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 La ...

Germany
Germany, officially the Federal Republic of Germany, is a country in Central Europe. It lies between the Baltic Sea and the North Sea to the north and the Alps to the south. Its sixteen States of Germany, constituent states have a total population of over 84 million in an area of , making it the most populous member state of the European Union. It 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 Capital of Germany, nation's capital and List of cities in Germany by population, most populous city is Berlin and its main financial centre is Frankfurt; the largest urban area is the Ruhr. Settlement in the territory of modern Germany began in the Lower Paleolithic, with various tribes inhabiting it from the Neolithic onward, chiefly the Celts.

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 * The French aircraft designer and manufacturer Édouard Nieuport makes some brief straight-line flights in his first aircraft, a small monoplane powered by a Darracq engine. Opdycke, Leonard E., ''French Aeroplanes Before The Great War'', Atglen, Pennsylvania: Achiffer, 1999, , p. 189. * Fort Omaha Balloon School becomes the first United States Army school for balloon observers. * The Austro-Hungarian Navy sends 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 wings. 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 slowe ...

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 struts, which act in Compression (physics), compression or Tension (physics), 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 (aerodynamics), 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 aeroplanes, including the monoplanes and biplanes, which were then equally common. Today, bracing in the form of lift struts is still used for some light com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wing-warping
Wing warping was an early system for lateral (roll) control of a fixed-wing aircraft or kite. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It receives about 1.5 million visitors per year. The museum was founded on 28 June 1903, at a meeting of the Verein Deutscher Ingenieure, 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 ...
