Junkers[edit]

Did Junkers really do more to promote and develop the monoplane than others? He didn't make the first monoplane, that's for sure. 05:18, 16 September 2009 (UTC)

He did actually design the first practical all metal low wing cantilever monoplane - and it is this type of monoplane that eventually superseded the biplane. --Soundofmusicals (talk) 22:58, 16 September 2009 (UTC)
Sure. But he didn't do the first monoplane, the first successful monoplane, or even the most common early monoplane. His "first all metal monoplane" did not usher in a new revolution of metal monoplanes, the world continued to use wooden and metal biplanes for many years. Even the article on Junkers does not say he helped end the era of biplanes with his new advanced design. So why are we giving him credit? 07:12, 19 September 2009 (UTC)
The era of biplanes was effectively ended when cantilever wings and all-metal structures became common. Until then biplanes had real structural advantages, and tended to be much more controllable, especially in the lateral plane. Junkers built several aircraft (some of them quite successful) combining the cantilever wing and all-metal construction long before these features were fashionable. As you mention, the rest of the aviation world took a while to catch up. Would it have been so - had (say) the German aero-industry not been so heavily penalised by the 1919 armistice provisions? Who can tell? In any case I think the very brief mention of Junkers here is not inappropriate to this article. Perhaps this should have greater emphasis, not only in Junkers' own article, but also the article on monoplanes?--Soundofmusicals (talk) 06:21, 20 September 2009 (UTC)
I read your reference, and it does says that Junkers was important. But it does not seem that Junkers was the sole developer of monoplanes. For example, see Traian Vuia. I've edited some and left Junkers in, but would welcome any changes you wanna make. 02:32, 21 September 2009 (UTC)

Help[edit]

"Although the presence of two wings (or three in a triplane) adds lift in comparison with a monoplane, a tailplane is as necessary as in a biplane design."


I think there is something strange in this phrase as the tailplane produce negative lift I would say "a tailplane is more necessary in a biplane design".

Why is there a picture of a Rotan plane termed 'tandem wing biplane'? Surely a plane cannot be both at once. 145.253.108.22 15:23, 9 February 2007 (UTC)

See Also Links[edit]

I do not understand why the link to the Microraptor article, which is a dinosaur, is present in the "See also" section.

I took the liberty of removing it, and adding links to the monoplane and triplane articles.--Empowered 18:47, 29 July 2006 (UTC)

The author is making incorrect conclusions about disadvantages of biplane versus monoplane. Monoplane is (about 30%)[1] less efficient aerodynamically compare to biplane. The aerodynamic advantage of biplane has been known for about 100 years. In fact the Wright brothers knew about advantages of biplane along with many other people. Ashame to the modern aviators. They are not as educated in science as people used to be 100 years ago. —Preceding unsigned comment added by 67.150.10.123 (talk) 14:56, 24 May 2008 (UTC)

Rewrite[edit]

The text of this article had become very incoherent due to sentences and paragraphs etc. being split up and shuffled. I have rearranged the text into something more closely resembling the original order - taking the opportunity to brush up the prose. Hopefully it now makes better sense.

Comments welcome! Soundofmusicals 23:39, 11 July 2007 (UTC)

The following sentance needs clarification: Excessive amounts of stagger reduce the structural benefits of the biplane layout. The proceeding portion of the article does not detail any structural benifits derived from this configuration, only aerodynamic effects. The preceding paragraph needs to include whatever information to which this comment alludes.

Needs a refix again, this is really weird stuff. - Anon —Preceding unsigned comment added by 76.108.130.36 (talk) 16:32, 29 December 2007 (UTC)

History[edit]

This had become bogged down a little with irrelevancies like wing warping vs. ailerons - I have basically rewritten it! The point is that biplanes were common because "braced" monoplane wings (as opposed to cantilever ones) tended to produce aeroplanes that were almost uncontrollable in the "lateral" or roll sense. This was WORSE with ailerons (which is why so many early monoplanes used wing warping). The point was that a control surface like an aileron becomes a "tab" and acts in the opposite sense on a wing that is liable to distortion by load or aerodynamic forces. Not nice.Soundofmusicals (talk) 22:30, 28 December 2007 (UTC)

Suggestions for improvement[edit]

Hi:

The rise and fall of the bi-plane design may make a good measure of the earliest phase of heavier than air flight. Advancements in engineering design and materials choice, aeronautical science and powerplants each contributed to the end of the bi-plane period. I think some reorganizing may make this a very satisfying read. When did the bi-plane period have its sunset? When was its zenith? Ultimately, the design was doomed but how did the design peak? —Preceding unsigned comment added by 69.157.185.24 (talk) 04:37, 8 September 2008 (UTC)

Suggestion: The article has missed the double-decker of Otto Lilienthal, a true biplane. And the tail-less biplane gliders and powered craft seem to be missing. Definitive theory concerning stagger and separation would seem to be appropriate. Extreme separation of wings? Stacked power parafoil kites are proably part of this biplane concern.

"Bay" terminology[edit]

Just for one example, the Macchi M.71 is mentioned as a single-bay biplane. The Fairey Fremantle otoh is a two-bay biplane. Could anyone explain what this bay terminology indicates? Also, I'm unlikely to be the only one to wonder, so a little mention in the article would be a welcome addition. Thanks in advance, Jan olieslagers (talk) 04:34, 9 September 2010 (UTC)

It is explained at Interplane strut#Bays. Is it not linked or mentioned in this article? I thought it was, if not it needs fixing. Cheers Nimbus (Cumulus nimbus floats by) 08:46, 9 September 2010 (UTC)
To avoid overlinking, would it not ne better to include a short explanation of the term in this article.TheLongTone (talk) 07:00, 4 June 2011 (UTC)
