    Dynamic Prop balancing

    in Engines and Props

    Posted

    Finally made the bracket to fit the balancer and tried it today, started with .08 ips out of balance which according to the book is not bad, but I had a play and got it down to .02 ips, great to use and easy once you have worked out how much weight and where to put it.

    hi lindajust looked and seen your at baccus marsh im in qld but go to melbourne 3or 4 times a yeqar maybe come and have a sit in then?

    cheers gareth

    Gareth,

     

    It would be great to catch up on one of your trips down to Melbourne, we come up to Qld quite a bit as the family live in Bundaberg.

     

    What part of Qld do you live in?

    Hi Linda,I have been planning to visit Baccus Marsh and Ballarat.

    Did you and Brian build the j160, or was it purchased assembled?

    We built the 160 over a period of about 3 years...give or take. She sort of sat idle for about 8 months at one time due to work commitments.

     

    I Keep my Jabiru close to me at Riddles Creek Airfield YRID.I have had my Jabiru about ten months,engine has about 140 hours on it.

    In this time i still can not work out how much oil to put in.

    JWW. Keep it near the low mark and it should be fine.

     

    If you are ever coming over this way, give us a yell. I will pm you a phone number you can contact us on.

    I own and fly a Jabiru J160 and live in north west suburbs of Melbourne.

    Have been flying for nearly three years and learnt to fly in the friendly crosswinds at Tooradin Vic.

    Welcome JWW!

     

    What part of NW Melbourne do you live in and where do you hangar your plane?

    Gareth,

     

    We have a J160 and we find that the 160/170 have more cabin space than the 2oo series.

     

    We try and encourage people to come out and have a look and sit in the aircraft to get a better prospective of what these aircraft are like.

    Sounds good jetjr, yes the balancer looks to be easy to use and the more you use it the easier it will become to know how much weight to put on, I just think that the smoother things can run the better it has to be on the whole engine and airframe. I have spoken to someone who also has one of these balancers and they have sent me pictures of the way in which the balancer was fitted to their engine so I am in the process of making the mounting brackets to suit what I need.

    Bruce,

     

    At the moment I am just looking at temp spread over the whole engine as I haven't fitted it to an aircraft with internal probes to compare it against, the exhaust senders just clamp onto the pipes and give a reading of pipe temp, but you can still see a variation on cylinders if they are running rich or lean, It's a compromise that allows you to get information without altering anything on what you are checking.

    Hi Bruce,

     

    I have 6 EGT and CHT thermocouplers that get fitted under the sparkplugs and clamp to the exhaust which the cable then comes into the cockpit and connects to a MGL TC3 reader, it gives you the ability to use 1 to 12 termocouple senders and gives a live reading much the same as a Dynon and when you come back and shut down you can get the hottest temps that each thermocouple has reached as it is stored in memory until you clear it. Everything fits into a box about the size of a fishing tackle box and can be fitted and removed once you are happy with whatever you are trying to solve, whether it is to check the senders or guages that are in the plane or trying to get more even cooling through air ducts without mounting permanent senders.

    Not yet Vev,

     

    work has got in the way at the moment, but I will get to it soon as I want to see the difference that it makes to our plane, hope it is as good as I am expecting.

     

    I have just finished setting up a portable EGT and CHT reader that can be fitted to most engines without having to drill holes into the exhaust to fit probes for diagnosis work, once all the thermo couple senders are fitted and the wiring is routed into the cabin, you can then go flying and watch a live reading to compare all cylinders at all rev ranges, when you come back you can then see the hottest temp each cylinder reached and then make a decision on what to do to achieve the result that you require.

    Rolled Thread Engine Through Bolts Available as alternative

    Ok so you can quote 5 engines all with different faults, big deal.

     

    Check out the latest Flight safety magazine and see how many continental and other engines that have failed, some are low hour engines and some have lots of hours on them, and they would have recources that would be second to none. We are talking about a mechanical piece of machinery that does and will have failures, doesn't matter who makes it.

     

    If someone thinks they can make a better product than Jabiru then they should go ahead and do it, but don't go bitching about a product that has some failures unless you can come up with the answer to fixing them.

     

    If you don't like the product no one is forcing you to purchase it.

    Jabiru engines are a great engine when they are treated right, the faults that are happening are reasonably easy to fix, the problem is the certification system that is in place which prevents people from straying to far from the standard engine design, even when a better way is found to improve the overall design. These engines can acheive very good temps at cruise, EGT's that are within 20 deg C over all cylinders and CHT's that are about the same with a few tweeks, all without liquid cooled heads and fuel injection. You don't need to over complicate things by adding so called fixes when you can build the engine to achieve the desired results. The best thing about a Jabiru engine is the simplicity in the design and the cost of parts. Which is something that if it did not exist would prevent a lot of people from flying.

    Any damage Ian?

     

    We had large hail here and there were a few of the flying schools and the aircraft that the LAME was working on that were outside have had substantial damage done to them.

     

    We suffered a broken laserlite sheet in the hangar ceiling and several dents in the door and roof, but no damage to our plane.

    I'm going to be in Gympie for the next couple weeks fleet servicing for a company there. Hopefully I'll find some time to head over to the airfield and do some flying! Look out for me! prop.gif.61637aee349faef03caaa77c2d86cf41.gif

    Time to do some video aswell ? Gympie is fantastic from the air. 020_yes.gif.58d361886eb042a872e78a875908e414.gif
