That would be interesting, although I don’t read Romanian! What was the original source for the schematics?

Sorry for the guys [Ian, Nemesis, JDK,etc] who forces the discussion into a completely other (and wrong) direction.I didn’t read they’r full posts (simply can’t) but I hope they are not Romanians.

Henry Coanda’s airplane was at that moment a really futuristic design.
As someone said before, it seems that after the test of this airplane he discovered the so called “Coanda efect”.

But for sure we can not say he invented the jet engine.
A good source of information for me was an old Romanian Models Magazine named “Modelism” where are some detailed schematics of the plane and ducted fun propulsion.There were also some engine cross sections which helps to understand how it works. I have this magazine pages scanned.

I’m afraid that I need to dissent from JDK’s “Insulting heads of state is not a good move to winning supporters.” If the head of state in question’s not elected, then I’m all for it.
As for the rest, though, spot on.

Dear Ion Nemes,
The lift of the plot of Hamlet from preceding ideas by Shakespeare is well documented – and serves well as an illustration of the tough reality of the world which intilectual property protection only seeks to mitigate. We remember Shakespeare – not the previous authors – because of what he brought to the existing story.

Ideas are actually cheap, perhaps sadly. Success takes luck and determination. Coanda is appropriately credited for his ideas, and is rarely left out of the story. However it remains a fact that it was von Ohan and Whittle who brought the jet engine to practical fruition – Coanda did not change the world by developing his ideas, and you are trying to hard to reverse the modern jet engine designs into Coanda’s concepts, not to mention lacking understanding about what patent expiry means.

More importantly, being casually offensive on a racial and nationalist basis does your view no credit – following up with rude remarks about particular people is heading towards libel. Insulting heads of state is not a good move to winning supporters.

Unless you can adhere to the most basic of good manners and refrain from libel, I’m afraid there’s no point in trying to continue the discussion. More broadly, if you continue to be so rude and aggressive you’ll continue to find your overtures for understanding and employment rebuffed – and rightly so.

I wish you a more open minded and less nationalistic new year.

All modern jet engines are in fact “thermojets” because the use the “double flux” technology .
The central air stream ,after burning chamber ,is too hot to hit the turbine directly and is mixed with the second
colder stream . A turbofan technology uses a third air stream ,much larger , produced by a ventilator and heated by the main exhausted jet !The efficiency increases when a greater volume of air is propelled with a reduced speed unlike the “pure” jet device ejecting a smal section,hot and high speed stream !This explanation is for those who mitigate the real value of Coanda’s invention.
I totally disagree with the imperialist opinion that “the winner takes it all” by any mean…
Now days a bastard British burgler (Dyson) ,was made “sir” by the pervert old lady for two stolen inventions from Coanda:the cyclon bagless vacuum cleaner and the bladeless fan.The shameless guy claims
he is a “great British inventor” but in fact, there is about Coanda’s old patents .He said he has no legal obligation to mention the name of Coanda .Yes, the patent rights are expired but the IP rights never expire.What would be if I copy “Hamlet”and make money for a book with the
same content but signed by myself ?Are we all creazy became ?
I want also excuse me for the hard words used ,especially to the honest working people, not to
the thievs and burglers.
A Happy New Year 2010 !

Yes, I did see that, Ian, and Nemesis isn’t doing himself any favours here with that sort of talk.

As a resident of perfidious Caledonia, I don’t have any problem with being abused as an English speaker (“See you Jimmy”), but have we all become so polite (or enamoured of the’30’s) that we ignore casual anti-semitism?

Ah, Brett can have the accented ‘Coanda’ in his text, but I can’t in a reply. Teach me to try and be clever with accents.
