Jet sizes[edit]

There are both compact and bus-size jetplanes. We should make multiple articles about different size jetplanes just like there are articles about different size automobiles. The article I am suggesting are compact jet and commercial jet. --SuperDude 00:18, 22 Apr 2005 (UTC)

  • Not a bad idea. There's an article at business jet but commuter jet and commercial airliner are coming up blank. I don't know if "commuter jet" or "compact jet" are proper terms, however. I personally don't know much about jet aircraft, but my younger brother does. I might give him a call. Let me know what you want to do on this, SD. - Lucky 6.9 00:56, 22 Apr 2005 (UTC)

First flight[edit]

Actually, the first operating jet was a British aircraft, the name of which escapes me.—The preceding unsigned comment was added by 81.101.101.78 (talkcontribs) .

Hi, I think the first british commercial jet was the comet -- Maj. Templeton —Preceding unsigned comment added by 76.64.204.143 (talk) 15:21, 9 September 2007 (UTC)

Coanda[edit]

The Coanda-1910 is listed above, but the Canadian biplane ca. 1912 is not. Reference needed: Older printed material on early flight.—The preceding unsigned comment was added by Roy.crabtree@gmail.com (talkcontribs) .

The Coanda-1910 was the first jet plane ever built, however, this article doesn't display its picture. Please display the picture of the Coanda-1910 jet plane. Template:Unsignted

No, see the arguments below. The Coanda-1910 has been very seriously challenged as to its supposed status as the first jet, a relatively recent claim. The acknowledged first jet is the Heinkel. Binksternet (talk) 21:17, 14 March 2011 (UTC)

First sentence[edit]

I changed the first sentence to plural. Sounded better. Spaomark 16:33, 14 December 2006 (UTC)

Aircraft is the plural per http://www.answers.com/aircraft&r=67 Kind Regards - Heligoland | Talk | Contribs 16:45, 14 December 2006 (UTC)


Space Shuttle aerodynamic lift during launch[edit]

I have searched around and can find no mention of this. Since the shuttle is more or less belly-up during launch, it seems counterintuitive that the lift surfaces would be of any help. In fact, it seems the opposite would be true. I would suggest deletion of this if the author can not provide citation. BigDaveB (talk) 19:26, 12 June 2008 (UTC)

co invented[edit]

Every book and article I have read on this subject matter, give each of these men credit, not just Whittle. I suggest that you rewrite, stating so. —Preceding unsigned comment added by 83.64.176.190 (talk) 17:07, 26 November 2008 (UTC)

History[edit]

The history section mentions that the first manufactured turbine jetplane was the Heinkel He 178 turbojet prototype of the German Air Force (Luftwaffe), piloted by Erich Warsitz on August 27, 1939. I've got an article by Sir Frank Whittle here in an old aircraft magazine, entitled 'Contact' The Magazine for Air-minded New Zealand. Feb 1954, which contains a section wherein he discusses this, relating to the question of whether the Germans flew the first jet. He writes that in the sense that they got one off the ground for a few minutes but that if it was a question of the first flight of an efficient and successful airplane then no, and adds that Britain was certainly first in the field. He describes the test flight of the Heinkel on August 27 1939, saying; "A tiny single-seater jet Heinkel -the HE.178-flew for ten minutes in Germany on August 27, 1939, four days before the invasion of Poland. What happened on that flight is a mystery to me; but the engine was not further developed, and the plane never went into production." No mention of the Italian test flight mentioned in this article either, but Frank Whittle would have been aware it, it apparently having been heralded internationally as the first successful jet flight at the time according to the linked article, and may not have counted it as a successful flight for similar reasons to the above. I think it's worth noting in the article, if he's correct, that the Heinkel, while the first manufactured jetplane, was not successful, only flew for ten minutes, and was then not continued. And maybe something similar for the Italian prototype test if details can be determined.Number36 (talk) 22:44, 19 March 2009 (UTC)

Coanda not a jet[edit]

Coanda's 1910 aircraft was an attempt at a ducted fan. He described it as such in painstaking detail in several patents (British patent #GB191112740(A), Swiss patent #CH58232(A), etc). Aviation journals and magazines which covered the air show described it as a ducted fan as well(Cassier's Magazine (1911) Volume 39, page 199; Popular Mechanics March 1911 page 359; Technical World Magazine (1911) Volume 15 page 615; Aircraft (1910) Volume 1 page367). Coanda didn't change his story and start claiming it was a jet until others had invented jet engines; and when did he had a great deal of trouble keeping his story straight. Does anyone really think he should be credited with building a motorjet when there's no evidence whatsoever that he did, and a huge mountain of evidence that he didn't?Romaniantruths (talk) 23:59, 2 August 2010 (UTC)

verifiable reffrences are needed in order to make an edit of the article. please understand if we don't take your word for it 79.113.9.72 (talk) 10:42, 5 August 2010 (UTC)

