X-1E
The Bell X-1 (Bell Model 44) is a rocket engine–powered aircraft, designated originally as the XS-1, and was a joint National Advisory Committee for Aeronautics–U.S. Army Air Forces–U.S. Air Force supersonic research project built by Bell Aircraft. Conceived during 1944 and designed and built in 1945, it achieved a speed of nearly in 1948. A derivative of this same design, the Bell X-1A, having greater fuel capacity and hence longer rocket burning time, exceeded in 1954. The X-1 aircraft #46-062, nicknamed ''Glamorous Glennis'' and flown by Chuck Yeager, was the first piloted airplane to exceed the speed of sound in level flight and was the first of the X-planes, a series of American experimental rocket planes (and non-rocket planes) designed for testing new technologies. Design and development Parallel development In 1942, the United Kingdom's Ministry of Aviation began a top secret project with Miles Aircraft to develop the world's first aircraft capable of breaking ...

X-plane (aircraft)
The X-planes are a series of experimental United States aircraft and rockets, used to test and evaluate new technologies and aerodynamic concepts. They have an X designator within the United States Department of Defense aerospace vehicle designation, US system of aircraft designations, which denotes the experimental research mission. Not all US experimental aircraft have been designated as X-planes; some received List of United States Navy aircraft designations (pre-1962), US Navy designations before 1962, while others have been known only by manufacturers' designations, non-'X'-series designations, or classified codenames. This list only includes the designated X-planes. History The X-planes concept officially came into being in 1944, as a joint programme involving the National Advisory Committee for Aeronautics (NACA), the US Navy (USN) and the US Army Air Forces (USAAF), in order to pursue research into high-speed aircraft.Miller 1983, p.9.

Reaction Motors Inc
Reaction Motors, Inc. (RMI) was an early American maker of liquid-fueled rocket engines, located in New Jersey. RMI engines with thrust powered the Bell X-1 rocket aircraft that first broke the sound barrier in 1947, and later aircraft such the X-1A, X-1E, and the Douglas D-558-2 Skyrocket. A thrust RMI engine also powered the Viking research rocket, the first large liquid-fueled US high-altitude rocket. RMI was merged with Thiokol in 1958, where it produced the XLR-99 engine that powered the X-15 rocket aircraft. History Formation and the sound barrier Reaction Motors, Inc. began operation as early as 1930 through the work of then American Interplanetary Society members Lovell Lawrence, George Edward Pendray, Hugh Pierce, and engineer John Shesta. This group quickly moved from science fiction discussions to practical rocketry. Pendray contributed heavily to their early designs using knowledge acquired from a trip to Berlin in 1931. In 1938, Princeton University ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell Aircraft
The Bell Aircraft Corporation was an American aircraft manufacturer, a builder of several types of fighter aircraft for World War II but most famous for the Bell X-1, the first supersonic aircraft, and for the development and production of many important civilian and military helicopters. Bell also developed the Reaction Control System for the Project Mercury, Mercury Spacecraft, North American X-15, and Bell Rocket Belt. The company was purchased in 1960 by Textron, and lives on as Bell Textron. History As a pilot, Lawrence Dale Bell, Larry Bell saw his first plane at an air show, starting a lifelong fascination with aviation. Bell dropped out of high school in 1912 to join his brother in the burgeoning aircraft industry at the Glenn L. Martin Company, where by 1914 he had become shop superintendent. By 1920, Bell was vice president and general manager of Martin, then based in Cleveland. Feeling that he deserved part ownership, in late 1924, he presented Martin with an ultimatum. ...

XLR-11
XLR-11 (5"-fluoro-UR-144 or 5F-UR-144) is a drug that acts as a potent agonist for the cannabinoid receptors CB1 and CB2 with EC50 values of 98 nM and 83 nM, respectively. It is a 3-(tetramethylcyclopropylmethanoyl)indole derivative related to compounds such as UR-144, A-796,260 and A-834,735, but it is not specifically listed in the patent or scientific literature alongside these other similar compounds, and appears to have not previously been made by Abbott Laboratories, despite falling within the claims of patent WO 2006/069196. XLR-11 was found to produce rapid, short-lived hypothermic effects in rats at doses of 3 mg/kg and 10 mg/kg, suggesting that it is of comparable potency to APICA and STS-135. Detection A forensic standard for this compound is available, and a representative mass spectrum has been posted on Forendex. Recreational use XLR-11 was instead first identified by laboratories in 2012 as an ingredient in synthetic cannabis smoking blends, and ...

Tex Johnston
Alvin Melvin "Tex" Johnston (August 18, 1914 – October 29, 1998) was an American test pilot for Bell Aircraft and the Boeing Company. Early life Johnston was born August 18, 1914, in Admire, Kansas, to farmers Alva and Ella Johnston. He had his first airplane ride in 1925, at 11 years old, when a barnstormer landed near his family farm. At the age of 15, Johnston used his newspaper route money to purchase a wrecked Cessna glider. After repairing the glider, Johnston's father would pull it behind their car and Johnston would release the tow cable and glide to a landing in a nearby field. After graduating from Emporia High School in 1932, Johnston enrolled in the airplane mechanic program at the Spartan School of Aeronautics in Tulsa, Oklahoma. Once Johnston became an apprentice mechanic, he was able to offset his flight training costs by working on the school's aircraft. After graduating from Spartan, Johnston joined Inman's Flying Circus, working as both a pilot and mec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Airspeed Record
An air speed record is the highest airspeed attained by an aircraft of a particular class. The rules for all official aviation records are defined by Fédération Aéronautique Internationale (FAI), which also ratifies any claims. Speed records are divided into a number of classes with sub-divisions. There are three classes of aircraft: landplanes, seaplanes, and amphibious aircraft, amphibians, and within these classes there are records for aircraft in a number of weight categories. There are still further subdivisions for Reciprocating engine, piston-engined, turbojet, turboprop, and Rocket engine, rocket-engined aircraft. Within each of these groups, records are defined for speed over a straight course and for closed circuits of various sizes carrying various payloads. Timeline Gray text indicates unofficial records, including unconfirmed or unpublicized war secrets.
