XCOR EZ-Rocket
The XCOR EZ-Rocket was a test platform for the XCOR XR-4A3 rocket propulsion system. The airplane was a modified Rutan Long-EZ, with the propeller replaced by first one, then later a pair of pressure-fed regeneratively cooled liquid-fueled rocket engines and an underslung fuel tank. The engines were restartable in flight, and were contained within Kevlar armor shielding. The EZ-Rocket was registered as an experimental aircraft. Development and history The first flight took place on July 21, 2001, flown by test pilot Dick Rutan. On a typical flight, the EZ-Rocket took off on rockets, gained altitude for a minute or so, then switched off the rockets and glided to a dead stick landing. The vehicle actually flew better during dead stick landings than a standard Long-EZ due to lack of drag from a stationary pusher propeller — the vehicle's aerodynamics were cleaner in spite of its belly tank. It was also lighter due to the lack of a piston engine (the rocket propulsion sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EAA AirVenture Oshkosh
EAA AirVenture Oshkosh (formerly the EAA Annual Convention and Fly-In), or just Oshkosh, is an annual air show and gathering of aviation enthusiasts held each summer at Wittman Regional Airport and adjacent Pioneer Airport in Oshkosh, Wisconsin, United States. The southern part of the show grounds, as well as Camp Scholler, are located in the town of Nekimi and a base for seaplanes on Lake Winnebago is in Black Wolf. The airshow is arranged by the Experimental Aircraft Association (EAA), an international general aviation organization based in Oshkosh, and is the largest of its kind in the world. The show lasts a week, usually beginning on the Monday of the last full week in July. During the gathering, the airport's control tower, frequency 118.5, is the busiest in the world. History EAA was founded in Hales Corners, Wisconsin in 1953 by aircraft designer and military aviator veteran Paul Poberezny, who originally started the organization in the basement of his home for bu ...

Isopropyl Alcohol
Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable organic compound with a pungent alcoholic odor. As an isopropyl group linked to a hydroxyl group ( chemical formula ) it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms. It is a structural isomer of propan-1-ol and ethyl methyl ether. It is used in the manufacture of a wide variety of industrial and household chemicals and is a common ingredient in products such as antiseptics, disinfectants, hand sanitizer and detergents. Well over one million tonnes is produced worldwide annually. Properties Isopropyl alcohol is miscible in water, ethanol, and chloroform as, like these compounds, isopropyl is a polar molecule. It dissolves ethyl cellulose, polyvinyl butyral, many oils, alkaloids, and natural resins. Unlike ethanol or methanol, isopropyl alcohol is not miscible with salt solutions an ...

RP-1
RP-1 (alternatively, Rocket Propellant-1 or Refined Petroleum-1) is a highly refined form of kerosene outwardly similar to jet fuel, used as rocket fuel. RP-1 provides a lower specific impulse than liquid hydrogen (LH2), but is cheaper, is stable at room temperature, and presents a lower explosion hazard. RP-1 is far denser than LH2, giving it a higher energy density (though its specific energy is lower). RP-1 also has a fraction of the toxicity and carcinogenic hazards of hydrazine, another room-temperature liquid fuel. Usage and history RP-1 is a fuel in the first-stage boosters of the Electron, Soyuz, Zenit, Delta I-III, Atlas, Falcon, Antares, and Tronador II rockets. It also powered the first stages of the Energia, Titan I, Saturn I and IB, and Saturn V. The Indian Space Research Organization (ISRO) is also developing an RP-1 fueled engine for its future rockets. Development During and immediately after World War II, alcohols (primarily ethanol, occasionally me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

X-Racer
The Rocket Racing League was a racing league that planned to use rocket-powered aircraft to race a closed-circuit air racetrack. Founded in 2005, the league made its first public flights in 2010 and was working to begin regular racing seasons. The "Rocket Racers" were slated to compete in the air and on a virtual racetrack easily viewed by a live audience as well as projected on large screen and handheld electronic displays. Three prototype canard-style ''Rocket Racer'' aircraft were built between 2006 and 2010. The league had planned to hold its inaugural race season in 2008 with four races, but encountered financial difficulties that delayed fielding of ''Rocket Racers'' by the six teams that had been previously announced. With the addition of venture capital funding in mid-2009, technology development continued and one exhibition occurred in 2010, with another round of plans for an inaugural season of races in 2011. The 2011 races were, in the end, never scheduled, and by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Richard A
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include "Richie", "Dick", "Dickon", " Dickie", " Rich", "Rick", " Rico", " Ricky", and more. Richard is a common English, German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Catalan "Ricard" and the Italian "Riccardo", among others (see comprehensive variant list below).
