Although my VTOL is a Hybrid and not relying on batteries, here is a link to some very forward thinking by Volvo and other European companies.

http://www.wired.com/2013/10/volvo-supercapacitors/

Imagine all the fuselage and wings of an aircraft made like this.

The rapid advancement in lightweight, high power brushless electric motors is the key to this type of aircraft; any other type of propulsion kills it off with excessive weight.

I have had a passion for ducted fans and shrouded props for over 20 years and about 11 years ago I roughly sketched up this design but couldn't get over the weight problem,

having to use shafts and right angle drives and reductions etc.

After watching the Avatar movie in 2010, it got me all fired up and motivated to revisit my design (which at the time didn't look like the finished version).

Now that there are brushless motors of up to 80hp and weighing less than 15kg, with almost 95% efficiency; almost anything is now possible.

And with the big advances in lightweight batteries, which keep coming every couple of months the future looks very electric.

Mark, if your trip is about 2 to 3 months away, then yes.

I wouldn't like to show anyone a half finished project.

I have had discussions with CASA and at the moment they don't know what it would be classified as; but it will more than likely be administered by ASRA

The MTOW will be <600kg.

Well, its been a bit over 6 years since I started this thread and it looks like there is no development here in Australia

for VTOL aircraft; other than what I have been doing.

I have been working very hard on my 2 seat Hybrid VTOL design which is ready for the 1/3 scale Proof of Concept model to

go into the testing stage in about 3 to 4 months.

The whole design is under Patent Pending and therefore all intellectual property is protected.

Until the full Patent application has been filed I will be restricting any replies to basic information only, so please don't be offended

if I do not answer you questions to your satisfaction.

I hope you like what could be the new era of aviation!

Would anyone know if there is a standard document available, outlining the Safety and Operational procedures for airfields specifically used for Recreational Aviation operations?

This is where the West Maryborough Airpark development will be.

The yellow line is 900 mtrs.

I think he said it was about 800 or 900 mtr grass strip; there could be up to 60 blocks from 2500 sq/m

About 15 K's west on the Biggenden/Maryborough Rd

It's been a while since anything was added to this thread and rather than starting a new thread, I thought it may be of interest to some of you that the Airpark that was proposed west of Maryborough in Queensland back in 2008 is now in the final stages of being prepared for council submission and from what I've heard, the Fraser Coast Regional Council has looked favourably on this new proposal.

The only reason it looks like being approved this time is because the unworkable development legislation that the Bligh Government implemented has been removed.

It's about time sanity prevailed.

Let's hope more councils around Australia will take note and get behind more of these Airpark developments.

A good friend has died in a paramotor accident in Queensland's south east this morning.

Chris Atkinson was a very experienced pilot and a world record holder of many records.

It's too early for anyone to know what caused the accident but it will be investigated.

My my heart felt condolences to Chris's family; a great guy who will be sadly missed.

Isn't it marvellous how a plane that has been around for about 15 years and failed to hit the mark, now has people jumping out of their skins just because the front windscreen was changed and a radial put up front to make it look like an 80 year old plane; (which hopefully will get a lot more support and sales than the original).

The original plane itself was a great plane and a credit to it's designer/manufacturer and I have always been bewildered why their wasn't as many of this great design flying as there are Jabiru's especially here in Aus.

I don't know if it was a downfall in their marketing strategy or what that failed to get the original into the sky in masses but I do hope this new formula is spot on.

I have known the designer/manufacturer for years and he is a very nice guy who has done a lot for recreational aviation in Australia.

And NO, I will not disclose any more details about the designer and the Stinson project, all will be revealed soon by them in due course.

60% T28 Trojan

It would be:

Length; 20ft

Wingspan; 25ft

Height; 7.7ft

Engine would be 110hp radial.

​I'm seriously considering it.

Can anyone tell me the designer or current owners name of this single seat ducted fan aircraft that was built in either NSW or Victoria possibly about 10 years ago.

I did have all his information but since many house moves, I have lost all the info.

I don't know if it ever got registered.

Hi Stanzahero,

I had diesel on my mind while typing that, they call it a "Grey Moment" these days don't they.

