    Dear friends and followers, welcome back to my channel, clarifying another great question. Why is there a spiral or swirl in a jet engine?
    The primary reason for painting designs on engine spinners is for the safety of ground personnel. Working near a running jet engine is extremely dangerous. For example, a Boeing 737 engine, running at idle power, has a hazard zone of 9 feet to the front and sides of the engine. This means that, even at idle thrust, a human that walks within the hazard area or any loose objects, risk being sucked up into the engine. When the engine is above idle thrust, the hazard zone increases to 14 feet or more. Not to speak of the even larger hazard zones of a B777 for example. Therefore it´s absolutely critical that ground personnel can identify a running engine and stay away from it.
    Even though jet engines are incredibly loud, a running engine may not be obvious to ground personnel. Airport aprons often have several aeroplanes in close proximity with engines screaming next to each other. Therefore ground personnel have to wear hearing protection to suppress the deafening noise. Making matters worse, it can be hard to see that an engine is running, especially during night-time operation, as the black and grey fan blades become translucent when they´re spinning.
    Therefore spinning spirals make it a lot easier to identify a running engine. Besides that, ground personnel can check if the aeroplanes´ red anti-collision light is still flashing. This indicates that pilots have received their start-up clearance and will start the engines very soon. On arrival at the gate, the light is turned off by the pilots after the engines are shut off and „spiral“ down, after which it is safe to approach the engines from either side.
    For the same safety reason, the tips of propeller blades on propeller-driven aeroplanes like the Dash Q400 are painted in bright colours, to be more visible to the human eye. You won´t believe how many incidents have happened in the past involving jet engines and ground personnel.
    Do they scare away birds? That and more information in the video!
    Thanks for watching, all the best your "Captain" Joe

    In the US, “Apostrophe” is pronounced “a-POS-tro-fee”.
    Aside from that, great video!
    I’m sure there are many German words that Americans who speak German might mispronounce. Like “Mar-LAY-na” Dietrich pronounced “Mar-LEEN.”

    Captain Joe $40 not 40$.


    ok if birds are attracted to the blackhole seeing the engine inlet as a dark cave. Why not paint the fan blades white along with the spinner cap, the bird would see a white object and not a cave and decide to avoid it instead of flying into it


      +Rick Traveler Smith thats easy paint them properly lol they are painted at the factory anyway soooo this concern is redundant

    I think that also some sort of stroboscopic effect at nights caused by illumination lights may "freeze" fan blades to the eyes of a ground service worker. Spiral in this case indeed remains visible.

      They acctually used to do it but I don't know why exactly they stopped doing it. My guess would be that the pilots can't see anything behind them when reversethrusting themselves backwards potentialy putting lots of people into danger.

    For long time I thought the main function of the spiral . Is when the engine is switched on. The ground engineer is needed to examine the engine by looking at the spirals and give the okay to the pilot

    In auto racing we called the markings op chalk. I don't think they have differing names around circuits. Just operational chalk (op chalk is almost always a paint, wax or chalk) and is the mark on the gear or wheel For example; if the chief wanted to know if a cam, or piston was TDC (top dead center) he would say to his Apprentice to check the op chalk on the cam gear
