Otto C. Winzen
Otto C. Winzen (1917–1979) was a German-American aeronautics engineer who made significant advances in the materials and construction of high-altitude balloons after World War II. Winzen emigrated to the United States in 1937 and spent time during the war in internment camps. He studied aeronautical engineering at the University of Detroit. After World War II, Winzen became involved in high-altitude balloon research, working with Jean Piccard. In 1949 he started his own company with his wife Vera Simons, called Winzen Research, Inc.} He created a number of plastic balloons, in particular of polyethylene, which he sold to the United States Army and Navy including the Skyhook balloon, and the Air Force's Project Manhigh. In 1972 he developed the Winzen Research Balloon, which achieved the record for the highest unmanned balloon flight, setting a record altitude of 51,816 m over Chico, California Chico ( ; Spanish for "little") is the most populous city in Butte County, ...

Aeronautics Engineer
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: Aeronautics, aeronautical engineering and Astronautics, astronautical engineering. Avionics engineering is similar, but deals with the electronic engineering, electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, A ...

Project Manhigh
Project Manhigh was a pre-Space Age military project that took men in balloons to the middle layers of the stratosphere, funded as an aero-medical research program, though seen by its designers as a stepping stone to space. It was conducted by the United States Air Force between 1955 and 1958. History The project started in December 1955 to study the effects of cosmic rays on humans. Three balloon flights to the stratosphere were made during the program: * Manhigh I to , by Captain Joseph W. Kittinger on June 2, 1957. The balloon was launched from South St. Paul Airport and the flight was cut short due to one of the capsule's valves being installed backwards which vented the oxygen supply outside, but not before reaching a record altitude of 96,784 feet. * Manhigh II to , by Major David G. Simons on August 19–20, 1957, launched from Portsmouth Mine in Crosby, Minnesota, for a 32-hour flight that included a set of 25 experiments and observations, and earned Simons a ...

The journal became an outlet for writings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centennial Of Flight Commission
The U. S. Centennial of Flight Commission (CoFC or CofF Commission) was created in 1999, by the U.S. Congress, to serve as a national and international source of information about activities commemorating the centennial of the Wright brothers' first powered flight on December 17, 1903 (purportedly the first fully controlled, sustained, powered flight of a heavier-than-air man-carrying airplane).Review"U.

Chico, California
Chico ( ; Spanish for "little") is the most populous city in Butte County, California. Located in the Sacramento Valley region of Northern California, the city had a population of 101,475 in the 2020 census, reflecting an increase from 86,187 in the 2010 Census. Chico is the cultural and economic center of the northern Sacramento Valley, as well as the largest city in California north of the capital city of Sacramento. The city is known as a college town, as the home of California State University, Chico, and for Bidwell Park, one of the largest urban parks in the world. History The first known inhabitants of the area now known as Chico—a Spanish word meaning "little"—were the Mechoopda Maidu Native Americans. The City of Chico was founded in 1860 by John Bidwell, a member of one of the first wagon trains to reach California in 1843. During the American Civil War, Camp Bidwell (named for John Bidwell, by then a brigadier general of the California Militia), was es ...

Skyhook Balloon
Skyhook balloons were high-altitude balloons developed by Otto C. Winzen and General Mills, Inc. They were used by the United States Navy Office of Naval Research (ONR) in the late 1940s and 1950s for atmospheric research, especially for constant-level meteorological observations at very high altitudes. Instruments like the Cherenkov detector were first used on Skyhook balloons. Project Skyhook In the late 1940s, Project Skyhook was conceived of as a means by which plastic balloons could be used to transmit or send instruments into the stratosphere to conduct research. This project carried forward work from an earlier project, Helios, that General Mills and Jean Piccard initiated to use arrays of giant plastic balloons to carry humans aloft. Balloons, long used for collecting meteorological data, now offered the opportunity of collecting highly specialized information and photographs. The first Skyhook balloon was launched on September 25, 1947. The balloon was developed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-altitude Balloons
High-altitude balloons are crewed or uncrewed balloons, usually filled with helium or hydrogen, that are released into the stratosphere, generally attaining between above sea level. In 2002, a balloon named BU60-1 reached a record altitude of . The most common type of high-altitude balloons is weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. These balloons are launched into what is termed "near space", defined as the area of Earth's atmosphere between the Armstrong limit ( above sea level), where pressure falls to the point that a human being cannot survive without a pressurised suit, and the Kármán line ( above sea level), where astrodynamics must take over from aerodynamics in order to maintain flight. Due to the low cost of GPS and communications equipment, high-altitude balloon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyethylene
Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic. It is a polymer, primarily used for packaging ( plastic bags, plastic films, geomembranes and containers including bottles, etc.). , over 100 million tonnes of polyethylene resins are being produced annually, accounting for 34% of the total plastics market. Many kinds of polyethylene are known, with most having the chemical formula (C2H4)''n''. PE is usually a mixture of similar polymers of ethylene, with various values of ''n''. It can be ''low-density'' or ''high-density'': low-density polyethylene is extruded using high pressure () and high temperature (), while high-density polyethylene is extruded using low pressure () and low temperature (). Polyethylene is usually thermoplastic, but it can be modified to become thermosetting instead, for example, in cross-linked polyethylene. History Polyethylene was first synthesized by the German chemist Hans ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
