  Biplane - Wikipedia, the free encyclopedia
A variation on the biplane was the sesquiplane, where the (usually) lower wing was significantly smaller than the other, either in span, chord, or both.
The Stearman is particularly associated with stunt flying with wing-walkers.
The vast majority of biplane designs have been fitted with reciprocating engines of comparatively low power; exceptions include the Antonov An-3 and WSK-Mielec M-15 Belphegor, fitted with turboprop and turbofan engines, respectively.

 3 Sea Bees - Nieuport17-C1 Documentation
This half wing or Sesquiplane layout was the Newport trademark until their type 28 in early 1918.
All the Nieuport sesquiplane designs followed French constructional methods in vogue during the early part of W.W.I. The fuselage was a rectangular section girder, diagonally braced with wire, with steel plate socket joints and wiring plates.
Forward, the wooden longerons were of ash changing in the rear fuselage aft of the cockpit to spruce, which was also used for the vertical struts and cross-members.

 Eduard's 1/48 Albatros D.III(OAW)   (Site not responding. Last check: 2007-10-12)
The agile Nieuport was thought to owe its flying characteristics to the sesquiplane layout, and Idflieg, the command of the German Air Service, required that all German aircraft manufacturers present sesquiplanes for possible orders.
Following Idflieg's orders, Albatros took their relatively-heavy biplane and adapted it for the sesquiplane layout, which was not really suited for the kind of fighter Albatros had created; in fact, the sesquiplane layout would prove to be an aerodynamic dead-end, suited only for lightly-loaded designs like the Nieuport.
Had enough been known about the laws of aerodynamics to avoid the sesquiplane trap, it would have been an even better airplane than it was.

 Albatros D.III (OAW) Eduard 1/48 by Tom Cleaver
The German air force command had decided that if the Nieuport sesquiplane was a good fighter, all good fighters should be sesquiplanes, a logical syllogisim that did not stand up in the world of combat.
In fact, the sesquiplane design was very limited in applicability, and was far more suited to a low-powered, lightly-loaded type like the Nieuport than it was to the high-powered and much heavier Albatros.
Had the Albatroswerke designers stuck to their guns and kept the airplane a biplane, as it was in its D.I and D.II incarnations, the airplane would have been a far better fighter.

 Albatros DIII, why the sesquiplane wing? [Archive] - The Aerodrome Forum
The advantage of the early Albatros DI and DII was they had enough horsepower to bear the weight of 2 machineguns without hampering their perfomance.
Not only downwards, since there's not so much wing getting in the way, but it must be advantageous to not have your vision blocked by a cage of struts and wires as in the SPAD or to a lesser degree in all other paralell strut planes.
From what I have read the sesquiplane was the a means of providing rigid bracing to a parasol wing configuration and instead of fairing the beam a narrow wing was used to compilment the upper wing.

 Red Baron II Dynamix German Planes
It had a tendency lose its narrow lower wing in a dive, it was relatively slow, and the wing-mounted Lewis gun provided inadequate firepower.
The Nieuport 24 was an up-engined, up-gunned version of the Nieuport 17, and shared its virtues and failings, but with a top speed of 109 mph and twin Vickers machine guns, was a formidable adversary to the Albatross DIII it frequently flew against.
The Nieuport 28 was larger and heavier than the previous Nieuports, and unlike its predecessors in the line it was a biplane rather than a sesquiplane.

 What is a 1 1/2 wing a/c? [Archive] - The Aerodrome Forum
4 November 2003, 07:49 AM I don't know about an official origin for the term, but the more common term I've read to describe the same thing is, "sesquiplane." I think it's a French term.
A sesquiplane means 1 and one half wings.
Austro-Hungarian Aviatik (Berg) D.II was a "sesquiplan" - had wings with equal chord, but the lower wing was much shorter than top one.