Thanks

Sorry Mick,

I misunderstood you.

With your experience in RC aircraft you would know that any engine in miniture will have many more problems than an engine that is built 5 or 6 times larger; in a larger engine you get bigger and better bearings, better machining finishes and an allround more robust engine.

I came across this quote and I think it sums it up beautifully;

New Technology goes through three stages:

First it is ridiculed by those ignorant of its potential

Next, it is subverted by those threatened by its potential

Finally, it is considered self-evident.

Hi Mick,

Why are you comparing this engine to RC engines. From what I've been told this engine was designed from the ground up to be used in any number of uses, Hybrid cars, motorcycles, jet skis and recreational aircraft.

As you say, a couple of the design features in this engine had been tried in RC engines but with limited success, but as far as I can assertain the designer of this engine has overcome those problems and I would take more notice of an engine designer/builder with 32 years experience than someone who only sells RC engines.

When you say; "This info came from an employee of said company." do you mean the company that is building these Rotary Piston Engines or the Australian RC engine distributor.

Hi Yenn,

There has been a lot of advances in diesel technology in recent years that contradicts the standard configuration of a compression diesel engine.

There are companies who are converting petrol engines to diesel using the spark ignition process but they use very high pressure injectors (160,000 PSI) and the engines usually run between 12 and 17:1 compression ratio.

They also have the added advantage of eliminating diesel knock and pre-ignition which is a habit in traditional diesel engines.

Here is an Australian company who uses this technology;

:: Green Diesel ::

There has been a lot of development in diesel technology since Nicolaus Otto designed the diesel in 1861.

: WOW! to this engine

Andy,

I asked your question about the engine cutting out by itself and the photo shows the kill swictch .

The other photo shows the air-cooling vents and in the circled area you can see the cooling fins on the rotating cylinder.

I found out why the engine run's are so short in the video's; that engine is the Proof of Concept engine and is not fitted with an oil system and it runs on a teaspoon of oil each time it's fired up.

They said they are currently working on a full test version which is 250cc and it will be fitted with a dry sump oil system, starter motor and an alternator and they will be rigerously testing it to document all the performance figures.

Also the engines they are considering for Recreational Aviation were;

250cc 20/30HP 140mm dia x 305mm long 8.2kg weight (W/O starter & alternat.)

500cc 40/50HP 178mm dia x 343mm " 10.0kg " ( " )

750cc 70/80HP 210mm dia x 381mm " 15.9kg " ( " )

1000cc 100/110HP 247mm dia x 432mm " 20.9kg " ( " )

MAET said these were estimates at this stage, but the figures would be very close.

The 750cc and 1000cc will also be available in Turbocharged and all these engines will be Spark Ignition Diesels.

Any more info you would be better off talking to them direct.

It looks like someone has finally gone outside square.

This engine could be the ultimate for aircraft in the years to come; it can be scaled to any size, is very fuel efficient and has extremely low emissions AND SMALLER THAN A TURBINE.

The engine in their video is a 150cc Proof of Concept engine and puts out 10HP and weighs 6.3kg

Check out the videos; it may be a year or two before they're available, but I cant wait; and the aircraft possiblities are unlimited.

Sue,

Who was your better half talking to, I think he is very misinformed.

I know for a fact the current owner is the developer and it is still being delt with at the council and I was speaking to the owner earlier tonight, and he has owned the property for the last 5 years.

David,

I think you are right but, an ICE engine also covers a rotary which is not a piston engine.

I'm sure the term "Internal Combustion Engine" was never intented to be used for Turbines.

Graeme

Sorry David,

Standard installation of engines in the port & starboard wing

Graeme

Yes HEON that is correct, but you can only have one ICE (internal combustion engine) and one prop.

The only way to change these regulations is by constant lobbying of our representatives.

Graeme

It would be good if that was the case but ufortunately it's not.

It is one (1) only piston engine allowed and one (1) only propeller; you can't even have a single engine driving counter rotating propellers.

Until CASA allows twin engine installations up to the equivalent total HP of the maximum allowed for the category, then a lot of engine-out accidents and fatilities will continue to happen which could have been avoided.

That's my opinion anyway.

Graeme
