An engineer will usually choose materials based on the application and design, and may well choose two suitable materials which will give years of use without any lubricant. In those cases separating the hinge parts at intervals, washing with water and blowing any dirt/dust particles out ensures a long life.

Or for another application, he/she may choose different materials such as steel and bronze to prevent lock up, and specify grease nipples.

In other cases oil bath or oil splash might be used.

I would be going to the manufacturer of the hinge for that specific model of that specific aircraft rather than relying on a generalised opinion on a public forum.

What you've read abive should put enough fear into you to be very careful what you do to an airleron hinge.

Turbo had been hoping the story wouldn't have to come out, but it ssems it must.

Not many people know that Captain's Great Grandfather, Colonel Blimp was the Chairman of the Ponce Cricket Club, which in its day rivalled the Marleybone Cricket Club in it's stickling to rules (in fact Ponce is where the word "stickler" comes from).

The Ponce Club was the centre of activity for the British expat contingent from lunch time onward and many of them were players in other things beside cricket, particularly the good Colonel Blimp. The members would bet each day to see whether he would get caught and at what stage. At mid off, he could often make his escape and no one would find out about it, but at mid on he was like a deer in the spotlights, and it was Lt Col Algernon Lacey that said "Either way he's silly" and the names Silly Mid Off and Silly Mid On quickly found their way into the Ponce Cricket Rules, and they were adopted during the 1871 cricket tour by the Marleybone Cricket Club.

It was Algernon who said "We have to do something; although Blimp is wicked, sooner or later someone is going to challenge him to a duel, so an orderly was paid to fill him up with gin each afternoon, and that became known as Wicked Duty. That also quickly passed across to the cricket field, although the drink name coined by the Australian Team was Crocodile Juice, which a couple of centuries later became Gatorade.

Thank you very much Turbs great information and very helpful. Your time spent for researching is much appreciated I never realised the depth of this. Andy

What I like about it is that it's clear and concise, and doesn't contain the last 60 years of versions we are no longer supposed to be using.

Yep I would be for that.

Correct me if i am wrong but today in NZ is 75 days FREE of any cases. All back to normal for them except international travel.

There's not a lot of point talking about the situation we had in Wave 1.

Today we are dealing with community transmission, where, for example a lawful truck driver can transmit the virus two states away.

[For lack of a conjunction the NES had come to a complete halt. Posters couldn't write anything, and the fickle public abandoned the site like blowflies off a Kudu, and Een started to ask if it was Covid, so although Turbo rarely explains simple English because his posts would quickly outnumber Dazza's wonderful spelling assistance (which just wasn't appreciated by those who needed it most) he advises that he did indeed mean Wicked Duty.

It's a sad testament to today's youth that even though cricket is still played, no one knows what Wicked Duty is.]

I have reached the conclusion that, in Australia, we are simply attempting to ensure that we do not overwhelm our Health Services at any stage and it will simmer-on like this for many months, if not years.

The Health departments haven't been telegraphing their strategies, but I think Health Service Capacity is one of the biggest trenches they will defend, because the Victorian Premier opened up on this a couple of days ago explaining Victoria's total lock down of the towers when he said something like "when we start filing our hospitals we will reach capacity very quickly and once we do that you will see mass deaths, because we don't have the capacity to treat anyone, so we don't want to get to that point where the front line is our hospital capacity; we want to avoid that at any cost. You'd realise what that means to people out in the country - a nothing we can do fir you in the cities messages. From what I saw during the Wave 1 lock down, country people were transferred ti incubators located in the cities by RFDS, and on at least one day RFDS was reported at full capacity doing transfers.

So we have this massive team made up of people not only from Victoria, but from the other States as well working to interview and trace thousands of people who have been contacted by positive cases. If Victoria can clean up its current outbreaks that team will move seamlessly to any State in need, all to prevent hospical capacity determining our limit to reducing the virus.

You can see from the graph I posted early that active numbers in Victoria have reduced for four days, and also giving us heart is the fact that the big numbers from the Towers, Al Taqua school, Hume should all be in those numbers, but you can also see from the cum line that we can't be comfortably sure.

However, it looks as if this is a good way to fight the virus outbreaks - like a bushfire; get in fast, hit it hard, try to knock it right out. The backburning is those cellular lock downs.

If that goes on for five or ten years, and there's still no virus then that's where we're headed.

However, my personal experience of the SARS epidemic gives me hope that it may just fizzle out at some stage.

It does seem to die quickly, once the people in an active cell are isolated and measures are taken to elminate the spread.

