411th Flight Test Squadron
The 411th Flight Test Squadron is a United States Air Force squadron assigned to the 412th Operations Group of Air Force Materiel Command, stationed at Edwards Air Force Base, California. It conducted the Advanced Tactical Fighter program flyoff competition between the Lockheed YF-22 and Northrop YF-23 prototypes. Following the completion of the competition, the squadron has conducted testing of the Lockheed Martin F-22. History The squadron was first activated as the 6511th Test Squadron in March 1989 to conduct the Advanced Tactical Fighter program. It began flying the Northrop YF-23 on 27 August and the Lockheed YF-22 on 29 September 1990, flying both through December 1990, though the airplanes were assigned to the manufacturers rather than to USAF. The YF-22 (and the Pratt & Whitney F119 engine) was declared the winner of the competition on 23 April 1991, and on 2 August 1991 both YF-22 prototypes were transferred to the Air Force.Rogers, Though the Number 1 YF-22 retur ...

Air Force Materiel Command
Air Force Materiel Command (AFMC) is a major command (MAJCOM) of the United States Air Force (USAF). AFMC was created on July 1, 1992, through the amalgamation of the former Air Force Logistics Command (AFLC) and the former Air Force Systems Command (AFSC). AFMC is headquartered at Wright-Patterson Air Force Base in Dayton, Ohio. AFMC is one of nine Air Force Major Commands and has a workforce of approximately 80,000 military and civilian personnel. It is the Air Force's largest command in terms of funding and second in terms of personnel. AFMC's operating budget represents 31 percent of the total Air Force budget and AFMC employs more than 40 percent of the Air Force's total civilian workforce. The command conducts research, development, testing and evaluation, and provides the acquisition and life cycle management services and logistics support. The command develops, acquires and sustains the air power needed to defend the United States and its interests. This is accomplished ...

Lockheed Martin F-22A Raptor
The Lockheed Martin F-22 Raptor is an American single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). As the result of the USAF's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also has ground attack, electronic warfare, and signals intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems. The aircraft first flew in 1997 and was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Although the USAF had originally planned to buy a total of 750 ATFs, the program was cut to 187 operational aircraft in 2009 due to high costs, a lack of air-to-air missions due to the focus on counterinsurgency operations at the time of producti ...

6510th Test Wing
Year 651 ( DCLI) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. The denomination 651 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Europe * King Clovis II of Neustria and Burgundy marries Balthild, said to be an Anglo-Saxon aristocrat sold into slavery in Gaul. She has been owned by Clovis' mayor of the palace, Erchinoald, who gives her to him to garner royal favour (approximate date).

Mach Number
Mach number (M or Ma) (; ) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after the Moravian physicist and philosopher Ernst Mach. : \mathrm = \frac, where: : is the local Mach number, : is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and : is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach1, the local flow velocity is equal to the speed of sound. At Mach0.65, is 65% of the speed of sound (subsonic), and, at Mach1.35, is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed, but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number. The local spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camelina
''Camelina'' is a genus within the flowering plant family Brassicaceae. The ''Camelina'' species, commonly known as false flax, are native to Mediterranean regions of Europe and Asia. Most species of this genus have been little studied, with the exception of ''Camelina sativa'', historically cultivated as an oil plant. Heinrich Johann Nepomuk von Crantz was the first botanist to use the genus ''Camelina'' in his classification works in 1762. As a way to reduce fossil fuel emissions, the US Navy tested a 50-50 mix of jet aviation fuel and biofuel derived from camelina seeds in 2010. A study published in December 2016 explained that the current low price of conventional kerosene-based jet fuel makes it cost-prohibitive for commercial airlines to use camelina-based jet fuel. The study said substantial government intervention would be one way to create a market for camelina, by combining 9 percent government subsidy on camelina crop production, with 9 percent tax on the conventional fu ...

F-22 CRIIS Edwards
Fluoride (). According to this source, is a possible pronunciation in British English. is an inorganic, monatomic anion of fluorine, with the chemical formula (also written ), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless. Its salts and minerals are important chemical reagents and industrial chemicals, mainly used in the production of hydrogen fluoride for fluorocarbons. Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride is corrosive and can attack the skin. Fluoride is the simplest fluorine anion. In terms of charge and size, the fluoride ion resembles the hydroxide ion. Fluoride ions occur on Earth in several minerals, particularly fluorite, but are present only in trace quantities in bodies of water in nature. Nomenclature Fluorides include compounds that contain ionic fluoride and those in which fluoride does not dissociate. The nomenc ...

David P
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David ...

Langley Air Force Base
Langley Air Force Base is a United States Air Force base located in Hampton, Virginia, adjacent to Newport News, Virginia, Newport News. It was one of List of airfields of the Training Section of the United States Army Air Service, thirty-two Air Service training camps established after the entry of the United States into World War I in April 1917. On 1 October 2010, Langley Air Force Base was joined with Fort Eustis to become Joint Base Langley–Eustis. The base was established in accordance with congressional legislation implementing the recommendations of the 2005 Base Realignment and Closure Commission. The legislation ordered the consolidation of the two facilities which were nearby, but separate military installations, into a single joint base, one of 12 formed in the United States as a result of the law. Overview The Air Force mission at Langley is to sustain the ability for fast global deployment and air superiority for the United States or allied armed forces. The b ...
