 NSW, the origin & continuing spreader,of our current CV19 outbreak is not & has not, been under any form, of what I would consider, to be a true quarantine/lockdown.

The conditions for successful quarantine have been know for 100's of years - this knowledge has somehow been overlooked by the Scomo/Gladys teams.

The rules for a proper quarantine are quite simple - no one must leave their home/local (very few exceptions).  I understand, in this modern era, when we are all so dependent on others for daily existence,  that certain very few professions must continue eg emergency responders/police/medical practitioners/electrical/water/sewage/ food supply. This does not include priest/rabies/mullahs/removalists/real estate agents/ construction workers (except in an emergency situation)/ fast food outlets/etc - the list of, supposedly essential, workers goes on & on - is it any wonder that CV19 has spread interstate & to remote Australia?

If you want to do the least damage to the econamy you must aim for a short sharp (comprehensive) quarantine - this long drawn out NSW affair of a quazi lockdown, is doing untold damage to our econamy and its people. 

We will never know for sure, however there is every indication that if the Glady's team had done a proper lockdown,  when the limo driver was identified as positive,  we would not be in the situation we are today.

Sure Delta is more infectious - so was the plague. The Scomo/Gladys team are promoting vaccination as the "get out of jail" solution - why? cause it hides their incompetence.

I would speculate, that even with a true (whole of population)  80-90% full vaccination, this virus will continue to cause significant social/economic disruption for years to come. It will be a combination of high % vaccination AND fast well targeted management of outbreaks, that will minimise this. The latter skills being, demonstrably absent from the Scomo/Glady team.

I like nev's point about how tip speed and ground clearance considerations are the only reasons to consider a 3 blade prop.

If it was wings, the 3 blade is a triplane and the 2 blade a biplane. If the balance forces were not so big, we would see more single-blade props I'm sure.

It is always the ability of the prop to efficiently deliver engine power within the limitations of clearance & tip speed;

Should tip clearance (ground or fuselage) be a limiting factor, additional shorter blades, describing a smaller swept circle (increased clearance) may be required.

High engine powers, require larger props  that then may result in excessive tip speeds (less efficient)  and the above problem, so multi blades may be the solution.

High RPM direct drive engines (eg Jab) may require shorter blades to stay within effective tip speeds - the shorter blades may need additional blades to make best use of available hp.

Agree with gusto, Skip. Will reply on the Off Topic forum.

How does one get onto this  "Off Topic forum" ?.

Educated in N Ireland in the Public (Protestant) system - thought I was leaving the stench of sectarianism behind, when I came to Au in the 1970's -  only to see the rise & rise of Private (religious) schooling - cant be good.

When tough economic/social times come (& they will) the tribal/religious indoctrination will rise like an infection, with each tribe polarising & looking after itself.

The result will be disastrous  for the social cohesion of our country.

I am not against private schools of any kind, as long as they meet the minimum education standards of the State and dont get a $ from the tax payer.

It was a very very bad mistake to allow tax payers money to be used to fund private schools of any description.

I have often observed that when judging a persons career; its not where you start, its where you end up, that matters and even more importantly how the individual feels about the life they have lead.

would you rather fly a spitfire or a cirrus jet?
would you rather have an Ferrari 308, or a modern hot hatch?

the newer stuff is far more functional and performs better....
but it doesn't have the same emotional appeal

Fair comment - hard decision.

I would love to have a go in a Spitfire (even better would be a DH Hornet) but I suspect the reality would soon catch up (noise , vibration, fumes and uncomfortable seat) and the Cirrus Jet would be my preferred mount to actually  go places.

Cant say I give a toss about the car selection. One of the most fun cars I ever drove, was probably had the lowest HP - a "Bug Eyed Fright"  (Austin Healy Sprit) that I briefly owned back in the 1970's. The illusion of speed (your arse was only inched off the ground), the almost ridged rear suspension, making every ripple, pebble, pot hole a distinct memory, the wonderful precise (non power) steering, slick little 4 speed box, the mighty roar of the 1099 cc, 4 cylinder, twine carb, fanging through the Cotswold lanes at some horrific speed - peeeerfect!

yeah, I learnt it from a chat with my brother.
He wanted to buy a motorcycle, I had a couple spare at the time that I offered him full use of (just pay rego)
his response is that while he knew it was reliable and higher performance... it just didn't have the look he wanted when he saw his reflection in the window.

And he is completely right, at the end of the day we do this stuff because of how it makes us feel. if we were chasing numbers we'd jump on a commercial flight instead.

Really!!!!!?????

I guess it takes all sorts - give me function over form any time.

can we all just agree that they win in the all important wank factor.
lets face it, at the end of the day being able to look back at the aircraft and have bragging rights important.
we are all a little vein. and there is the old adage, if it looks good - it'll perform good

 

Weeellll sort of. We now have plenty of aircraft in the light sport/RAA class, that are so sexy you might just want to date them but do they deliver the expected performance?? Some but most don't.

