Actually Bill I saw a few sets of conrods that would suit that at Erzhong in my city a few weeks ago, I wonder if they get them made here.

Have a look around Erzhongs website, it's the the biggest general engineering works in the world .. http://www.china-erzhong.com/erzhong-en/dy/ShowArticle.asp?ArticleID=887

If you go to 'Facility Capability', 'Forging Capability' and have a look at the 2nd small 3D picture of an 800MN press, I can tell you it's very real and I have stood in front of it with my jaw on the ground, it's indescribably massive. It's soon to be commissioned and Rolls Royce are waiting for it to press turbine housings and other parts for their next generation ginormous jet engine that can't be made until this particular press is finished.

Ok ya big sook ...

and the best for last ...

I came across this bunch of birdstrike pictures recently, don't click on the link if you don't like blood ....

(see images in 4th post below - Admin)

I need to mention that it will probably be a very slow load for some of you, as in go make a coffee slow.

Any chance there will be a diesel variant an some time?

you are set to become the willy wonka of aviation engines?

Ozzie, stuff a piece of steel into a meter or so of garden or fuel hose, put to your ear and start touching the steel around the engine finding exactly where the noise is coming from.

Very dangerous of course, don't concentrate so much that you and the prop connect and that's why the hose rather than a screwdriver, so you can keep some distance.

Electric motor ARE very scalable.

The problem with all these wacky aviation engines, by the time you pay for the custom exhaust, mount, radiators to be fabricated and your engine installed you haven't saved any money over buying a 912s. And then you come to the problem of keeping it flying when there are no parts in the country.If you want your engine to succeed you need a high degree of FWF compatibility with the 912s.

All parts are already available over the counter and have been for the last 20 years at a 1/10 the price of Jab or Rotax etc, parts.

I don't see how you justify your "wacky" or "parts availability" comments at all without knowing a single thing about the engine or it's concept foundation

If you can't mount the engine and (supplied) radiator for the $10,000 difference to the Rotax then I have a bridge to sell you anyway, I mentioned it will use Jab engine mounts so that certainly lessens the burden as there's a few off the shelf mounts already available for the Jab for various planes.

The exhaust if by far easier to fabricate than any Jab, Rotax etc., and I'll repeat, it would be advisable to wait for concept info before making comments.

Oh all right here's a sneak preview ..

Old Jan is really taking the bull by the horns now supplying engines at crazy prices..$12,000

No experience but I know some of them run a slipper clutch and slipper clutches can get pretty noisy so Google that maybe?

Hmm I just Googled it and got a few examples such as this one ...

Im not sure what you mean Alan ? To date, I have OVER 3000 hours of electric flying time with RC aircraft. Never had one issue ! Electric engines are very proven. Have been for over 30 years ! I would MUCH prefer to be flying an electric than an old 337...447...With respect, have you ANY evidence of even 1 in flight failure of an electric engine ?? If so, it would really help with with my research so thanks if you can ? we have not been able to find even one to date...

 

Thanks for your input Alan.

The electric car company I work with sometimes, have had multiple failures of controllers, battery cells, terminals etc. and there's no way you would get me into a flying version. They use some pretty good quality stuff too as well turning out 2 or 3 vehicles per week.

Engines themselves rarely stop if ever but that's only a small part of it.

As for hybrid, well it semed nice 15 years ago but turbo diesels are flying past them now, go compare a VW Polo Diesel with a Toyota Prius, the Polo wins in every way hands down such has been the advances in diesel engines in the last 10 years.

PS; Why do all electric planes have to look like sci fi magazine cover pictures?

No idea what the reliability fears are all about - so many less moving parts and such simpler operation...

If you could get a good Rotax 912-equivalent out in the next 5 years, I'd appreciate it... might finish the airframe by then...

Looking at 2 models currently to develop (in modular form), 80 to 90hp and 110 to 120hp. Of course I am going after Rotax's market segment but with some very interesting and logical (for airframe anyway) layouts including a beautifly simply answer to reduction drive.

Also all major parts are of mass produced OEM origin, maintenance and servicing costs will be of a level not seen before in the aero industry.

I am frustrated I can't tell you more but as with IPR any pre-public disclosure immediately nullifies your claim, that's the law.

have you noticed that most new aero engines are designed for airframes that don't exist?

Our first airframe (Oz) exists currently and is flying. Other models on drawing board and knowing the Oz designer (in time) will offer nothing less than complete confidence.

My engine and airframe are seperate entities, not even the same company.

I logically expect to move many multiples of engines relative to airframes.

I will be using Jabiru mounts, no reason to make unique there.

they wiped our bloody backup disk

Thanks for your efforts Admin, it's appreciated.

PS Bexrbetter is doing something we have all been hoping for, ie to provide an affordable and reliable aero engine for our projects. He certainly has my encouragement because if he is successful, it is for the benefit of many. Go Bex!

Thank you for your kind words and you will hear the full story soon enough which is quite favorable to Australia. I have tried very hard to keep everything about this project Australian experiencing some very frustrating levels while doing so especially when I have Americans and Euros knocking on my door.

I do have 3 Daughters and 3 Granddaughters living in Oz and I do care about their futures.

By the way, for your cooling shrouds, I suggest you might try decreasing the mouth opening size and test which way the temps go, sometimes if the opening is too big you can actually get flow stagnation or even reversal - just something to try, it may be worse.

maybe make a better cooling fence than the supplied fiberglass ones.

Aldo, as requested by Admin I won't pursue this any further even though addressing your contradictions would be amusing, but anyway.

I will answer one question, I have been living here for 10 years mostly in the design and manufacturing of machinery. My wife is one of China's leading lawyers, owns her own law firm and is a Partner in one of China's top ten. I have insights not even available to most Chinese let alone Foreigners.

My products do the talking for me and of course that will be in this arena soon enough to be judged, in the meantime enjoy all those Chinese parts inside your Jab engine.

Sounds like more un common sense

Marty, was just considering that yesterday!

My thinking was generator brakes, spin 'em up then slow you down.

Alternately why not just knobby tyres with spats so the drag on the exposed knobs keeps the wheels spinning permanently.

The Chinese industrial are masters at copying and I can see them being a major force in manufacturing, and producing quality goods in the near future. '

I am today assembling an outdoor 2 person swingseat and it's great quality except they didn't include assembly instructions and the tool kit consists of one spanner - all of the bolts have nyloc nuts, try doing them up with just one spanner .... It's that annoying idiotic small stuff they have to get right.

The best way to get a quality australian motor in your plane is to support the newer manufacturers like ....

Thanks for the plug Mate.

I knew somebody who did that, he was a strong headed risk taker, as a result he is now quite 'armless'. Alan.

Thanks for the update Kevin.

I have no doubt that China will a dominant force in automotive and high tech manufacture in the near future. You only have to look where the Japanese were in the mid 50s and China has one hell of a head start compared to the Japan situation.

Simply put, there's too much low level graft and too many components suppliers to control so something will always slip through the net. Of course they will sell well simply due to price.

When I first arrived here I noticed in my many visits to Companies that the Purchasing Officer often drove a car while other workers were on motorbikes or bicycles, what does that tell you ...

More people die in Fords than Robbies why don't we have them all taken off the road too?

Because buddy, when a ford rear ends a Holden in a 40 zone, nobody gets incinerated. .

Very bad analogy ..
