      It is a turboprop (ish) - the ‘groundbreaking innovation’ they’re testing is the hybrid electric/heat recovery architecture, which if it pans out could indeed be a huge advancement.

      The novel engine design, which is known as SWITCH (Sustainable Water Injecting Turbofan Comprising Hybrid-Electrics), will look to demonstrate the hybrid-electric and heat-recovery turbofan technologies, with a bid to lower fuel consumption by 25%.

      I would have to do the math, but I would be shocked if a cowling actually caught a blade failure. There is a lot of energy involved and the cowlings are thin to keep them light.

        Haven’t they been adding a kevlar liner to the inner section of the cowling for a while now for that exact purpose? There was a pretty crazy incident a couple of years back where the liner came loose and got trapped in the intake blades. I was under the impression that most non regional jets were set up like that.

    I hate to state the obvious, but isn’t that just a propeller?

      It’s all a variation on the theme of propellers: a high-bypass engine is basically a ducted fan, which is nothing more than a propeller encased in a shroud at the end of the day.

      It is, all engines have them (well most, there is experimental propless one), just that in most modern combustion engines they are encased. The revolution comes from the blade design, the counter rotating fans design which needs such precise calculations to work efficiently, that supercomputers are required and then there are new composite materials among other more incremental advancements. All of that will allow them to design blade-out modern engine which will have radical improvement to efficiency.
