What is Spiral Engine?
The spiral is a prominent visual cue that accentuates the rotating motion of a jet engine’s front air intake fan, so airport ground staff can easily identify a running engine at a glance.
An active engine can ingest objects and humans in close proximity, causing damage and fatal injuries. Therefore, a rapidly rotating spiral serves as a clear warning for people nearby to stay clear from the engine.
the spiral marking makes the running engine look significantly more obvious. This is especially vital during nighttime operations, as the spinning fan blades are difficult to see in low light conditions.
The airport workers can also deduce the approximate power setting of the jet engine based on how blurry the spiral appears to be, and determine when it’s safe to approach the engine.
While the spiral pattern is ubiquitous nowadays, it isn’t the only design used by airlines. In fact, there are quite a number of variations, depending on the engine manufacturer, and they’re all designed to be very eye-catching when rotating at lower speeds.
The spiral’s main objective is to warn airport ground workers to keep clear of a running jet engine to avoid the risk of being ingested into the engine.
