Lockheed WC-130
The Lockheed WC-130 is a high-wing, medium-range aircraft used for weather reconnaissance missions by the United States Air Force. The aircraft is a modified version of the C-130 Hercules transport configured with specialized weather instrumentation including a dropsonde deployment/receiver system and crewed by a meteorologist for penetration of tropical cyclones and winter storms to obtain data on movement, size and intensity. The USAF's Air Weather Service (AWS) received its first C-130 Hercules in 1962 to conduct air sampling missions in the wake of a resumption of atmospheric weapons testing by the Soviet Union in September 1961. The Air Force was then in the process of replacing its fleet of Boeing B-50 Superfortress, WB-50 weather reconnaissance aircraft with Boeing B-47 Stratojet, WB-47E jets but by 1965 the AWS had decided it would better served by the WC-130 in the manned weather reconnaissance role. Since that year the Air Force and Air Force Reserve Command, Air Force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Force Reserve Command
The Air Force Reserve Command (AFRC) is a major command (MAJCOM) of the United States Air Force, with its headquarters at Robins Air Force Base, Georgia. It is the federal Air Reserve Component (ARC) of the U.S. Air Force, consisting of commissioned officers and enlisted airmen. AFRC also plays an integral role in the day-to-day Air Force mission and is not strictly a force held in reserve for possible war or contingency operations. AFRC also supports the United States Space Force through the 310th Space Wing, pending the creation of a space reserve component. Overview The federal reserve component of the United States Air Force, AFRC has approximately 450 aircraft assigned for which it has sole control, as well as access to several hundred additional active duty USAF aircraft via AFRC "Associate" wings that are collocated with active duty Air Force wings, sharing access to those same active duty Air Force aircraft. The inventory, both AFRC-controlled and active duty Regular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Defense Command
Aerospace Defense Command was a major command of the United States Air Force, responsible for continental air defense. It was activated in 1968 and disbanded in 1980. Its predecessor, Air Defense Command, was established in 1946, briefly inactivated in 1950, reactivated in 1951, and then redesignated ''Aerospace'' rather than ''Air'' in 1968. Its mission was to provide air defense of the Continental United States (CONUS). It directly controlled all active measures, and was tasked to coordinate all passive means of air defense. Air defense during World War II Continental United States air defense forces during World War II were initially under the command of the four air districts – Northeast Air District, Northwest Air District, Southeast Air District, and Southwest Air District. The air districts were established on 16 January 1941, before the Pearl Harbor attack. The four air districts also handled USAAF combat training with the Army Ground Forces and "organization a ...

Curtis E
Curtis or Curtiss is a common English given name and surname of Anglo-Norman origin from the Old French ''curteis'' (Modern French ''courtois'') which derived from the Spanish Cortés (of which Cortez is a variation) and the Portuguese and Galician Cardoso. The name means "polite, courteous, or well-bred". It is a compound of ''curt-'' "court" and ''-eis'' "-ish". The spelling ''u'' to render in Old French was mainly Anglo-Norman and Norman, when the spelling ''o'' was the usual Parisian French one, Modern French ''ou'' ''-eis'' is the Old French suffix for ''-ois'', Western French (including Anglo-Norman) keeps ''-eis'', simplified to ''-is'' in English. The word ''court'' shares the same etymology but retains a Modern French spelling, after the orthography had changed.T. F. Hoad, ''English Etymology'', Oxford University Press paperbook 1993. p. 101a It was brought to England (and subsequently, the rest of the Isles) via the Norman Conquest.

ICBM
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than , primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, the United States, China, France, India, the United Kingdom, and North Korea are the only countries known to have operational ICBMs. Early ICBMs had limited precision, which made them suitable for use only against the largest targets, such as cities. They were seen as a "safe" basing option, one that would keep the deterrent force close to home where it would be difficult to attack. Attacks against military targets (especially hardened ones) still demanded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metal Fatigue
In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface. The crack will continue to grow until it reaches a critical size, which occurs when the stress intensity factor of the crack exceeds the fracture toughness of the material, producing rapid propagation and typically complete fracture of the structure. Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal ''crystallising'' because of the brittle appearance of the fracture surface, but this has since been disproved. Most materials, such as composites, plastics and ceramics, seem to experience some sort of fatigue-related failure. To aid in predicting ...

Boeing B-29 Superfortress Variants
The Boeing B-29 Superfortress is a WWII era long range, strategic heavy bomber that was produced in many experimental and production models. XB-29 : ''Section source: Baugher'' The XB-29, Boeing Model 345, was the first accepted prototype or experimental model delivered to the Army Air Corps, incorporating a number of improvements on the design originally submitted, including more and larger guns and self-sealing fuel tanks. Two aircraft were ordered in August 1940, and a third was ordered in December. A mockup was completed in the spring of 1941, and it first flew on September 21, 1942. Testing was conducted on the XB-29 until February 18, 1943, when the second prototype crashed. The flight was conducted by Boeing's chief test pilot, Edmund T. "Eddie" Allen on a two-hour powerplant performance test. The accident happened when leaking fuel from a filler cap in the wing leading edge ran down inside the leading-edge and ignited. The fire spread to the engines, and due to the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
