Okay, now if somebody has something related to Coanda's 1910 plane, please post it. If not, please don't do.

I apologize again for the hard vocabulary but I was very upset reading the Coanda defamation.
I am living in Bucharest and yesterday I visited the two places where Coanda is exhibited. The
Military Museum and the Aviation Museum both under Defence Departament management.
The great surprise came finding out that "a huge archive of Coanda's original pictures, blueprints
documents and letters" partially untouched is awaiting to be researched and I started the procedure for research permission.I will write a true story book based only on documents .
Another news :next year for the century aniversary of the first jet flight, a 1:1 replica of the
Coanda 1910 is made with the intention to be flown !
Next time I will poste few original pictures and texts !

Great to read this! Thanks for your apologies, and I'm really looking forward to reading about your findings!
 
nemisisthebest, anything further on this?
Hopefully you have managed to secure permission to look at the original documents. Do you have anything further that you can post here?
 
I have been reading all the controversy surrounding Msr. Coanda and his "reaction engine" aeroplane...

I have been reading and studying his work since the 1950's, when articles were published about his projects in Canada, so it's NOT coloured by the '70's - '80's propaganda...

First of all, lets deal with the whole "jet" engine definition...

A "jet" does NOT automatically assume a "turbojet" or any specialised form...

All a jet has to do to qualify as a jet is to intake and then eject the ambient medium at a higher velocity or increased mass to effect the forward propulsion of the vehicle to be properly called a jet...

After all, "jet" boats and jet-skis are real jets, and they are not turbine driven and use water as the ambient medium...

A rocket, on the other hand, mixes its fuel and oxidiser internally for the reaction mass. A rocket is a special case of "jet" that precludes having to use the surrounding medium...

A "turbo" or turbine driven jet uses a bladed turbine motor to power the jet...

An octopus uses a jet, of ink-coloured water, to make its getaway...

A pulse-jet uses a series of controlled explosions to create the energy to expel the burnt fuel-air mixture...

A ram-jet uses the forward motion of the aeroplane or other vehicle to compress the fuel-air mixture before ignition...

Your "ink-jet" printer compresses and then expels the ink onto the paper...

The jets in your carburetuer squirt compressed fuel into the intake manifold...

The one thing that's common to all of them is that they expel essentially heated or compressed air, water or other medium to propel the device...

So, by the proper definition, the Coanda "jet" engine was, indeed, a jet!

Now, as to the specifics:

Coanda actually designed his first jet in such a way as to ONLY HEAT the exhaust gases and entrapped air before expelling them for the thrust...

It was later that he discovered that by an admixture of burning fuel into the compressed stream, he could achieve increased volumetric efficiency...

Both would be considered "jets."

By the way, the spiral-louvered opening in the front of his engine that misled reporters have been calling the "turbo-fan" was actually the iris intake control that controlled the mixture of input air mixing with the exhaust gases...

Whether or not his was the "first" is still a question... there were many people experimenting with the new concept of aerocraft in those interesting times... I will leave that up to historical experts, but let's, at least, get the technology correct...

An excellent contribution which puts Coanda's work in the proper perspective. Thanks for sharing and welcome aboard!
 
van, I dont suppose that through your years of investigation you have any interesting drawings and or photos of the engine or the overall aircraft?
 
The Coanda page of Wikipédia has an interesting paragraph on the Coanda 1910, at least for what is Inside the bolds :

Contemporary sources describe the Coandă-1910 as incapable of flight (Aircraft [1910] Volume 1, page 367). Years later, after others had developed jet technology, Coandă started making claims that it was a motorjet, and that it actually flew. According to Charles Gibbs-Smith : (…) the machine never flew; it was never destroyed on test; and Flight noted that it was sold to a Monsieur Weyman" (Flight, 14 October 1960, page 619). Gibbs-Smith continued, "The claim said that after a disastrous crash (which never happened) Coandă wished to begin a 'second aircraft', but 'his funds were exhausted.' Within a year he was ... exhibiting (in October 1911) a brand new propeller-driven machine at the Reims Concours Militaire..." (Flight, 14 October 1960, page 619) Other aviation writers accepted Coandă's story of his flight tests with the Coandă-1910.

I did not know the sale of the Coanda 1910 to Mr. Weyman and, effectively, the lack of funds seems not logic with the building of another plane immediately after the Coanda 1910.

Friends of mine have an old book, in French, on Aircraft (from 1911, as far as I remember), and I saw the Coanda 1910 on it (I Don't remember if it was a drawing or a photo). I will try to read the excerpt on the Coanda 1910 on their book.