If verifiable scources are needed to make an edit, User 79.113.9.72, then I guess I'd better remove the totally unreferenced assertion that the 1910 Coanda was a jet. I know you'll want whoever made those assertions to please understand if we don't take their word for itRomaniantruths (talk) 18:02, 7 August 2010 (UTC)

The magazines referenced are all public domain and can all be found with a search of Google books. The patents are all also available on the internet, but just to make it easy for you here are some simple directions: Go to the Henri Coanda Wikipedia page and scroll down to the references. Click on The patents of Henri Coanda. Scroll down the patents until you find the patents I specified (the French one is there too! And if you can't read French, I think there's even an automatic translation available). Once you've read Coanda's own description of how his turbopropulseur works and seen his diagrams, please let me know if you have any evidence to the contrary other than his much later unsupported personal assertions, or re-iterations of same by lazy aviation historians. If you do find anything else perhaps we can discuss wether what you found should trump these primary scources in Coanda's own words.Romaniantruths (talk) 20:26, 5 August 2010 (UTC) And while we're at it, I notice that you've made quite a few edits to aviation articles without references(like the claim on the aircraft engine page that Jatho was the first person to attempt to fly using only on-board means, do you really mean that nobody ever tried this before 1903?). I don't spend a lot of time on Wikipedia so maybe you can explain why these rules apply to my edits, but not to yours.--With warmest regardsRomaniantruths (talk) 20:26, 5 August 2010 (UTC)

Coanda was a jet, acording with most of qualified scholars who search on the subject, and the endless talk on "Coanda-1910" page clearly show that. Fact that some unreliable and not qualified ones may disagree, its another thing, but we should stick with the facts and dont go with some stupid bias again and again, its unproductive and will just lead to a war all over all kind of wikipedia articles —Preceding unsigned comment added by 79.116.207.185 (talk) 14:13, 28 September 2010 (UTC)
Just as there are sources which agree that the Coanda-1910 was a jet, there are sources which say that it was not a jet; that it did not fly. Both sides of the dispute have good sources to cite. Our representation of the aircraft cannot state flatly that any of the disputed facts are indeed facts. Binksternet (talk) 18:15, 28 September 2010 (UTC)
Once again, this article cannot state with certainty that the Coanda-1910 aircraft was the first jet aircraft. Gibbs-Smith and Winter performed extensive historical research and determined that it did not fly, ever, and that it did not have combustion in the air stream, a requirement for flight in air, as without it there would not be enough thrust. No matter who else says that the aircraft was the first jet (quoting Coanda's assertion from the 1950s and '60s), these two giants of aviation history are enough to stop us from being certain. Binksternet (talk) 15:03, 29 September 2010 (UTC)
  • you're funny. If those are giants of aviation i am soviet cosmonaut. Only relaible and qualified to talk about Coanda-1910 are Stine, Craciunoiu, Antoniu, and i may add Boyne. All this not that just researched all Coanda documents and archives, but, unlike those 2 clowns, have too the qualifications needed to understand them. Gibbs was a delusional nut who believe in ghosts and paranormal and was good at searching for Bayeux tapestry and old stuff from world exhibitions too, and Winter was a former journalist with a degree in history. Compare that with a rocket scientist and author of aeronautic books, a former Air Force colonel, director of Air and Space Museum and aviation historian or phd engineer aviations who write aviation history books since decades, and who had acces to all Coanda documents and atents. Is this a joke from you to still promote those "giants"? Are you have a clear scale of values or you live in alternative worlds as your idol, Gibbs? —Preceding unsigned comment added by 79.116.206.207 (talk) 18:43, 29 September 2010 (UTC)
If you have an issue with Gibbs-Smith status as a reliable source take it to the appropriate forum for a third part opinion. GraemeLeggett (talk) 15:11, 30 September 2010 (UTC)
  • i think the problem is pretty solved, since even Gibbs agree in his book [1] that <<<Another unsuccessful, but prophetic, machine was the Coanda biplane ... Although inevitably earth-bound, this aircraft stands as the first full-size attempt at a jet-propelled aeroplane.>>> —Preceding unsigned comment added by 79.116.208.76 (talk) 20:12, 7 October 2010 (UTC)

Including of Coanda -1910[edit]

I will post some references (there is an abundance of them on "Henri Coanda" and "Coanda-1910" page, and i hope the personal bias of some peoples will not stop to be added

"Romanian inventor Henri Coanda attempted to fly a primitive jet aircraft in 1910, using a four-cylinder internal combustion engine to drive a compressor at 4,000 revolutions per minute. It was equipped with what today might be called an afterburner, producing an estimated 500 pounds of thrust. Countless loyal Coanda fans insist that the airplane flew. Others say it merely crashed."

