    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

At first, the question about the use of that spiral seemed to me too obvious to be asked. But Captain Joe is teaching us several additionnal interestings facts about aircrafts. But one question remains to me: why isn't there a safety metal grid in front of the engine air entrance so that a ground worker or a bird would no be sucked into the turbine fan?

Why don't the engine makers put a grid on the front of the engine to keep the birds out?

+h8GWBî 1) That depends on the size of the openings. If the openings are small enough for air to pass but not bird, the amount of bird getting to the turbine blades will be very small. 2) To minimize FOD, it could be integrated into the engine front shroud, either as a permanent fixture or as a retractable deterrent.

Bc at airplane speeds a bird would still enter the engine, but in more pieces. Not to mention the constant FOD threat from any failure of the grid.

Y don't they put a cage in front of the engine, in case a bird does fly towards it or a person gets sucked in the cage will stop them

Cuz you need perfect air flow to get the best performance of the turbine, also if something hit the cage and it brakes the intire engine is wasted into one beautifull explosion.

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.”