In Keysborough, Victoria, at a duck farm in the 1970s Avian Influenza broke out among the ducks and had the potential to wipe out a lot of people in the local area, more if it got into the wild duck population. The Department of Health ordered the ducks to be destroyed, and a million ducks are buried in this City suburb. This history was given as a reason not to build around 10,000 houses over the top of them, and I finished up dealing with the Head of WHO for the Pacific who was based in Hawaii. He was very impressive, asking for all the details, talking to a couple of scientists, and coming back with the decision that given the size of the kill, location etc. most of the virus would have died in the first week, but they were agreed that no virus would be living after six weeks. Since this was several years later they said that the site would be inert so people could dig foundations, gardens, etc and there would be no threat.

This DHHS graph for Victoria shows the fourth day of reducing CV cases at 238.

Not quite wot I was thinking...

Fairyland really does exist.

Do these people have an affliction that makes them vulnerable ? ( this is the thing I hate, If someone is in good health and Covid takes their life it is a tragedy. If you are in a position where any infection could do the same thing ............why blame Covit 19, it would have probably happened from the common flu !

The common flue could compromise their health....... many died last flu season from complications .

These are people being treated for Covid-19 infection and were included in the afternoon report.

The last I heard about the flu was that our social distancing and hand sanitising had dropped it to 1% of last year, so there's a good chance next time we look like having a bad year that will be the way we go. Definitely lives saved.

You don't fly recflying to get to places . You do it because you like flying and aeroplanes and use going somewhere as an excuse. Nev

Interesting that a lot of people who have had problems were flying places as if they were using cross-country aircraft.

These are the ages for the confirmed cases in Victoria. Back in Feb/March it was thought the over 80's were the most at risk but deaths are occurring where people have low immune systems, so the young can die.

From memory two or three currently on ventilators tonight are in their 40s

For those talking about jobs, finance, the economy, the CHO said this afternoon said he's not ruling taking us to Stage 4 lockdown; that would focus a few people on the problem.

.....fly an aircraft by memorising all the rules of cricket, then allocating an action to each rule and.......

I've always considered the OTTO cycle was the usual 4 stroke concept.

Apparently with a spark plug and Diesel cycle without the spark plug.

Couldn't agree more. We have "flattened the curve".

That was for Wave 1. In fact we flattened it beyond our wildest dreams.

So lock down was removed and our population let loose, partying, filling shopping centres, overflowing out of pubs and restaurants etc.

For the various reasons there was a second series of outbreaks which has developed into another bell curve - wave 2, and as of this afternoon that has been flattening over the past three days.

The healthcare system is prepared to cope with the infections we're likely to encounter.

this time around Victoria has several million masks, hundreds of ventilations, a $30 million upgrade completed of the Peter McCallum Hospital which is ready to go for ICU cases, thousands of front line workers ready to go, and the experience of what worked in Wave 1.

HOWEVER: We don't know what we will face, who will behave, and who will ignore the proven safe path, and we could still be out of ventilators in a couple of days and start seeing a horrific toll. The effort put in by a massive team of tracers has so far allowed DHHS to fence off outbreaks, and when they do that the virus in that area dies.

If however it gets away we are stuffed.

We seem to have transitioned from a reduction strategy to an elimination strategy - and the various Governments are focusing on eliminating it to the detriment of everything from businesses, the economy, people's mental health and even so far as their superannuation balance in 30 years time!

We have not transitioned; you would be told if we had. You only have to look at the person who started this thread, the pizza party goers a couple of nights ago and the two Sudanese who tried to run through the police cordon around the towers to know that some people have no idea of what the threat is.

However the containment policy Australia has been using has been spectacularly successful when you consider the original prediction of 50,000 to 150,000 deaths, and if the flattening of the Melbourne curve continues, and the numbers start to fall, and if NSW have the same success as they apply the same strategy to the Casula out break, and Queensland do the same with their current outbreak, we will have a control method a little like our fire brigades; if the Health people can get in fast, trace the outbreak and shut it down, Australia has a way forward to keep going until a vaccine is found.

As far as finance is concerned, it would be nice if we could afford to carry everyone forward to the end of the pandemic, and we aren't far off being able to borrow our way there.

Two bright lights at the end of that tunnel are the very rapid build up of business after Wave 1; perhaps a little too fast, but with good lessons for wave 2., and the soundness of the Stock exchange which has been pumping thousands back into our superannuation accounts so far.

Turbo, I have heard about sparkles engine technology. I thought at one stage my vehicle may have had one. However I found spark systems. Are they for starting, what can you tell about sparkless engines. Attached images is my engine with the cover removed

The first production of these is the Mazda Skyactive-X

It's called Homogenous Charge Compression Ignition (HCCI) where the mixture auti-ignites in an exothermic process.

Spark is not used to ignite the mixture but the system has its pluses and minuses compared to Otto or diesel cycle, and Mazda uses spark plus for part of the process and call it "Spark Controlled."

There is plenty on Wikipedia for the Skyactive-X, but you'd have to go to industry sites for the latest developments.

I think I can see 3 plus a bit of another spark plug actuators on yours; that's similar to the current petrol/spark plug engine.

