LZ 4
The Zeppelin ''LZ 4'' was a German experimental airship constructed under the direction of Ferdinand von Zeppelin. First flown on 20 June 1908, it made a series of successful flights including a 12-hour flight over Switzerland. It was destroyed when it caught fire after landing to carry out engine repairs during a projected 24-hour endurance trial. This disaster proved fortunate for Zeppelin: donations by the German public raised 6.5 million marks, so guaranteeing the future of his development of airships. Background The successful flights of '' LZ 3'' in 1906 had produced a change in the official attitude to Count Zeppelin's work, and a grant of 500,000 marks had been voted by the Reichstag. However, a condition of purchase by the government was the completion of a 24-hour trial flight. This was beyond the capabilities of ''LZ 3'', so work was started on a larger airship with greater fuel capacity. Design and development Construction of ''LZ 4'' was started in Nov ...

Ludwig Dürr
Ludwig Dürr (4 June 1878 in Stuttgart – 1 January 1956 in Friedrichshafen) was a German airship designer. Life and career After completing training as a mechanic, Dürr continued his training at the Königliche Baugewerkschule (Royal School of Engineering). In 1898 he entered the German Navy, but was discharged at the end of the year. Beginning in 1899, Dürr worked for Ferdinand von Zeppelin. After assisting in the construction of the first zeppelin airship, the LZ 1, he himself began to construct airships and lightweight construction parts. All of the following zeppelin designs were Dürr's. He often flew on board his designs, at the elevator control wheel, including the maiden flight of Zeppelin LZ 5 to Bitterfeld and back. On 31 May 1909, Dürr was still at the elevator controls after the 37 hour flight, when the nose of the ship crashed into a pear tree near Göppingen. He was employed by the Zeppelin company until its dissolution in 1945, from 1915 on as technical d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerodynamic Drag
In fluid dynamics, drag (sometimes called air resistance, a type of friction, or fluid resistance, another type of friction or fluid friction) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag force depends on velocity. Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Even though the ultimate cause of drag is viscous friction, turbulent drag is independent of viscosity. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zeppelins
A Zeppelin is a type of rigid airship named after the German inventor Count Ferdinand von Zeppelin () who pioneered rigid airship development at the beginning of the 20th century. Zeppelin's notions were first formulated in 1874Eckener 1938, pp. 155–157. and developed in detail in 1893.Dooley 2004, p. A.187. They were patented in Germany in 1895 and in the United States in 1899. After the outstanding success of the Zeppelin design, the word ''zeppelin'' came to be commonly used to refer to all rigid airships. Zeppelins were first flown commercially in 1910 by Deutsche Luftschiffahrts-AG (DELAG), the world's first airline in revenue service. By mid-1914, DELAG had carried over 10,000 fare-paying passengers on over 1,500 flights. During World War I, the German military made extensive use of Zeppelins German strategic bombing during World War I, as bombers and aerial reconnaissance in World War I, as scouts, resulting in over 500 deaths in bombing raids in Britain.

List Of Zeppelins
This is a complete list of Zeppelins constructed by the German Zeppelin companies from 1900 until 1938. Other rigid airships that are also sometimes referred to as zeppelins but not built by Zeppelin are not included. The Zeppelin company based in Friedrichshafen, Germany, numbered their aircraft ''LZ 1/2/ ...'', with ''LZ'' standing for "Luftschiff [airship] Zeppelin". Additionally, craft used for civilian purposes were named, whereas military airships were usually given "tactical numbers": * The German Army (German Empire), ''Deutsches Heer'' called its first Zeppelins ''Z I/II/ ... /XI/XII''. During World War I they switched to using ''LZ'' numbers, later adding 30 to obscure the total production. * The Imperial German Navy, ''Kaiserliche Marine'''s Zeppelins were labelled ''L 1/2/ ...''. Since 1997, airships of the new type Zeppelin NT have been flying. They are not included here, as they are Semi-rigid airship, not rigid airships and do not represent a cont ...

Daimler Motoren Gesellschaft
Daimler-Motoren-Gesellschaft (abbreviated as DMG, also known as ''Daimler Motors Corporation'') was a German engineering company and later automobile manufacturer, in operation from 1890 until 1926. Founded by Gottlieb Daimler (1834–1900) and Wilhelm Maybach (1846–1929), it was based first in Cannstatt (today Bad Cannstatt, a city district of Stuttgart). Daimler died in 1900, and their business moved in 1903 to Stuttgart-Untertürkheim after the original factory was destroyed by fire, and again to Berlin in 1922. Other factories were located in Marienfelde (near Berlin) and Sindelfingen (next to Stuttgart). The enterprise began to produce petrol engines but after the success of a small number of race cars built on contract by Wilhelm Maybach for Emil Jellinek, it began to produce the '' Mercedes'' model of 1902. After this automobile production expanded to become ''DMG'''s main product, and it built several models. Because of the post World War One German economic crisis, '' ...

Static Electricity
Static electricity is an imbalance of electric charges within or on the surface of a material or between materials. The charge remains until it is able to move away by means of an electric current or electrical discharge. Static electricity is named in contrast with current electricity, where the electric charge flows through an electrical conductor or space, and transmits energy. A static electric charge can be created whenever two surfaces contact and have worn and separated, and at least one of the surfaces has a high resistance to electric current (and is therefore an electrical insulator). The effects of static electricity are familiar to most people because people can feel, hear, and even see the spark as the excess charge is neutralized when brought close to a large electrical conductor (for example, a path to ground), or a region with an excess charge of the opposite polarity (positive or negative). The familiar phenomenon of a static shockmore specifically, an electros ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Echterdingen
Leinfelden-Echterdingen ( Swabian: ''Laefälda-Ächdordeng'') is a town in the district of Esslingen, in Baden-Württemberg, Germany. It is located approximately 10 km south of Stuttgart, near the Stuttgart Airport and directly adjacent to the newly built Stuttgart Trade Fair.

Oppenheim
Oppenheim () is a town in the Mainz-Bingen district of Rhineland-Palatinate, Germany. The town is a well-known wine center, being the home of the German Winegrowing Museum, and is particularly known for the wines from the Oppenheimer Krötenbrunnen vineyards. Geography Location The town lies on the Upper Rhine in Rhenish Hesse between Mainz and Worms. It is the seat of the Verbandsgemeinde (special administrative district). History In 765, the first documented mention of the Frankish village was recorded in the Lorsch Codex, in connection with an endowment by Charlemagne to the Lorsch Abbey. Further portions of Oppenheim were added to the endowment in 774. In 1008, Oppenheim was granted market rights. In October 1076 Oppenheim gained special importance in the Investiture Controversy. At the princely session of Trebur and Oppenheim, the princes called on King Henry IV to undertake the "Walk to Canossa". After Oppenheim was returned to the Empire in 1147, it became a Free ...