"The Coanda effect is familiar to most hydraulicians, although perhaps not by name. The effect was first observed in 1910 by Henri-Marie Coanda, in connection with exhaust flow from an experimental jet engine (Stine, 1989)."

And there are more, i dont think is needed to put them all, and is pretty clear by now. So i propose an introduction phrase as:

  • "The first jet aircraft (fact still contested by some aviation historians-Gibbs) was "Coanda-1910", build by Romanian Henri Coanda and exhibited at Paris Air Show in 1910. It was considered an "experimental jet" or a "primitive jet" (see Stine and Boyne above), and used the same type of engine design as later "Caproni Campini N.1" and Japanese "Tsu-11". However, the "turbojet", the most common type of jet in use today, was invented in 30's, independently by Frank Whittle and Hans von Ohain".

I hope this sound good enough and is a neutral point of view who can be posted —Preceding unsigned comment added by 79.116.208.76 (talk) 06:37, 30 September 2010 (UTC)

According to the def. in dictionary, Coanda 1910 was a jet plane[edit]

Even if Coanda 1910 had used just a ducted fan powered by a piston motor, the overall engine fits the definition of a jet engine (see below) and in consequence the picture of the airplane has to be added. Coanda 1910 used oxigen to burn fuel and produced a backward discharge of gases that pushed the plane forward. This is in the definition of a jet engine.

"Definition of JET ENGINE

an engine that produces motion as a result of the rearward discharge of a jet of fluid; specifically : an airplane engine that uses atmospheric oxygen to burn fuel and produces a rearward discharge of heated air and exhaust gases" source: http://www.merriam-webster.com/dictionary/jet%20engine

"jet engine

1. An engine that develops thrust by ejecting a jet, especially a jet of gaseous combustion products.

2. An engine that obtains the oxygen needed from the atmosphere, used especially to propel aircraft and distinguished from rocket engines having self-contained fuel-oxidizer systems."

Planes with ducted fan engines can fly. Binksternet is wrong as usual[edit]

There is enough power to fly a ducted fan jet engine. If you do not believe just take a look at this aircraft that flew in October 1932. http://en.wikipedia.org/wiki/Stipa-Caproni

"Once again, this article cannot state with certainty that the Coanda-1910 aircraft was the first jet aircraft. Gibbs-Smith and Winter performed extensive historical research and determined that it did not fly, ever, and that it did not have combustion in the air stream, a requirement for flight in air, as without it there would not be enough thrust."(Binksternet) — Preceding unsigned comment added by 70.83.160.23 (talk) 20:40, 13 March 2013 (UTC)

Coandă-1910[edit]

User:MilborneOne Okay, we're here now. Can you please speak out? What's your beef with Coanda? Romanian-and-proud (talk) 19:00, 12 December 2015 (UTC)

Nothing, Coanda was a rather clever man in his field. MilborneOne (talk) 19:04, 12 December 2015 (UTC)

Then why did you delete the picture of his plane that I added? Romanian-and-proud (talk) 19:07, 12 December 2015 (UTC)

Because this is an article on the jet engine which the piston-engined Coanda 1910 is clearly not, refer to the Coanda-1910 article for more information. MilborneOne (talk) 19:14, 12 December 2015 (UTC)

It was still a start. I didn't even say what it was, I just put the picture and it's name, let the reader decide whether it's a jet or not. It was a precursor. Can you respect that and give it the place it deserves, namely on this page? Romanian-and-proud (talk) 19:17, 12 December 2015 (UTC)

Sorry this is an encyclopedia we dont add pictures for the reader to ponder over we use reliable sourced information. So as the Coanda-1910 had nothing to do with the development of the jet engine either directly or by influence then it would be misleading to add it. Refer to the Coanda-1910 talk page for more information, thanks. MilborneOne (talk) 19:35, 12 December 2015 (UTC)

How do you know it had absolutely no influence? Hm? Can you prove that beyond any doubt? Romanian-and-proud (talk) 19:41, 12 December 2015 (UTC)

Because jet engines dont work the same way as Coandas piston-engined Turbo-Propulser, have a read of the Coanda-1910 talk page not much point in repeating the same discussion here. MilborneOne (talk) 20:32, 12 December 2015 (UTC)
