    This boat is powered by a nonafterburning Rolls-Royce Spey turbofan.

    A British 4,900 ton Type 22 frigate capable of thirty knots uses two Speys to power its turbines.

    I'm wandering what'll happen if a minimum wave enters that big low mouth....:confused:

    I don't think that they would go out in waves bigger than a inch high

    Water ingestion

    Well, although waves will never be an issue water ingestion still could be depending on throttle setting (and resulting suction) and forward speed.

    Bluebird

    At various times in its career, water ingestion was an issue even on Bluebird.

    mmm, we will have to see where they are running the trials and see what happens, if they use Coniston Water it is only 5 hours from where I live so I will pop up and have a look

    I guess then that some water ingestion is acceptable, I guess that something that is designed to shred a pigeon and survive could handle a bit of water

    reminds me i'm still waiting (but over a year now:rolleyes:) on some water injected turbine papers
    didnt you wonder about thrust flying / landing in poorin rain or what is the expression for wet wet wet

    Water

    Obviously, whether operating from land or water jets have to tolerate some degree of water ingestion.

    On modern high bypass turbofan engines water ingestion is not much of an issue. Due to the centrifugal forces when the water hits the big fan at the front most of it is thrown to the outside and never enters the hot engine core. This one looks like an old sucker though. No idea why they don't use a bypass engine. Pure jets are only required if you want to move at the speed of sound or faster and I'm not sure if they want to go that fast. It's probably for engine cost reasons.
