no 109 expert. However I am familiar with pure aerodynamic slats. I saw a french design during my training that was easily pushable to either retracted or open, like you say about the 109.

I just believe that, for maintenance purposes and wearing, there should be some spring to "dampen" the movement of the slats so that they don't violently slam open or shut. Anyone could tell you that this will fatigue the design unless there was some buffer or spring to soften the movement. Anyways, there seems to be no springs forcing the slats to open.

Absolutely and asymmetric deployment of slats did occur and even in some cases caused fatalities.
