H-1 (rocket Engine)
The Rocketdyne H-1 was a thrust liquid-propellant rocket engine burning LOX and RP-1. The H-1 was developed for use in the S-I and S-IB first stages of the Saturn I and Saturn IB rockets, respectively, where it was used in clusters of eight engines. After the Apollo program, surplus H-1 engines were rebranded and reworked as the Rocketdyne RS-27 engine with first usage on the Delta 2000 series in 1974. RS-27 engines continued to be used up until 1992 when the first version of the Delta II, Delta 6000, was retired. The RS-27A variant, boasting slightly upgraded performance, was also used on the later Delta II and Delta III rockets, with the former flying until 2018. History Early engines The H-1 is one of a series of engines developed from the wartime V-2 ballistic missile. During the war, North American Aviation (NAA) was given several V-2 engines to examine and convert from metric to SAE measurements. They formed their "Propulsion Division" to handle this work, later beco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Udvar-Hazy Center
The Steven F. Udvar-Hazy Center, also called the Udvar-Hazy Center, is the Smithsonian Institution, Smithsonian National Air and Space Museum (NASM)'s annex at Dulles International Airport in the Chantilly, Virginia, Chantilly area of Fairfax County, Virginia. It holds numerous exhibits, including the Space Shuttle Discovery, Space Shuttle ''Discovery'', the ''Enola Gay'', and the Boeing 367-80, the main prototype for the popular Boeing 707 airliner. The facility was made possible by a $65 million donation in October 1999 to the Smithsonian Institution by Steven F. Udvar-Házy, an immigrant from Hungary and co-founder of the International Lease Finance Corporation, an aircraft leasing corporation. The main National Air and Space Museum, NASM building, located on the National Mall in Washington, D.C., had always contained more artifacts than could be displayed, and most of the collection had been stored, unavailable to visitors, at the Paul E.

PGM-11 Redstone
The PGM-11 Redstone was the first large American ballistic missile. A short-range ballistic missile (SRBM), it was in active service with the United States Army in West Germany from June 1958 to June 1964 as part of NATO's Cold War defense of Western Europe. It was the first US missile to carry a live nuclear warhead, in the 1958 Pacific Ocean weapons test Hardtack Teak. The Redstone was a direct descendant of the German V-2 rocket, developed primarily by a team of German rocket engineers brought to the United States after World War II. The design used an upgraded engine from Rocketdyne that allowed the missile to carry the W39 and its reentry vehicle to a range of about . Redstone's prime contractor was the Chrysler Corporation. The Redstone spawned the Redstone rocket family which holds a number of firsts in the US space program, notably launching the first US astronaut. It was retired by the Army in 1964 and replaced by the solid-fueled MGM-31 Pershing. Surplus m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PGM-17 Thor
The PGM-17A Thor was the first operative ballistic missile of the United States Air Force (USAF). It was named after the Thor, Norse god of thunder. It was deployed in the United Kingdom between 1959 and September 1963 as an intermediate-range ballistic missile (IRBM) with hydrogen bomb, thermonuclear warheads. Thor was in height and in diameter. The first generation of Thor missiles were rushed into service, and design mistakes resulted in a 24% launch failure rate. The competing PGM-19 Jupiter missile saw more use, but both were quickly eclipsed by the Air Force's long range ICBM program, which could be fired from U.S. soil. By 1959, with the Atlas (rocket family), Atlas missile well on its way to operational status, both Thor and Jupiter programs became obsolete as delivery vehicles, yet continued to be built and deployed until 1963 for political reasons and to maintain aerospace industry employment. The missile's lasting legacy continued as the Thor (rocket family), Thor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PGM-19 Jupiter
The PGM-19 Jupiter was the first nuclear weapon, nuclear armed, medium-range ballistic missile (MRBM) of the United States Air Force (USAF). It was a liquid-propellant rocket using RP-1 fuel and Liquid oxygen, LOX oxidizer, with a single Rocketdyne S-3D, Rocketdyne LR79-NA (model S-3D) rocket engine producing of thrust. It was armed with the W49 nuclear warhead. The prime contractor was the Chrysler Corporation. The Jupiter was originally designed by the US Army, which was looking for a highly accurate missile designed to strike enemy states such as China and the Soviet Union. The US Navy also expressed an interest in the design as an SLBM but left the collaboration to work on their solid-fuel UGM-27 Polaris, Polaris. Jupiter retained the short, squat shape intended to fit in submarines. Development history Initial concept Jupiter traces its history ultimately to the PGM-11 Redstone missile, the US's first nuclear ballistic missile. While it was entering service, Wernher von ...

