Re: Don\'t Lock Your Props

John,

When you say "ships propellers" does this mean you ran the tests on the type of proppelers seen on large ships, or the type of prop found swinging from the average yacht? And would it make a difference? Logic suggests it might as ships props fill more of the circle that they turn in. (if that makes sense).
Fascinating stuff though!

It was a modelled ships propellor that showed the results when scaled, but it also showed them unscaled so it applies to all sizes in our opinion.

Re: Don\'t Lock Your Props

In your opinion does it apply to all designs? I ask because a proppeller designed to drive a ship across an ocean looks markedly different to one designed to push a yacht at 6 knots. So do you think the same effects would be seen on a two blade yacht prop as are seen on a (?) bladed ship prop?

Re: Don\'t Lock Your Props

Being a quantum effect it will apply to everything that rotates in sea water (and maybe even if it just has a flow over it).

Re: Don\'t Lock Your Props

Ok, thanks for the info!
I think a trial with some flat water, constant wind and a log is called for!

We here at Ship Hydrodynamic Investigations and Technology are most upset over your unkind suspicions Nigel.

Kippers maybe, but never mackerel /forums/images/icons/smile.gif.

Who is this Aether bloke? It's not the Aether Pendragon of historical note is it? Or is it King Aether of Tintoggle the famous hydrodynamicist and hairdresser who invented Curls by winding up the hair on his quantums?

Re: Don\'t Lock Your Props

Er, no. Like the aether (sometimes aka ether) that it was considered light propagated through in a vacuum.

The Michelson-Morley experiment proved that the aether wind did not exist - there is a very good description of that at <A target="_blank" HREF=http://www.phys.virginia.edu/classes/109N/lectures/michelson.html>http://www.phys.virginia.edu/classes/109N/lectures/michelson.html</A> for anyone with a modern physics bent.

Like Rob_Webb, I was also originally trained as a physicist.

Apparently in the Thelfarm Isl in the South Pacific Fray Bentos is worshipped as the local god.

Cargo Cults

Hadn't heard of a Fray Bentos cult, and Google won't oblige. However:

"The Yaohnanen people of Vanuatu raised a worshipful cult for Prince Phillip of Britain. They have prepared a home for him and women have volunteered to be his wife if he would but come and be their god and bring to them the ostentatious riches of the British". Read all about it <A target="_blank" HREF=http://www.jasher.com/Cargo.htm>here</A>.

Surely it can only be a matter of time before there is a Claymore cargo cult, with a group of winsome South Sea Islanders bowing in adoration of the Holy Cauli?

Re: Cargo Cults

Apparently the FB cult started in the early 20th C when the Thelfarmers were starving and a cargo ship loaded with the FB delicacy sank and some of the cargo was washed ashore. This saved the simple stone age tribe and now they worship the containers. Apparently a 78 of Harry Lauder was also washed up, must have belonged to the Scots engineer on the doomed St Edakienky an Estonian freighter, and this is currentlt held to represent the chief god as its round and black with lots of lines.

Re: Cargo Cults

Amazing, what you can learn on here.

A poignant story; the Thelfarmers must, indeed, have been on their uppers, and I can see how the sight of the homespun blue and yellow tin would have awakened all kinds of emotion amongst the starving islanders.

The name St Edakienky rings a bell somewhere. Her home port wasn't San Beftory, was it?

Better Harry Lauder than Jimmy Shand, I guess.

Re: Cargo Cults

Acshually the life giving properties of the cans were not recognized by the thelfarmers until several years after the wrecking of the St Edakienky, when their homeland was visited by a desperate Bettaware salesman. Amongst the baubles and trinkets in his possession was a simple hand held can opener, which he proceeded to demonstrate upon one of the holy cans. As the succulent aroma of the FB pie filled the air the Thelfarmers found themselves overawed by the power of this fresh faced youth. They bowed down to worship this omnipotent being, whose name, when pronounced in their dialect, was Mystic Hen.

Mystic Hen lived with them for many years, enjoying their adulation, meat pies and virgins, until once more he heard the call of the sea. Gathering together teak logs from the forests and pitch from the bogs he built himself a manky new boat, which the islanders christened Twi Ster (trans: Bringer of the farts).

There stands to this very day, on the summit of the island's central mountain, Fell Doon, a cairn formed from empty FB cans, surmounted by the holy writings of the Bettaware catalogue.

Unfortunately, the supply of pies being quickly exhausted, the Thelfarmers passed into extinction long before a re-supply mission led by Capt. Findus McFishfinger arrived.
