    Default SKULD 666 Turbine

    OK time to start up this build thread on this engine build, this engine will be a monster and will be the biggest home built turbine engine in the world. Mr John Wallis has work on this engine on and off for a number of years, he ask me if i would like to finish of the build no worries i said. So here a bit of info of the engine and photos. John stated the build back in 2013.

    .. the SKULD 666

    A mixture of Nordic mythology and the occult ................

    comprising a mans destiny ,

    a 6.66 inch diameter "hole in the front",

    and 6.66 lbs/sec mass flow .

    Compressor wheel is a titanium billet first stage wheel from a Garrett TPE331 aero turboprop engine .............exducer diameter 9.2 inches with a 0.5 inch tip height , spinning at ~42,000 rpm with a 1,700 ft/sec tip speed for a 4:1 Pressure Ratio .

    Turbine wheel is the axial second stage turb wheel of ~8.4 inch diameter.

    Engine casing will be 14 inches OD with the engine overall length of ~18 inches .

    The Garrett TPE331 parts are cheap to buy so got some spares parts that we will need for the engine build. I sent the NGV and turbine wheel up to John so he could do some calculations and machine the turbine wheel.

    Machine up a dummy shaft, had to work out the speeds and feed rate to get rid of the vibration. Going to use ball bearings instead of journal bearings, the ball bearings will ceramic ball bearings, got a couple of cheap angular contact bearings for test fit will have to grind the inner race a bit so i can fit the ceramic balls in.

    Ha ha!! looks like that will be me I have some heating oil that i can use these things can run on just about any type of fuel. This engine will have a different type of fuel delivery system, it won't have vaporizer tubes like the micro turbines use. I'll be using small spray nozzles that will spray the fuel down the flame tube about 18 nozzles i think.

    The fuel won't cost that much guys . John Wallis use a diesel petrol mix in his engine works very well cheaper that kerosene. This thing will be very loud, so will test run in the industrial area, EnZed in Bayswater said i can do a test run with the Skuld and the JU-1 so that will be grate as not to far from were i live. Johns 12/118 engine is loud to https://www.youtube.com/watch?v=J29zgn7xv6g&t=43s Just after this run a chap pulled up in his car and was chatting with John about his engine and said he can hear it at his place which is about 3 KMs away
