    Best quote from How a Turbine Engine Fan Works: Jet Propulsion Explained

    “

    The fan blades are moving so fast that they essentially act like a rubber skin; as soon as a gap opens up, the next blade arrives to cover it, maintaining a permanent wall of movement that prevents high-pressure air from escaping.
