Inline Engine (aviation)
In aviation, an inline engine is a reciprocating engine with banks of cylinders, one behind another, rather than rows of cylinders, with each bank having any number of cylinders, although more than six is uncommon. The major reciprocating-engine alternative configuration is the radial engine, where the cylinders are placed in a circular or "star" arrangement. The term "inline" is used somewhat differently for aircraft engines than automotive engines. For automotive engines, the term ‘inline’ refers only to straight engines (those with a single bank of cylinders). But for aircraft, ‘inline’ can also refer to engines which are not of the straight configuration, such as V, H, or horizontally opposed. Inline engine configurations ;Straight: Engines with a single bank of cylinders which can be arranged at any angle but typically upright or inverted, (e.g. upright ADC Cirrus, inverted de Havilland Gipsy Major). ; V:Engines with two banks of cylinders with less than 180° betwe ...

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albatros L 73
__NOTOC__ The Albatros L 73 was a German twin-engined biplane airliner of the 1920s. Of conventional configuration, it featured a streamlined, boat-like fuselage and engine nacelles. All four manufactured aircraft of that type were operated by Deutsche Luft Hansa, one of which (''Brandenburg'', ''D-961'') crashed near Babekuhl on 28 May 1928.

Albatros L 75
__NOTOC__ The Albatros L 75 ''Ass'' (German: "Ace") was a German trainer biplane of the 1920s. Of conventional configuration, it seated the pilot and instructor in separate, open cockpits. The wings were single-bay, equal-span, and had a slight stagger. Production continued after Albatros was absorbed by Focke-Wulf.

BMW IV
The BMW IV was a six-cylinder, water-cooled inline aircraft engine built in Germany in the 1920s. Power was in the 180 kW (250 hp) range. World record On 17 June 1919 Franz Zeno Diemer flew a DFW F37, powered by a BMW IV engine to an unofficial world record height of from Oberwiesenfeld, reaching that altitude in 89 minutes. Diemer stated at the time, "I could have gone much higher, but I didn't have enough oxygen."

Water-cooled
Cooling tower and water discharge of a nuclear power plant Water cooling is a method of heat removal from components and industrial equipment. Evaporative cooling using water is often more efficient than air cooling. Water is inexpensive and non-toxic; however, it can contain impurities and cause corrosion. Water cooling is commonly used for cooling automobile internal combustion engines and power stations. Water coolers utilising convective heat transfer are used inside high-end personal computers to lower the temperature of CPUs. Other uses include the cooling of lubricant oil in pumps; for cooling purposes in heat exchangers; for cooling buildings in HVAC and in chillers. Mechanism Advantages Water is inexpensive, non-toxic, and available over most of the earth's surface. Liquid cooling offers higher thermal conductivity than air cooling. Water has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Rohrbach Ro VII Robbe II
The Rohrbach Ro VII Robbe ( en, Seal) was an all-metal, twin engine flying boat built in Germany in the 1920s. It could be adapted to commercial or military rôles. Design and development As the full company name (Rohrbach Metall-Flugzeugbau) makes clear, all Rohrbach aircraft were all-metal, including their duralumin skinning. The Robbe was a monoplane with a high wing described at the time as a semi-cantilever structure, meaning that there were no rigid wing struts but that it retained external bracing with flying wires to the wings from the lower fuselage. The wings were mounted with 5° of dihedral. In plan they were straight tapered, with unswept leading edges and blunt tips. Internally the wings were built around single box spars, assisted by leading edge and trailing edge boxes. The edge boxes also served as fuel tanks. At this time there were still doubts about the repairability of metal aircraft, so the Robbe's two-part wing was designed to be easy to inspect interna ...
