Aircraft Streamlining: Benefits and Drawbacks

[Normandxavier]

Is it good if an aircraft has lot of streamlines ?

Welcome to PF!

The way you are using that word isn't correct, so my guess is you are thinking something else. Any object moving in air (or air moving around an object) has a near infinite number of streamlines.

So did you mean something else?

Any object moving in air (or air moving around an object) has a[n] near infinite number of streamlines.

Fixed that for you.

Fixed that for you.

Ya know, I actually said that first and then changed it. I thought someone might start an argument about the (im)possibility of streamlines smaller than a molecule of air.

Thx for your reply . I appriceate that

 

[Normandxavier]

Well basiclly i don't know much about streamlines

I already read about streamlines, so why an aircraft traveling at supersonic speeds requires a different streamlined form from a subsonic aircraft ?

Perhaps the simplest answer is that flow moving at supersonic speeds behaves quite a bit differently than that at subsonic speeds.
