USS Los Angeles (ZR-3)
USS ''Los Angeles'' was a rigid airship, designated ZR-3, which was built in 1923–1924 by the Luftschiffbau Zeppelin, Zeppelin company in Friedrichshafen, Germany, as war reparations. She was delivered to the United States Navy in October 1924 and after being used mainly for experimental work, particularly in the development of the American parasite fighter program, was decommissioned in 1932. Design The second of USS Los Angeles, four vessels to carry the name USS ''Los Angeles'', the airship was built for the United States Navy as a replacement for the Zeppelins that had been assigned to the United States as war reparations following World War I, and had been sabotaged by their crews in 1919. Under the terms of the Treaty of Versailles Luftschiffbau Zeppelin were not permitted to build military airships. In consequence ''Los Angeles'', which had the Zeppelin works number LZ 126, was built as a passenger airship, although the treaty limitation on the permissible volume ...

Mooring Mast
A mooring mast, or mooring tower, is a structure designed to allow for the docking of an airship outside of an airship hangar or similar structure. More specifically, a mooring mast is a mast or tower that contains a fitting on its top that allows for the bow of the airship to attach its mooring line to the structure. When it is not necessary or convenient to put an airship into its hangar (or shed) between flights, airships can be moored on the surface of land or water, in the air to one or more wires, or to a mooring mast. After their development mooring masts became the standard approach to mooring airships as considerable manhandling was avoided.Williams, T, 2009 (Reissue), "Airship Pilot No. 28", Darcy Press, UK, Mast types Airship mooring masts can be broadly divided into fixed high masts and fixed or mobile low (or ‘stub’) masts. In the 1920s and 1930s masts were built in many countries. At least two were mounted on ships. Without doubt the tallest mooring ma ...

Edwin Taylor Pollock
Edwin Taylor Pollock (October 25, 1870June 4, 1943) was a career Officer (armed forces), officer in the United States Navy, serving in the Spanish–American War and in World War I. He was later promoted to the rank of Captain (naval), captain. As a young Ensign (rank), ensign, Pollock served aboard during the Spanish–American War. After the war, he rose through the ranks, served on several ships, and did important research into wireless communication. In 1917, less than a week before the United States entered World War I, he won a race against a fellow officer to receive the United States Virgin Islands, U.S. Virgin Islands from Denmark, and served as the territory's first acting governor. During the war, he was promoted to captain and a vessel under his command transported 60,000 American soldiers to France, for which he was awarded a Navy Cross (United States), Navy Cross. Afterward, he was made the eighth Naval Governor of American Samoa and then the superintendent of the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Eclipse Of January 24, 1925
A total solar eclipse occurred at the Moon's descending node of orbit on Saturday, January 24, 1925, with a magnitude of 1.0304. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Occurring about 1.1 days after perigee (on January 23, 1925, at 13:30 UTC), the Moon's apparent diameter was larger. Totality was visible from southwestern and southeastern Ontario in Canada (including Toronto and Niagara Falls), Minnesota, Wisconsin, Michigan, Pennsylvania, New York (including the northern part of New York City), New Jersey, Connecticut, Rhode Island, and Massachusetts. A partial eclipse was vis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Helium
Helium (from ) is a chemical element; it has chemical symbol, symbol He and atomic number 2. It is a colorless, odorless, non-toxic, inert gas, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the Chemical element, elements, and it does not have a melting point at standard pressures. It is the second-lightest and second-most Abundance of the chemical elements, abundant element in the observable universe, after hydrogen. It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and Jupiter, because of the very high nuclear binding energy (per nucleon) of helium-4 with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, ...

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] |
Naval Support Facility Anacostia
Naval Support Facility (NSF) Anacostia is a United States Naval Base in Washington, D.C., close to where the Anacostia River joins the Potomac River. On 1 October 2010 the base was conjoined with the adjacent Bolling Air Force Base to form the Joint Base Anacostia–Bolling in accordance with congressional legislation implementing the recommendations of the 2005 Base Realignment and Closure Commission. NSF Anacostia fell under the command of Naval Support Activity Washington. History Prior to European colonization, the area where the Naval Support Facility Anacostia was located was inhabited by the Nacotchtank, an Algonquian people. The largest village of the Nacotchtank was located just north of Bolling Air Force Base, south of Anacostia Park. Two ossuaries (burial grounds) have been discovered at Bolling Air Force Base. Other Nacotchtank archaeological sites have been found at Giesboro Point on the Potomac River, close to where the Naval Support Facility was once l ...
