It's patented: The positions of the slots are such that the high velocity air exits the slots tangential to the outer surface of the cylinders. Due to the Coanda effect, the high velocity air follows the contour of the cylinders. In the case of the inboard nozzle, the high velocity air impinges on the exhaust gas stream, deflecting it outboard away from the aircraft fuselage. In the case of the outboard nozzle, the flow of the high velocity air along the nozzle's cylinder creates a low pressure area adjacent to the cylinder which draws the exhaust gas stream toward the outboard side of the exhaust duct. The combined effects of the two nozzles result in significant deflection of the exhaust gas stream outboard away from the aircraft fuselage. Hah!

This is funny. OK, Herr Rot, you have more stories like this, to scare the bejeezus out of me?
TECS!! Your pills!
Funny. But hey, how come you didn't comment on my Coanda pic? Did you notice the Coanda effect on the jet fans?
I didn't notice. How can you see that? Do you need pills or a cellphone?
You need a magnifying glass, Herr Rott. And a better knowledge of the No Kant Do effect.
That plane has bedding stuffed up its exhaust. What effect is that?
Perhaps it's called the toamponda effect?

Of course, me personally, I prefer having the pedal to the metal than the exhaust deflected. De gustibus non est disputandum.
