Hermes Project
Project Hermes was a missile research program run by the Ordnance Corps of the United States Army from November 15, 1944, to December 31, 1954, in response to Germany's rocket attacks in Europe during World War II. The program was to determine the missile needs of army field forces. A research and development partnership between the Ordnance Corps and General Electric started November 20, 1944 and resulted in the "development of long-range missiles that could be used against both ground targets and high-altitude aircraft." History Hermes was the second missile program by the United States Army. In May 1944 the Army contracted with the California Institute of Technology's Guggenheim Aeronautical Laboratories to start the ORDCIT project to research, test and develop guided missiles. The Hermes program was to originally have three phases: the first would be a literature search, the second a research group would be dispatched to Europe to investigate the German Missiles, and the t ...

White Sands Proving Ground
White Sands Missile Range (WSMR) is a United States Army military testing area and firing range located in the US state of New Mexico. The range was originally established as the White Sands Proving Ground on 9July 1945. White Sands National Park is located within the range. Significant events *The first atomic bomb (code named Trinity) was test detonated at Trinity Site near the northern boundary of the range on 16 July 1945, seven days after the White Sands Proving Ground was established. *After the conclusion of World War II, 100 long-range German V-2 rockets that were captured by U.S. military troops were brought to WSMR. Of these, 67 were test-fired between 1946 and 1951 from the White Sands V-2 Launching Site. (This was followed by the testing of American rockets, which continues to this day, along with testing other technologies.) *NASA's Space Shuttle Columbia landed on the Northrop Strip at WSMR on 30 March 1982 as the conclusion to mission STS-3. This was the only time ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V-2 Sounding Rocket
German V-2 rockets captured by the United States Army at the end of World War II were used as sounding rockets to carry scientific instruments into the Earth's upper atmosphere at White Sands Missile Range (WSMR) for a program of atmospheric and solar investigation through the late 1940s. Rocket trajectory was intended to carry the rocket about high and horizontally from WSMR Launch Complex 33. Impact velocity of returning rockets was reduced by inducing structural failure of the rocket airframe upon atmospheric re-entry. More durable recordings and instruments might be recovered from the rockets after ground impact, but telemetry was developed to transmit and record instrument readings during flight. History The first of 300 railroad cars of V-2 rocket components began to arrive at Las Cruces, New Mexico in July 1945 for transfer to WSMR. (So much equipment was taken from Germany that the Deutsches Museum later had to obtain a V-2 for an exhibit from the US.) In November Genera ...

Experimental Rockets Of The United States
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons (e. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Spaceflight Before 1951
Spaceflight as a practical endeavor began during World War II with the development of operational liquid-fueled rockets. Beginning life as a weapon, the V-2 was pressed into peaceful service after the war at the United States' White Sands Missile Range as well as the Soviet Union's Kapustin Yar. This led to a flourishing of missile designs setting the stage for the exploration of space. The small American WAC Corporal rocket was evolved into the Aerobee, a much more powerful sounding rocket. Exploration of space began in earnest in 1947 with the flight of the first Aerobee, 46 of which had flown by the end of 1950. These and other rockets, both Soviet and American, returned the first direct data on air density, temperature, charged particles and magnetic fields in the Earth's upper atmosphere. By 1948, the United States Navy had evolved the V-2 design into the Viking capable of more than in altitude. The first Viking to accomplish this feat, number four, did so 10 May 1950. The ...

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] |
Malta Test Station
Hermes A-1 Rocket test at White Sands, New Mexico. The Hermes A-1 used engines tested in Malta Malta Test Station, located in Malta, New York, is a former US Army fuel and explosives testing facility. It was established in 1945 and used to test rocket engines for the US Army's " Project Hermes", new fuels and explosives. It has also been used for atomic energy research. Malta test station has been used by various government agencies including the US Department of Defense, National Aeronautics and Space Agency (NASA), the US Department of Energy, and the New York State Energy Research and Development Authority (NYSERDA), it was operated by General Electric until 1972 when the Wright-Malta Corporation took over occupation and continued to test fuels and explosives for the US military and the US Department of Energy until 2005. The Wright Malta Corporation also worked on noise suppression systems, fuel cells, assisted technologically oriented start up businesses, waste-to-energy te ...

RTV-A-3 NATIV
The RTV-A-3 NATIV was an experimental missile developed by North American Aviation for the United States Air Force in the late 1940s to test and evaluate guided missile technologies. The North American Test Instrumentation Vehicle (NATIV) was developed as part of the MX-770 program which was created towards the end of WWII with the intent of developing a long range missile. Conception and design Exactly what the type of the missile, its range and payload were all changing during the period from the mid-1940s to early 1950s. One major consideration was that limited funds meant that an extensive build / test / modify process such as that used by the Germans in developing the V-2 was not possible. Due to budgetary restraints a great deal more information had to be readily derived from each of far fewer flights. On the RTV-A-2 (MX-774), a camera recorded the results displayed upon an instrument panel. Both the number of parameters recorded and the survivability of the film record we ...

Wasserfall
The ''Wasserfall Ferngelenkte FlaRakete'' (Waterfall Remote-Controlled A-A Rocket) was a German guided supersonic surface-to-air missile project of World War II. Development was not completed before the end of the war and it was not used operationally. The system was based on many of the technologies developed for the V-2 rocket program, including the rocket itself, which was essentially a much scaled-down version of the V-2 airframe. The rocket motor used new fuels as it was expected to be stored in ready-to-fire form for months, and the guidance system used external fins for control instead of relying entirely on the steerable rocket motor exhaust. Among the many development problems, control of the high-speed rocket was a significant concern, leading to the development of a radio control system where the operator sat in a reclining chair so they could see the target as it passed overhead. Another significant problem was the lack of a suitable proximity fuse, which was require ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 warhead which weighed with 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 Per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huntsville, Alabama
Huntsville is a city in Madison County, Limestone County, and Morgan County, Alabama, United States. It is the county seat of Madison County. Located in the Appalachian region of northern Alabama, Huntsville is the most populous city in the state. Huntsville was founded within the Mississippi Territory in 1805 and became an incorporated town in 1811. When Alabama was admitted as a state in 1819, Huntsville was designated for a year as the first capital, before that was moved to more central settlements. The city developed across nearby hills north of the Tennessee River, adding textile mills in the late nineteenth century. Its major growth has taken place since World War II. During the war, the Army established Redstone Arsenal near here with a chemical weapons plant, and nearby related facilities. After the war, additional research was conducted at Redstone Arsenal on rockets, followed by adaptations for space exploration. NASA's Marshall Space Flight Center, the Unit ...
