BF2S Forums Why do airplanes have those little swirls on the center of the turbine

ive seen em on props before, so blah.

They serve to hypnotize you before they suck you in and tear apart all your flesh and bones.

It's so you don't feel anything.  It's real nice of them to do that for you.

If you see a full circle, get out of the way.

That is the funkiest looking jet I have ever seen.  Wiki?

I sincerely hope you are kidding.

It's probably a Photoshop Phriday or something, but it is certainly a photo edit.  That is NOT a real aircraft.

It totally looks photoshopped.

These real turbines don't have spiny lines on them.

I imagine it's there to let you know when the turbines are spinning. Sometimes it can be difficult to tell, especially if other planes nearby are creating a lot of noise and you can't tell what sounds are coming from where.

I'm not entirely sure, though.

Gimme a reason why NOT to put em there, they look cool, they tell you if/where the blades are turning, they keep a web forum alive with discussion.

It's to tell you they're turning, well, for deaf people anyways.

The Turbine "Spiral Logo" is a legal Occupational Health and Safety feature installed on most (if not all - where applicable) aircraft liners and turbine engines (whether commerical or private). It's as pointed out above, to determine if (and how fast) the turbine engine is spinning so ground control can perform their tasks safely. Back in the day there were accidents because Ground Personnel couldn't tell if a turbine was moving when it was at full speed and on ground level you canont tell engine noises apart. They also paint lines on propeller aircraft (back and front) and also helicopter rotors that can be seen from any direction for the same reason.

And yes, people have survived being sucked into those engines.

That, and even when the turbines aren't spinning, they still create a fuck load of noise themselves. It isn't just other aircraft that make it confusing.

wtf are you talking about that looks like a normal plane
