Grade Monoplane
The Grade monoplane was a single-seat aircraft constructed by Hans Grade in 1909. It was the first successful heavier-than-air aircraft produced in Germany, and around 80 were eventually built. Design and development The aircraft was a high-wing monoplane, with the pilot sitting below the wing. A pair of inverted V struts formed the fabric-covered cabane structure which carried the upper bracing wires: the front struts were continued below the wing, with the forward struts bearing the mainwheels. An elongated cruciform tail unit was attached to the end of a single boom by a universal joint immediately behind the single tailwheel. Lateral control was effected by wing-warping. It was powered by a 12 kW (18 hp) two-stroke air-cooled V-4 engine, also built by Grade, which drove a two-bladed aluminium bladed propeller. Operational history The aircraft was first flown on 17 August 1909 A series of longer flights were made in September, and on October 30 Grade won the Lan ...

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] |
Hans Grade
Hans Grade (May 17, 1879 – October 22, 1946) was a German aviation pioneer. Hans Grade was born in Köslin, Pomerania. On 28 October 1908 he successfully conducted the first motor-flight over German soil in a motorised triplane aircraft of his own construction at Magdeburg. A year later, on 30 October 1909, flying a new monoplane design he won the 40.000 Reichsmark "Lanz-Preis der Lufte", for the first German to fly a flat "8" in a German aircraft with German engine around two pylons 1000 meters apart. In 1910 he established the first aviation school in Germany. A Grade monoplane carried Germany's first air mail, when pilot Pentz made a flight from Bork to Bruck in February 1912 with a small sack of mail in his lap. Although successful, Grade monoplanes did not become as famous as many contemporary European designs, and for this reason comparatively few were built. In 1921 he established an automobile company called " Grade Automobilwerke AG", which produced small, 2 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1909 In Aviation
This is a list of aviation-related events from 1909: Events * Fort Omaha Balloon School becomes the first United States Army school for balloon observers. * The Austro-Hungarian Navy sends Commissioned officer, officers abroad for flight training. * In the book ''L'Aviation Militaire'' ("Military Aviation"), Clément Ader writes ''...an aircraft carrier will become indispensable. Such ships will be very differently constructed from anything in existence today. To start with, the deck will have been cleared of any obstacles: it will be a flat area, as wide as possible, not conforming to the lines of the hull, and will resemble a landing strip. The speed of this ship will have to be at least as great as that of cruisers or even greater...Servicing the aircraft will have to be done below this deck...Access to this lower deck will be by means of a lift long enough and wide enough to take an aircraft with its wings folded...Along the sides will be the workshops of the mechanics res ...

Monoplane
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple planes. A monoplane has inherently the highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. Characteristics Support and weight The inherent efficiency of the monoplane is best achieved in the cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower a ...

Cabane Strut
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplane, including the monoplanes and biplanes which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more impo ...

Wing-warping
Wing warping was an early system for lateral (roll) control of a fixed-wing aircraft. The technique, used and patented by the Wright brothers, consisted of a system of pulleys and cables to twist the trailing edges of the wings in opposite directions. In many respects, this approach is similar to that used to trim the performance of a paper airplane by curling the paper at the back of its wings. Description In 1900, Wilbur Wright wrote, "...my observations of the flight of birds convince me that birds use more positive and energetic methods of regaining equilibrium than that of shifting the center of gravity...they regain their lateral balance...by a torsion of the tips of the wings. If the rear edge of the right wing tip is twisted upward and the left downward the bird becomes an animated windmill and instantly begins to turn, a line from its head to its tail being the axis." After Wilbur demonstrated the method, Orville noted, "From this it was apparent that the wings of a mac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heliopolis (Cairo Suburb)
Heliopolis ( arz, مصر الجديده, ', , "New Egypt") was a suburb outside Cairo, Egypt, which has since merged with Cairo as a district of the city and is one of the more affluent areas of Cairo. Named for the ancient Egyptian city of Heliopolis (ancient Egypt), Heliopolis to which it lies adjacent, modern Heliopolis was established in 1905 by the Cairo Electric Railways & Heliopolis Oases Company, Heliopolis Oasis Company headed by the Belgians, Belgian industrialist Édouard Empain and by Boghos Nubar, son of the Egyptian Prime Minister Nubar Pasha. It is the location of the Cairo International Airport. The population of Heliopolis is estimated at some 142,968 individuals (2016). History Baron Empain, a well-known amateur Egyptologist and prominent Belgian entrepreneur, arrived in Egypt in January 1904, intending to rescue one of his Belgian wife's development projects: the construction of a railway line linking Al-Matariyyah to Port Said.

Deutsches Museum
The Deutsches Museum (''German Museum'', officially (English: ''German Museum of Masterpieces of Science and Technology'')) in Munich, Germany, is the world's largest museum of science and technology, with about 28,000 exhibited objects from 50 fields of science and technology. It receives about 1.5 million visitors per year. The museum was founded on 28 June 1903, at a meeting of the Association of German Engineers (VDI) as an initiative of Oskar von Miller. It is the largest museum in Munich. For a period of time the museum was also used to host pop and rock concerts including The Who, Jimi Hendrix and Elton John. Museumsinsel The main site of the Deutsches Museum is a small island in the Isar river, which had been used for rafting wood since the Middle Ages. The island did not have any buildings before 1772 because it was regularly flooded prior to the building of the Sylvensteinspeicher. In 1772 the Isar barracks were built on the island and, after the flooding of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piston Engine
A reciprocating engine, also often known as a piston engine, is typically a heat engine that uses one or more reciprocating pistons to convert high temperature and high pressure into a rotating motion. This article describes the common features of all types. The main types are: the internal combustion engine, used extensively in motor vehicles; the steam engine, the mainstay of the Industrial Revolution; and the Stirling engine for niche applications. Internal combustion engines are further classified in two ways: either a spark-ignition (SI) engine, where the spark plug initiates the combustion; or a compression-ignition (CI) engine, where the air within the cylinder is compressed, thus heating it, so that the heated air ignites fuel that is injected then or earlier.''Thermodynamics: An Engineering Approach'' by Yunus A. Cengal and Michael A. Boles Common features in all types There may be one or more pistons. Each piston is inside a cylinder, into which a gas is intro ...
