Remarkable explanation, I knew why they're found on engine nacelles but I learned about a few other places that they may be located.

[@AndreaSSLeventiSS]

nice video! a bit detailed explanation: It increases the vertical (downward) component of the airspeed thus ''sticking'' to the surface

Can anyone tell what is the thing that attached to the wing end?

[@tinuvarun5806]

Winglets or sharlets, it is there to reduce the drag caused from high pressure air in lower surface meeting low pressure air in the upper surface.

Is Nacelle a engine cover?

[@JxJAVIATION]

Yes it is!

[@thortt515]

Are these things the so-called vortex generator?

[@JxJAVIATION]

Their function is same as vortex generators but these are called as strakes!

[@Jutte777]

The F18 - a bit simplistic there buddy .They do a way lot more than that...

[@JxJAVIATION]

This was just a basic explanation