 Eduard 1/48 Albatros D.V (Profipak)
Albatros came into the fighter game in 1916 with its D.I and D.II biplanes, which were head-and-shoulders above their competition and set the standard for a modern fighter that has stood for 86 years: fast, agile, heavily-armed and able to outperform the competition.
Not all the laws of aerodynamics were fully known at the time, and the German authorities came to believe there was something inherent in the Nieuport design that made it successful, that something being the sesquiplane design.
The Albatros design was different from the Nieuport - heavy where the Nieuport was light, and the sesquiplane was really not strong enough to perform under these kinds of loads.

 Nieu17
As a result, the Nieuport 17 was a slightly larger machine than the "Bebe," making it comparable in size to many contemporary machines.
Like the 11, the 17 had a single spar lower wing, or sesquiplane, layout.
Although providing the pilot with better vision, the design retained the weak lower wing of the 11, compelling pilots to take care when diving the machine since the spar could easily fracture.

 The Triplane Fighter Craze of 1917   (Site not responding. Last check: 2007-10-12)
As a sesquiplane (1 1/2 wings), the little Nieuport was considered a delight to fly and had been favored by many Allied aces, as well as by the American volunteers of the Lafayette Escadrille.
It had also impressed the Germans, who were emulating its sesquiplane wing arrangement before they began copying that of the Sopwith Triplane.
Called the V.1 (the "V" standing for Verspannungslos, or "without external bracing"), the new Fokker was a rotary-engine sesquiplane combining a streamlined fuselage with plywood cantilever wings.

The BE 12a had the same fuselage and tail unit as the standard BE 12, but used the sesquiplane mainplanes of the BE2e.
It is doubtfull whether the sesquiplane wings could improve the overall performance too much and in fact the Hispano-Suiza powered variant BE12b returned to the original two bay wings of BE12.
Only two contracts for the BE12a variant were given and the aeroplanes saw very limited operational use.

The French Nieuport company provided the Allied air forces with the first true fighter scout of World War 1 in the shape of the diminutive XI of 1915.
Based on the Bebe racer, built for the abandoned Gordon-Bennett Trophy of the previous year, the aircraft utilised a sesquiplane (lower wing much smaller than the upper wing) arrangement which gave the XI extreme manoeuvrability.
It was the only scout respected by the all-conquering German Fokker E-series of 1915-16, and was flown by French, British, Russian, Belgian and Italian aces.

However, the outbreak of war coincided with a developing official mistrust of the monoplane formula and the company was required to produce Voisan pusher bi-planes under licence.
Chief designer Gustave Delage, turning his attention to the developement of an original bi-plane design, evolved a new type of wing celule known as the sesquiplane.
The lower wing was much smaller in area than the upper wing and the concept combined the strength of the biplanes wire braced wing cell with the stability and good visibility of the parasol monoplane.

 Nieuport 28
(The spelling of the company name was a slight variation of the brothers' surname.) The talented designer Gustave Delage joined the firm in 1914 and was responsible for the highly successful war-time line of sesquiplane V-strut single-seat scouts, the most famous of which were the Nieuport 11 and the Nieuport 17.
In an attempt to compete with the superior performance of the Spad VII and the recently introduced Spad XIII, Nieuport explored the use of a more powerful motor than the types employed in the sesquiplane series.
The availability of a more powerful, and heavier, 160-horsepower Gnôme rotary engine prompted the decision to increase the surface area of the lower wing to compensate for the greater weight of the new powerplant, hence eliminating the typical Nieuport sesquiplane V-strut configuration.

Almost certainly built in larger numbers than any other warplane type in the period between the world wars, the Bre XIX was designed to succeed the Bre XIV that had performed so magnificently in World War I, and was still in service during the first two years of World War II.
Designed by a team under the supervision of Marcel Vuillerme, the Bre XIX was clearly inspired in basic design by its predecessor but was virtually a sesquiplane and was also a considerably more modern type in its primary structure.
The Bre XIX made its debut in Paris in 11/21 and was there revealed as a large airplane built primarily of Dural with a covering of fabric except on the forward fuselage, which was completed with Dural panels.
