Parseval-Sigsfeld Kite Balloon
The Parseval-Sigsfeld kite balloon (German: ''Parseval-Sigsfeld Drachenballon'') was a type of non-rigid military observation balloon, designed in 1898 by August von Parseval and . Its aerodynamic shape and the rear air capsule ensured a stable position owing to the force of the wind, similar to the way in which kites are stabilized; for this reason it was known as the kite balloon (German: ''Drachenballon''). This aircraft was widely used as the main observation balloon type by the Central Powers during World War I. Design German airship factory owner, August von Parseval, and German military officer, Hans Bartsch von Sigsfeld, had been experimenting with different balloon shapes since 1893, previously using spherical shapes that had proved to be unstable in windy weather. Around 1898 they constructed a balloon with an elongated shape, equipped with stabilizers, which were later replaced by suitably shaped air chambers. Under the pressure of the wind (the permissible s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caquot Kite Balloon
Caquot kite balloon (in French language, French ''Caquot Captif'') was a type of non-rigid military observation balloon, designed in 1915 by Albert Caquot. The type became widely used by Allied forces in World War I , World War I warfare for multiple observation or naval defence uses and later also as a Anti-aircraft warfare, anti-aircraft barrage balloon. Design At the beginning of World War I French Army headquarters quickly realized a need of observation balloon units, which has been dismantled in 1912. German army used their successful Parseval-Sigsfeld kite balloons (or ''Drachen'') in large quantities, so the first French-produced pieces were produced as a copies of a German original. Being mobilized on 1 August 1914 as a commander of the 21st company of balloonists, French officer Albert Caquot made some aerial observations in a spherical "Fleurus" type balloon, a type dating from 1880s. To balance a balloon dangling even in light winds Caquot designed a new balloon type ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rzeczpospolita
() is a traditional Polish term for a political community founded for the common good.

Winogrady
Winogrady is a part of the Stare Miasto district of the city of Poznań in western Poland. It is situated north of the ''Cytadela'' park (the former Poznań citadel). The name refers to the vineyards which formerly existed in the area – historically there were two villages there called Winiary (although "Winiary" today refers to a neighbourhood in Jeżyce district, to which the inhabitants were moved when the citadel fortifications were built in the 1830s). The southern part of Winogrady, between the streets ''ul. Winogrady'' and ''ul. Słowiańska'', consists mainly of houses, although there are also some apartment blocks (including the "Batman" development, named for its black colour) and student halls of residence.

Austro-Hungarian Army
The Austro-Hungarian Army, also known as the Imperial and Royal Army,; was the principal ground force of Austria-Hungary from 1867 to 1918. It consisted of three organisations: the Common Army (, recruited from all parts of Austria-Hungary), the Imperial-Royal Landwehr (recruited from Cisleithania) and the Royal Hungarian Honvéd (recruited from Transleithania). In the wake of fighting between the Austrian Empire and the Kingdom of Hungary and the subsequent two decades of uneasy co-existence, Hungarian troops served either in ethnically mixed units or were stationed away from Hungarian regions. With the Austro-Hungarian Compromise of 1867, the Austro-Hungarian Army was brought into being. It existed until the disestablishment of Austria-Hungary in 1918 following the end of World War I. Common Army units were generally poorly trained and had very limited access to new equipment, because the governments of the Austrian and Hungarian parts of the empire often preferred to ge ...

Ballonet
A ballonet is an inflatable bag inside the outer envelope of an airship which, when inflated, reduces the volume available for the lifting gas, making it more dense. Because air is also denser than the lifting gas, inflating the ballonet reduces the overall lift, while deflating it increases lift. In this way, the ballonet can be used to adjust the lift as required. Ballonets may typically be used in non-rigid or semi-rigid airships, commonly with multiple ballonets located both fore and aft to maintain balance and to control the pitch of the airship. The image illustrates the principle of a balloon within a balloon. The outer balloon represents the airship's outer envelope or gasbag, while the red inner balloon represents the ballonet. In an airship the ballonet would be much smaller relative to the size of the gasbag; for example, in the French airship Lebaudy Patrie the volume of the ballonet was approximately one-fifth that of the envelope. History The ballonet was fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phallic
A phallus (: phalli or phalluses) is a penis (especially when erect), an object that resembles a penis, or a mimetic image of an erect penis. In art history, a figure with an erect penis is described as ''ithyphallic''. Any object that symbolically—or, more precisely, iconically—resembles a penis may also be referred to as a phallus; however, such objects are more often referred to as being phallic (as in "phallic symbol"). Such symbols often represent fertility and cultural implications that are associated with the male sexual organ, as well as the male orgasm. Etymology The term is a loanword from Latin ''phallus'', itself borrowed from Greek (''phallos''), which is ultimately a derivation from the Proto-Indo-European root *''bʰel''- "to inflate, swell". Compare with Old Norse (and modern Icelandic) ''boli'', "bull", Old English ''bulluc'', "bullock", Greek , "whale". Archaeology The Hohle phallus, a 28,000-year-old siltstone phallus discovered in the Hohle Fels c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
