From the FC3 manual :
Quote:
Ailerons and flaps were replaced with unified control devices -
flaperons, wing leading edges were fitted with slats (the T-10 had no leading edge high-lift devices),
the automatic adaptive deflection mode for the flaperons and leading edge slats was ensured
providing for the fighter's "polar curve envelope" flight concept.
Also on Wikipedia and so on.

Btw, the later T-10 version did have leading edge flaps.
Nope, sorry, I am in no way an expert. I was just answering to your question about where one could have read that information.
On that note, I'm out.

Leading Edge Flaps(LEFs) is the same thing as "slats" and yes the Su-27 has them

It doesn't have separate trailing edge flaps and ailerons - the functions of those are combined in single devices known as "flaperons".

The initial T-10 design you were referring to was never put into service - it was a pre-production design that was abandoned because it didn't meet the performance specifications set out for the aircraft. Subsequently the aircraft was completely re-designed and assigned the factory designation T-10S, under which it entered service as the Su-27 in 1983-84. This is also the reason why the "baseline" Su-27 got the NATO designation "FLANKER B"("FLANKER A" had been assigned to the abandoned initial design).

The "baseline" Su-27 was produced in two sub-variants; the Su-27P for the PVO(air defence forces) and the Su-27S for the VVS(airforce) - the designation suffixes are rarely used though and the difference between them basically boils down to the former having no air-to-ground capability.

So the Su-27 version in DCS is the Su-27S(T-10S).

Macerick explained the difference well. F15 is energy fighter and flanker better in close combat. Thats fundamental difference and RL fact. Yenkee knows it, Commies knows it. DCS is wrong.

We call that Kruger Flap .
No hinge rib or driven rib. Only flap on articulated hinge with actuators . Less eficient than slats for sure.

Perhaps. But if the function of a slat is to allow air to flow from below the leading edge to the top of the wing to increase allowable AoA, no gap means it would function similarly to a Kruger flap, wouldn't it. Different name but similar effect.

The function of the gap is To create an air mouvement coming from intrados To stick the stream more eficiently on the top skin or extrados. You cant do it with kruger
