Thread: Milviz F-15E Service Pack

  1. #401
    We are now in the midst of remaking and fixing a lot of stuff for the Eagle E. This does, sadly, take time. But, that said, we will be releasing a second iteration of the SP1.1 beta shortly. This will fix the installation issues at the very least and a lot of other things as well.

    Just purchased the MilViz bird and the detail and systems are very nice indeed.

    The customer support is also first class.

    Cheers.

    Yes, the Iris F-15E has this effect.

    For me, It's clearly audible from the front and back seats, "Flyby" mode, and from "Landing Gear View", looking forward.

    It cannot be heard from "Spot View". I'll mention it to Tim on the bugs page. It's likely they intended it to be heard from "spot view".

    Hopes this helps.

    Sure does, but what's the deal with discussing Iris' plane in the Milviz thread? If I may, I suggest that we move to this thread to discuss the pros and cons of either: http://www.sim-outhouse.com/sohforum...E-or-IRIS-F-15.

    oops... my bad, it's a long thread. Just answering a question a few entries back.

    For the record, I purchased the Milviz F-15E and really enjoyed their product with the beta service pack. I've parked it until their final service pack is released.

    Milviz has been excellent customer service-wise for me and I will be buying their charlie model when its here.

    Congrats and thanks for following through with your E model.

    Ahh those videos are perfect, I thought the sound came from an aux blow in door or something, the vids clearly show the sound is the nozzle servo motor running. To be honest the sound I've heard is more harsh and much shorter and sharper, less than a second usually but could be the same source.

    Kindest Michael

    I thought i would have a go at a repaint but decided that there were too many psds to work with (9!) and I could not get them to work properly in photo shop.

    Such a pity

    Well yes the paint kit for the «E» is extremely complex. I have tried to simplify it as far as I could. But there are a lot of details to be applied, so the complex kit is required.
    If you'll be kind to send a PM, I will try to figure out your problems and help solving them.

    I quote from other websites explaining the sound-----

    Yes; what you hear is the CENC "Convergent Exhaust Nozzle Control" that moves the actuators for the engine's exhaust nozzle.

    If it 'zip-zips' (whistles) when the throttle is moved it is a F100-PW-2XX. The F110-GE-1xx engines use hydraulic (engine oil) actuators to move their nozzle, which is silent.


    The CENC uses high-pressure air from the 13th stage of compression, the highest in the engine, to move the nozzle. The CENC is akin to an "air-motor" As the air moves through the CENC in one direction the nozzle is "driven" open by flexible-shafts that turn screw-jack type actuators. In less than a second, the CENC can turn 341 revolutions to fully open or close the nozzle. When air is directed through the CENC the opposite direction, the nozzle will close as everything spins in reverse.


    The CENC controls "nozzle position" or Aj (Area Jet) which is the primary method of maintaining proper EPR (Engine Pressure Ratio) and N1 (Fan RPM) Whenever the pilot moves the throttle, or PLA (Power Lever Angle) the engine adjusts for the requested thrust, and Aj is the most evident adjustment made. (Nozzle opens/closes and the zip of the CENC is heard)


    The CENC has an exhaust port that dumps the used air overboard. It is located about 5 o'clock on the engine just aft of the 'H-Flange' where the augmentor duct attaches to the aft-fan duct. On the Viper the exhaust port would be located between the ventrals, more towards the one on the right.


    Every PW F100 engine has used a CENC to drive it's nozzle. Even the prototype F100-PW-100 made this sound. Some rumors say that this sound is the "screech" that gave the F-15 the name "Eagle"
    --------------------------------------------------------
    One is the PW nozzle showing the Speed Break open. The "Turkey Feathers" are the External Nozzle Segments. The parts that run horizontal around the nozzle and say "NO PUSH" at the aft end and "NO STEP" at the forward end. The newest PW-229 engines have black carbon-fiber Turkey Feathers.

    The sound in the videos posted above reminds me of the leading edge mechanisms of a Boeing 747 which aren't exactly similiar, of course. But the noise of the mechanism is a screech-whirr at high pitch and very very loud. If you stand under the wing of a parked 747 when the leading edge is extended you can watch the "flexible-shafts that turn screw-jack type actuators" turning. Not that the comparison is perfect. But the sound will make you jump out of your denim jeans ----if it is new to you and you have no ear protection.

    A Chinese girl I once knew, helping her learn English, described denim jeans as cow trousers. Love that girl, miss her.

    Where was I? Oh yup, that noise should be added to aircraft such as the F-16 but how? Proper engine of course.

    Once again your knowledge and research enlightens me, being an engineer I find this sort of information interesting and enhances my enjoyment of aircraft.

    Thank you kind sir.

    Uh, exactly this sort of thing happens all the time in the SOH forums and quite often with Milviz stuff being discussed on other's product discussion threads. So, yea, but no harm no foul.

    Have to agree. Always interesting to hear about the inner workings. Thanks for sharing.

    Thanks Frank Safranek and Michael Davies, owe you ales, I mean a barrel.

    Now then, how do we put that sound into other aircraft, anyone? I've never tried. It's a new thought to me but I'm researching it.
    I 'll guess there are folks that do know the procedure.

    I don't think the pilot in the cockpit would hear the sound in a real aircraft. Or not much. But outside would be different.

    What’s the current situation regarding the Service pack for the F-15? I have installed the beta when it was first released, so is there any point in installing servicepack 1.1B? And is that the finished item?<o></o>
    This topic seems to be slipping of the radar.<o></o>