I have been researching dual cycle engine after I noticed that mine has a relatively low inlet manifold pressure at full power. I believe that the manifold pressure for 260hp/lire@3000rpm may only need to be about 2bar. Consider the first part of the cycle, Otto cycle with a charge of full air some fuel ignited by the spark plug. Pressure extremely quickly rises. Normally in the Otto cycle this pressure would decay as the piston moves down. But now convert to diesel and inject fuel in a constant pressure diesel cycle. In reality it does drop but not as much as an Otto. The pressure vs volume graph shows this rise then not decaying as much. I have not read that this is the case, but seems plausible.

Diesel engines changed dramatically as designs were changed to meet emission standards. For example, a couple of decades ago fuel pimp pressures increased to over 2000 psi and we were told to warn operators not to crack injector unions to bleed engine because the jet of fuel could kill them. We went to common rail systems where the injectors were controlled electronically and today there are multiple injections before and after TDC - I've seen specifications for as many as 8. Valve opening and closing would have also changed radically along with intercoolers being pretty much standard, and in many cases duel in-line turbo chargers, the overall principle being to allow air as cold as possible into the cylinder as quickly as possible, heat it to make it expand for more power, ignite it and keep burning it (thus keeping pressure up) and then restricting it through the diesel particulate filter at the back end. All of that development has led to the latest sparkless petrol engines. Somewhere in all those changes is a mean pressure curve, and someone may have taken the time to work it all out, but to do what you want to do, you'd have to make sure you were researching the older material pre those changes.

The Scratchpad in OzRunways is handy for that.

In Metropolitan airspace there's often not enough time for that. A real RPT pilot doing the workload daily can train himself, just like a singer learns when to take a breath.

".....get in, sit down, shut up and hang on, and I'll explain how you fly a Bulltax" said Brutus who wasn't all that sure about which lever did what, but could .........

A problem I find with this discussion is that for people who don't live in the Melbourne Metropolitan Area, simply naming locations as in Turbo's post #80 has little information for the rest of us as we don't know where those places are.

It comes from the DHHS site which updates daily and has all the facts for Victoria

Department of Health and Human Services Victoria | Latest news - coronavirus (COVID-19)

The point was that allowing the protests to proceed sent a strong message that that social distancing precautions were no longer necessary.

It seems the strong message seems to have been picked up in SE Qld by people who don't have a clue about the whole story, including the social distancing practised and the reasons it went ahead, and who just want to push their own particular barrow. In Victoria we are communicated to twice a day by both the Premier and Chief Health Officer. These aren't ten minute sessions; they go into fine detail and incude both the Premier and CHO explaining their mistakes and corrective action, which is why they have had, and are still getting overwhelming co operation and support from Victorians.

I'm not personally concerned about CV19, but I do feel for Victorians who are going to be put through all that crap again and largely due to complete mismanagement and I'm concerned that if it gets out to other areas (which it probably will) that other states will go into lockdown again.

From the daily conferences, Victorians are aware of the casues of the outbreaks from the linkage between the Al-Taqua school to the Towers on the fringe of the CBD, to the outbreaks related to meet works, in fact hundreds of different causes compared to the few picked up and reported by the media. In fact the links I provided to DHHS are not rotating links, DHHS have left the statements up warts and all, mistakes and successes, and the cause of each outbreak, so anyone can go on there and see for themselves.

I'm less concerned about the disease than I am the governments response to it.

As has been patiently pointed out, until the emergency declarations have expired the CMO and State CHOs are the ones responding in terms of managing a pendemic where the only way of saving lives is to squeeze it into situations where it dies, so the best way to do that is identify its path and close that off, and Australia has been one of the most successful countries in the world. Personallt I'd say the governments have been exceptional at responding to what the CMO and CHO want to do to minimise deaths, but I guess there's always someone out in the sticks that thinks he'd have made a better Prime Minister or Premier.

It's not going away, and all they will really do is cause maximum pain by destroying everyone's livelihood (unless you're a public servant) AND they will eventually still have the deaths overall, just over a longer period.

In the past few months we've had to put up with thousands of predictions like this from would-be Epidemiologists, but we've been luck enough to have the real ones in charge.

.....Spartacus Cook who usually sat outside the Forum hoping .............

....goat bals, but was to no effect. Eventual General Maximus Turbinius ordered half a dozen Bultaxes and sent them into battle against the Philistines who were handy with slings.

"Height well away from us you must gain" he said in Latin, ensuring his eardrums didn't burst from the sound of a Bulltax on the climb. "Glide towards the enemy you will make" he continued, "throttle the you will widely open" he said.

And so it came to pass

The Bultaxes at wide open throttle sounded like a thousand virgins being rent asunder, and the Philistines fall to the ground holding their bleeding ears and crying "Help us Lord"

God looked up from his FB page and then down upon them and said "I work for the other side Bro's", and the General's troops put them to the sword, all except little ......
