Homer J. Stewart
Homer Joseph "Stewie" Stewart (1915–2007) was an American aeronautical engineer, rocket propulsion expert, and Caltech professor, who pioneered the first American satellites. Biography With a bachelor's degree from the University of Minnesota in 1936, Stewart matriculated at Caltech. In 1940 Stewart graduated from Caltech with a Ph.D. in aeronautics. In 1938, two years before earning his Ph.D., he became a Caltech faculty member. He taught aeronautics and meteorology, for many years dividing his time between teaching at Caltech and research at the Jet Propulsion Laboratory (JPL). In 1958 NASA (National Aeronautics and Space Administration) was formed as a response to the USSR's 1957 launch of ''Sputnik'' 1. From 1958 to 1960, Stewart took a two-year leave of absence from Caltech to serve as NASA's director of planning and evaluation. He was in charge of calculating and analyzing the exhaust velocities required to lift rockets to their planned orbits. In addition to cont ...

Jupiter-C
The Jupiter-C was an American research and development vehicle developed from the Jupiter-A. Jupiter-C was used for three unmanned sub-orbital spaceflights in 1956 and 1957 to test re-entry nosecones that were later to be deployed on the more advanced PGM-19 Jupiter mobile missile. The recovered nosecone was displayed in the Oval Office as part of President Dwight D. Eisenhower's televised speech on November 7, 1957. A member of the Redstone rocket family, Jupiter-C was designed by the U.S. Army Ballistic Missile Agency (ABMA), under the direction of Wernher von Braun. Three Jupiter-C flights were made followed by three satellite launches (Juno I). All were launched from Cape Canaveral, Florida. Description Each vehicle consisted of a modified Redstone ballistic missile with two solid-propellant upper stages. The tanks of the Redstone were lengthened by 8 ft (2.4 m) to provide additional propellant. The instrument compartment was also smaller and lighter than the Reds ...

People From Lapeer County, Michigan
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Smith–Putnam Wind Turbine
The Smith–Putnam wind turbine was the world's first megawatt-size wind turbine. In 1941 it was connected to the local electrical distribution system on Grandpa's Knob in Castleton, Vermont, US. It was designed by Palmer Cosslett Putnam and manufactured by the S. Morgan Smith Company. The 1.25 MW turbine operated for 1100 hours before a blade failed at a known weak point, which had not been reinforced due to wartime material shortages. It would be the largest wind turbine ever built until 1979. Description The turbine had two blades, in diameter, on the down-wind side of a -foot steel lattice tower. Each blade was approximately wide and long, and weighed eight tons. The blades were built on steel spars and covered with a stainless steel skin. The blade spars were hinged at their root attachment to the hub, allowing them to assume a slight cone shape. The generator was a 1250 kva 600 RPM synchronous generator made by General Electric, producing 2,400 V at 60 cycles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wernher Von Braun
Wernher Magnus Maximilian Freiherr von Braun ( , ; 23 March 191216 June 1977) was a German and American aerospace engineer and space architect. He was a member of the Nazi Party and Allgemeine SS, as well as the leading figure in the development of rocket technology in Nazi Germany and later a pioneer of rocket and space technology in the United States. As a young man, von Braun worked in Nazi Germany's rocket development program. He helped design and co-developed the V-2 rocket at Peenemünde during World War II. Following the war, he was secretly moved to the United States, along with about 1,600 other German scientists, engineers, and technicians, as part of Operation Paperclip. He worked for the United States Army on an intermediate-range ballistic missile program, and he developed the rockets that launched the United States' first space satellite Explorer 1 in 1958. He worked with Walt Disney on a series of films, which popularized the idea of human space travel in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
