So you recognized that you were mistaken? Good for you, chap.

 

Did you even read what I said?  Lift coefficient in the subsonic, incompressible regime is defined by the airfoil and its AOA relation. The total lift FORCE will increase with speed but NOT the coefficient.

Of course it is, because AOA changes lift (Ya) and lift is part of the equation i wrote

Coefficient of lift (Cl) is a value without units. In normal (subsonic) airflow it only depends on the angle of attack. You can think of this coefficient as wings potential do produce lift. Airspeed is the one that "quantifies" this potential. So for 0 airspeed it does not matter what is the value of AoA, as the lift produced will be 0. On the other hand for a constant speed the lift will increase as the angle of attack increases until the AoA reaches its critical value. This is the maximum AoA at which maximum Cl is experienced. Above that angle there is no lift, regardless of the airspeed - this is a stall condition and we all know that in this kind of condition there is no lift.

If I recal correctly from what I've read somewhere, what Cmptohocah mentions is that the Germans themselves de-tuned the engines a little bit to increase their lifespan, after already having them in service.

 

So it might mean that, they arrived originally with their "full power" as per what is stated on the manuals...

 

IIRC the Soviet and the Warsaw pact export versions of the MiG-29 had two selectable power settings for their engines(to be set by ground crew before flight) - "normal" or "combat", where the latter came with some rather strict limitations in terms of much it could be used(only a few procent of the flight hours). This(the "combat" mode) was removed on the MiG-29B non-warsaw pact export version - i.e. always running in "normal" mode.

 

The East German MiG-29s were the warsaw pact export version with both power settings, but after having "inherited" them, Luftwaffe changed the power output of the settings, so that the "combat" mode now corresponded to "normal", while "normal" became a "reduced" power setting instead.

 

So the full power was still available on the "MiG-29G" - they just ran the engines on the reduced setting most of the time in order to extend their service life.