If you prioritise ramp appeal over performance (form over function), you will be super happy with the ultra sexy ones. They still fly of course,  but your expectations in the performance area -  stall speed, empty weight, fuel consumption & capacity, range, climb, & cruise speed may not quite come up to expectations.

MY apologies Kyle - I reviewed the video and see that I was mistaken - it is the same aircraft.

Rest of my observations stand.

First video out on the new Constant Speed Prop

 

 

Sorry didn't want to duplicate the video - just to talk about the figures posted at the end.

Some points:

The two props not used on same aircraft  - hardly a good comparison. Nor is the lack of data  for aircraft weights,  fuel loads, multiple tests results . etc etc

I am impressed by the weight of the E-prop  but given the above comment, hard to see the actual real world  advantage of this feature

It is usually accepted that a 3 blade propeller is likely to give greater initial acceleration, thus providing shorter ground role and often better initial climb performance - so no surprises here.

What I would ask is why no better at cruise speed 3-4 kph to the E -prop is very disappointing ? as is a 7 % fuel advantage.

Like Thruster88 - I would like to see some comparative data with ground adjust props, including E-prop.

SKippy - ROTAX say that is a MINIMUM OF 5200 @ STATIC RPM ( WOT  of course). 

RFguy - you seemed to have missed my point(s) ;

We are talking fixed pitch (which includes ground adjust) - you just muddy the waters when you bring in CS comments

Static is always WOT (as far as I understand)

If you follow Rotax recommendations, static should be 5200 rpm - with care this may be reduced slightly but pilot management, particularly in climb,  becomes more critical, that is if you want to look after the engine.

Of course the climb out at full throttle (WOT) will result in an  increase in rpm - that's what you want for best climb performance - to 5800 if you so desire OR if you understand that climb angle can be used as a governor, you can increase/reduce angle, to control rpm/prevent overspeed and stay below max 5 minutes at 5800 if you wish. This should be part of the pilots engine management skill set.

However I do not see how you can pitch your prop to achieve an inflight cruise WOT of  5500 rpm (or whatever) and still expect to see 5200 rpm static.  I am not even convinced that this is even a desirable objective given the astonishing number of runaway Rotax 91 engines.

To suggest that a Rotax 91 set for 5220 static will somehow unload/overspeed in level flight is just to suggest there are pilots who do not seem able to manage their engine.

Just a guess. It is probably easier to see the build quality on a metal aircraft like the RV compared to a composite aircraft were you may not be able to see what is under the skin. Also as it is the most produced kit plane there is more chance of finding someone with experience who can guide a novice purchaser.  

As I understand it there are basically only 3 types of kit/[plans builds:

• All metal - One of  the traditional build materials. These days often include a lot of composite for those more "difficult" 3 dimensional shapes like cowlings, wing tips, fairings, etc. Metal kits lend themselves very well to advanced kits, where many of the components are built to "matching" holes and to production where CAD & automated/robotic "cutting" can mass produce parts (eg the  RV fleet). Metal can be complimented by plastic/wood/fabric.
• Wood - Probably the original material for kit/plans built aircraft - Can me all wood, or matched with fabric. Often plans built.
• Composite - Historically there are very few successful composite kit aircraft, probably due to the difficulty in making parts/components without molds (carving foam, etc). Then there is the potential health issues due to exposure to resins etc. The older kits also tend towards higher finished weights and individual handling characteristics. On the flip side recent composite aircraft are almost all extremely advanced kits.T he aircraft airframe comes as near finished components, that have been built in a mold, cured in an oven and have a high degree of conformity to original design and between completed aircraft. Arguably their build "integrity"  is compressible to factory built. They tend toward very simple "no brainer"  assembly. Often the finished aircraft are higher performing for their class/category.  Can be expensive

Bang for buck ya cant go past an RV. Occasionally you see a part built kit  for sale, being all metal is an advantage.

Agree, if the small minority of selfish people could just do the right thing for a couple of weeks, we'd be done with this by now.

I wish I had your confidence. Just heard on the news that a an infected construction worker has traveled from Sydney to Dubbo (I think).

As long as Gladys does not understand that a real quarantine lockdown requires as close to nil movement of people as is possible, we will continue to see outbreaks.

Just looked at some of the rules for travel within NSW;

• You can still travel to your second home ( may be required to justify this eg your partner lives there) - that's okay then, just take the virus to home No 2,infect partner who lives & moves within  that community
• You can still travel to buy/sell a house - Gladys didn't learn from the infected house buyer who traveled from Sydney to Batman's Bay
• Priests and other mumbo jumbo types can travel to conduct "pastoral" care - obviously God would not let them catch/transmit CV19
• All sorts of jobs (that cant be done at home) can go about their business - CV would give them a disease free passage

Gladys is in full avoidance of appalling management mode - none of this is her (teams) fault - Delta is just so infective - who would have thought (the rest of the World must have been keeping it a secret from the NSW Gov)- the jab will save us ????