US Army
The United States Army (USA) is the primary land service branch of the United States Department of Defense. It is designated as the Army of the United States in the United States Constitution.Article II, section 2, clause 1 of the United States Constitution (1789).See alsTitle 10, Subtitle B, Chapter 301, Section 3001 It operates under the authority, direction, and control of the United States secretary of defense. It is one of the six armed forces and one of the eight uniformed services of the United States. The Army is the most senior branch in order of precedence amongst the armed services. It has its roots in the Continental Army, formed on 14 June 1775 to fight against the British for independence during the American Revolutionary War (1775–1783). After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army.Library of CongressJournals of the Continental Congress, Volume 27/ref> Th ...

SM-65 Atlas
The SM-65 Atlas was the first operational intercontinental ballistic missile (ICBM) developed by the United States and the first member of the Atlas rocket family. It was built for the U.S. Air Force by the Convair Division of General Dynamics at an assembly plant located in Kearny Mesa, San Diego. Development dates to 1946, but over the next few years the project underwent several cancellations and re-starts. The deepening of the Cold War and intelligence showing the Soviet Union was working on an ICBM design led to it becoming a crash project in late 1952, along with the creation of several other missile projects to ensure one would enter service as soon as possible. The first test launch was carried out in June 1957, which failed. The first success of the Soviet R-7 Semyorka in August gave the program new urgency, leading to the first successful Atlas A launch in December. Of the eight flights of the A model, only three were successful, but the later models demonstr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JP-5
Jet fuel or aviation turbine fuel (ATF, also abbreviated avtur) is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colorless to straw-colored in appearance. The most commonly used fuels for commercial aviation are Jet A and Jet A-1, which are produced to a standardized international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B, which is used for its enhanced cold-weather performance. Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound. Furthermore, the range of molecular mass between hydrocarbons (or different carbon numbers) is defined by the requirements for the product, such as the freezing point or smoke point. Kerosene-type jet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JP-4
JP-4, or JP4 (for "Jet Propellant") was a jet fuel, specified in 1951 by the United States Department of Defense (MIL-DTL-5624). Its NATO code is F-40. It is also known as avtag. Usage JP-4 was a 50-50 kerosene-gasoline blend. It had a lower flash point than JP-1, but was preferred because of its greater availability. It was the primary U.S. Air Force jet fuel between 1951 and 1995. MC-77 is the Swedish military equivalent of JP-4. Mixture JP-4 was a mixture of aliphatic and aromatic hydrocarbons. It was a flammable transparent liquid with clear or straw color, and a kerosene-like smell. It evaporated easily and floated on water. Although it had a low flash point (), a lit match dropped into JP-4 would not ignite the mixture. JP-4 froze at , and its maximum burning temperature was . JP-4 was a non-conductive liquid, prone to build up static electricity when being moved through pipes and tanks. As it is volatile and has a low flash point, the static discharge could cause ...

Paint Thinner
Paint thinners are diluents — solvents used to adjust the viscosity of paint, as well as similar preparations such as varnish and lacquer, by dilution. For water-based paints, such as acrylic paints, water is the primary solvent, but notably, may not always be the only solvent as there may be low level usage of other solvents to assist in ensuring a consistent paint mixture. Organic solvents labelled "paint thinner" are usually turpentine or white spirits / mineral spirits for the use of diluting oil-based paints only. These organic solvents on traditional painting materials can have harmful effects on the environment in of themselves as well as through the release of hazard substances, including lead and other additives from dissolved paint stuffs. Uses Principally, paints are either a colloidal suspension of solid pigment particles or are an emulsion of dense viscous dye gel or paste with a filler all dispersed through a lighter free-flowing liquid medium — the solve ...

Diesel Oil
Diesel fuel, also called diesel oil, heavy oil (historically) or simply diesel, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel. Therefore, diesel fuel needs good compression ignition characteristics. The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil, but alternatives that are not derived from petroleum, such as biodiesel, biomass to liquid (BTL) or gas to liquid (GTL) diesel are increasingly being developed and adopted. To distinguish these types, petroleum-derived diesel is sometimes called petrodiesel in some academic circles. Diesel is a high-volume product of oil refineries. In many countries, diesel fuel is standardized. For example, in the European Union, the standard for diesel fuel is EN 590. Ultra-low-sulfur diesel (ULSD) is a diesel fuel with ...

Kerosene
Kerosene, or paraffin, is a combustibility, combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in Aviation fuel, aviation as well as households. Its name derives from the Greek (''kērós'') meaning "wax"; it was registered as a trademark by Nova Scotian, Nova Scotia geologist and inventor Abraham Pineo Gesner, Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. Kerosene is widely used to power jet engines of aircraft (jet fuel), as well as some rocket engines in a highly refined form called RP-1. It is also commonly used as a cooking and lighting fuel, and for fire toys such as Poi (performance art)#Fire poi, poi. In parts of Asia, kerosene is sometimes used as fuel for small outboard motors or even motorcycles. World total kerosene consumption for all purposes is equivalent to about 5,500,000 barrels per day as of July 2023. The term "kerosene" is comm ...
