A320 series CFM56 engine's strake
Hi all,
a question concerning the engine's strake on the A320 series of the CFM manufacture.
Could anybody, for sure more expert than me, tell me what is the precise need of them and why on the A320 the strake is present ONLY on the inner side of the engine and not on both sides as on the A319?
Thanx to you all,
always happy landings!
Examples:

The strake reduces the flaps down stall speed. Besides the Airbus A-320, only one strake (inside) is used on the heritage Boeing 737's. The reason has to do with the wing leading edges, having slats deployed and the relative position of the nacelle in relationship to the wing. The strake acts like a vortex generator.

Hi there,
thank you for your answers guys!
But i don't get one thing. If the strakes are there to reduce the flpa down stall speed then why is there this difference between A319-320-321?
Because it looks to me that the construction of the wing and of the engine is the same for all the types. So the air stream, i suppose, it should be the same around the engine's nacelle and the wing. Or? So again why the need of 2 different strakes?