Sooo : which one is the epidemiologist?? virologist ??? any qualifications that may be relevant???

As unmodified Rotax 91 series engines do not have mixture control I suspect LOP to be of only academic interest in this conversation.

As Garfield said, comparing EGT between engines is not really a "valid exercise"  - I take from this, that what is of use is the EGT readings for your engine, during particular operational phases (eg climb, cruise) over time and between cylinders. keep a log and respond to significant changes.

The info in my post above was to remind people to consider radiancy for a break / failure in the throttle control. By pitching for 5,500 to 5,600 rpm max with carb throttle levers set with springs to full open throttle you can fly along all you like. If pitched for 5,800 you need to shut down engine within 5 minutes as per Rotax instructions as longer than that results in damage to the engine. Such must be kept in mind with Rotax engines.

Perhaps you would explain how you can pitch for wide open throttle (WOT) at "5,500 to 5,600 rpm max" while addressing/keeping to the Rotax recommendation of 5200 RPM static ??

AND

As a possible solution to concerns about  a runaway throttle  situation, is the push/pull cable, that does not rely on a spring to open or close the mechanism.

It would be easier to understand the props if you gave prop rpm and not engine rpm.

My guess is that there is about a 2:1 reduction.

I spose the tacho just gives the engine rpm.

The "direct drive" aficionados will be confused by the RPM's quoted - not so the geared mob (Rotax) and yes the tacho is giving engine RPM. Rotax prop RPM read out may exist but I have never seen one.

I am sure Spacesailor will answear for himself however I would point out that political manoeuvring/shenanigans is incompatible with the running of a true quarantine effort ie you play politics and you ensure the failure of quarantine / lockdown (NSW).

Not so much - the French authorities were maintaining a system that protected the elite ruling class, in such a way as to ensured poverty in the masses  - this sort of elitism (USA take note) will almost always leads to descent/revolution.

As far as head tolling - both Scomo & Gladys have demonstrated a level of incompetence that would have been hard to imagine befor CV. So my money is on both of their heads ending up in  the basket.

FB - It beats me how such a risk averse individual, can drive to the airfield, let alone take to the air.

Its true some corners have been cut to get these particular vaccines into our arm's but they are hardly new technologies, so when the need is so pressing, it make sense to hasten carefully, to achieve what will certainly be the saving of millions of lives.

Of course, if you believe that CV19 is some forme of plot, to do unspeakably wicked things with your pristine body or that it is just some sort of mind game , you are not going to be persuaded of the "common good" in having the vaccine.

If and when we achieve herd immunity (80+% of the total population, including children & the no vaccination for whatever reason mob) you will benefit from the miniscule risk the rest of us have taken - hope you will be so grateful that;

A You leave your entire estate to a teaching hospital

B You write a heartfelt thank you to your fellow pilots/Forum members

On the other hand if I turn into a tumour riddled/blood clot/mental vegetable as a result of the  Astra Zeneca  (or future vaccine developments) I will make my craven apologies to you and all who sit on the fence with you.

The definition of apathy - Being Neither For Or Against

Reference: Australian Quarantine

I also believe it would be feasible & desirable, both in implementation & in cost/economic terms, for Australia to aim for zero CV19 circulating within its population;

• Australia has the good luck to be an island. With the exception of its northern boarder with PNG, its watery boundary is a great defence against natural spread of the virus
• The CV19 vaccines are not the "golden bullet" that will allow us to return to normality, without on going improved quarantine systems/responses.
• Israel is already experiencing reduced vaccine efficacy in those that were vaccinated 6 months ago. It is fare better not to unnecessarily challenge your vaccinated & unvaccinated population by "opening the boarders"
• Proper and rigidly applied, to ALL incoming travellers, quarantine systems (including CV vaccination) would need to be implemented. Sure there would be some "escapes" through human error and criminal behaviour, however immediate strong action (ie NZ response, dont put the Gladys team in charge) to contain the outbreak would see minimal disruption to the econamy and community.
• In the event of an escape, PROPERLY EXECUTED lockdowns would likely only last a few days- 2 weeks, minimising the impact on the econamy & society. 
• I do not see that it is desirable that we add another endemic virus (eg flue) to what is already circulating, when clearely we dont need too.
• Neither do I see the unnecessary cost of increased hospitalisation, lost work hours, as being acceptable. We still do not have a full understanding of how this virus will impact us (national/individual) in the long term (Long Covid?)
• It may be desirable to reduce the cost, to the tax payer, of having a large elderly/retired population, by increasing mortality rates (eugenics?), but as a 69 year old, I like to think I have quite a few good years ahead of me to enjoy life/flying

Idle thought - with all the negative reviews that ait craft "brokers" get (I also had a bad experience) are there any positive/happy customer reviews out there??
