Blimps
A non-rigid airship, commonly called a blimp ( /blɪmp/), is an airship (dirigible) without an internal structural framework or a keel. Unlike semi-rigid and rigid airships (e.g. Zeppelins), blimps rely on the pressure of their lifting gas (usually helium, rather than flammable hydrogen) and the strength of the envelope to maintain their shape. Blimps are known for their use in advertising, surveillance, and observation due to their maneuverability, slow speeds and steady flight capabilities. Principle Since blimps keep their shape with internal overpressure, typically the only solid parts are the passenger car (gondola) and the tail fins. A non-rigid airship that uses heated air instead of a light gas (such as helium) as a lifting medium is called a hot-air airship (sometimes there are battens near the bow, which assist with higher forces there from a mooring attachment or from the greater aerodynamic pressures there). Volume changes of the lifting gas due to temperature c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airship
An airship, dirigible balloon or dirigible is a type of aerostat (lighter-than-air) aircraft that can navigate through the air flying powered aircraft, under its own power. Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift (physics), lift needed to stay airborne. In early dirigibles, the lifting gas used was hydrogen gas, hydrogen, due to its high lifting capacity and ready availability, but the inherent flammability led to several fatal accidents that rendered hydrogen airships obsolete. The alternative lifting gas, helium gas is not flammable, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airship usage in North America. Most airships built since the 1960s have used helium, though some have used thermal airship, hot air. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells.

SS Class Blimp
SS (''Submarine Scout'' or ''Sea Scout'') class airships were simple, cheap and easily assembled small non-rigid airships or "blimps" that were developed as a matter of some urgency to counter the German U-boat threat to British shipping during World War I. A secondary purpose was to detect and destroy mines. The class proved to be versatile and effective, with a total of 158 being built in several versions.SS class airship. Airship Heritage Trust. Retrieved on 18 March 2009. Requirement Soon after the outbreak of World War I, the threat to British shipping from German submarines became increasingly apparent, with numerous losses occurring during October and November 1914.

Zeppelin
A Zeppelin is a type of rigid airship named after the German inventor 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 German Empire, 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 forms of 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.

Hydrogen
Hydrogen is a chemical element; it has chemical symbol, symbol H and atomic number 1. It is the lightest and abundance of the chemical elements, most abundant chemical element in the universe, constituting about 75% of all baryon, normal matter. Under standard conditions, hydrogen is a gas of diatomic molecules with the chemical formula, formula , called dihydrogen, or sometimes hydrogen gas, molecular hydrogen, or simply hydrogen. Dihydrogen is colorless, odorless, non-toxic, and highly combustible. Stars, including the Sun, mainly consist of hydrogen in a plasma state, while on Earth, hydrogen is found as the gas (dihydrogen) and in molecular forms, such as in water and organic compounds. The most common isotope of hydrogen (H) consists of one proton, one electron, and no neutrons. Hydrogen gas was first produced artificially in the 17th century by the reaction of acids with metals. Henry Cavendish, in 1766–1781, identified hydrogen gas as a distinct substance and discovere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Goodyear Blimp (2722137105)
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee' ...

Buoyancy Compensator (aviation)
The static buoyancy of airships in flight is not constant. It is therefore necessary to control the altitude of an airship by controlling its buoyancy: buoyancy compensation. Changes which have an effect on buoyancy * Changes in air temperature (and thus the density of air) * Changes in lifting gas temperature (for example, the heating of the hull by the sun). * Accumulation of additional ballast (for example, precipitation or icing on the envelope) * Changes in ballast (for example, during a flight maneuver or the dropping of ballast) * Changes in weight of fuel on board, due to fuel consumption. This was a challenge especially in the large historic airships like the Zeppelins. For example, on a flight from Friedrichshafen to Lakehurst, the rigid airship USS Los Angeles (ZR-3), LZ 126, built in 1923-24, used 23,000 kg gasoline and 1300 kg of oil (an average consumption of 290 kg/100 km). During the landing the airship had to release approximately 24,000 cubi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

RNAS Capel
RNAS Capel (later RAF Folkestone) was a First World War airship station near Folkestone, Kent. History When Germany declared in February 1915 that it would commence unrestricted submarine warfare, the Royal Navy responded with the building of airship stations around the coast. Being close to the Dover Straits the open fields east of Capel-le-Ferne were seen as ideal location for a base and work began in April 1915. Although not entirely completed, the base was officially opened on 8 May 1915, under the command of Lt. A.D. Cunningham. The first airship for Capel was to have been SS-1 the first of a new sea scout class of non-rigid airships, on delivery to Capel from RNAS Kingsnorth on 7 May it hit telegraph wires and was destroyed. Despite the accident, more sea scouts were soon delivered to Capel. Airship production Following the successful repair to SS-10 at Capel production of the airships moved from Kingsnorth to Capel, although by 1916 production had moved again to Vicker ...

Victor Goddard
Air Marshal Sir Robert Victor Goddard, (6 February 1897 – 21 January 1987) was a senior commander in the Royal Air Force during the Second World War. Goddard is perhaps best known for his interest in paranormal phenomena; he claimed to have witnessed a clairvoyant incident in 1946 on which the feature film ''The Night My Number Came Up'' (1955) was later based. Early life Goddard was born at Wembley the son of Dr Charles Goddard. After attending St George's School, Harpenden, he went to the Royal Naval Colleges at Royal Naval College, Osborne#Naval College, Osborne and Britannia Royal Naval College, Dartmouth. He served as a midshipman in the first year of the First World War and in 1915 joined the Royal Naval Air Service. At this time he met his lifelong friend Barnes Wallis. His duties included patrolling for submarines in Airship, dirigibles; he claims that during this period he was responsible for the creation of the term "Blimp#Etymology, blimp".

Imperial War Museum
The Imperial War Museum (IWM), currently branded "Imperial War Museums", is a British national museum. It is headquartered in London, with five branches in England. Founded as the Imperial War Museum in 1917, it was intended to record the civil and military war effort and sacrifice of the United Kingdom and its Empire during the First World War. The museum's remit has since expanded to include all conflicts in which British or Commonwealth forces have been involved since 1914. As of 2012, the museum aims "to provide for, and to encourage, the study and understanding of the history of modern war and 'wartime experience'." Originally housed in the Crystal Palace at Sydenham Hill, the museum opened to the public in 1920. In 1924, it moved to space in the Imperial Institute in South Kensington and in 1936 it acquired a permanent home at the former Bethlem Royal Hospital in Southwark, which serves as its headquarters. The outbreak of the Second World War saw the museum expand bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
