Project Skyhook
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 develope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mylar
BoPET (biaxially-oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, chemical and dimensional stability, transparency, reflectivity, gas and aroma barrier properties, and electrical insulation. A variety of companies manufacture boPET and other polyester films under different brand names. In the UK and US, the best-known trade names are Mylar, Melinex, and Hostaphan. History BoPET film was developed in the mid-1950s,Izard, Emmette Farr"Production of polyethylene terephthalate" U.S. patent no. 2,534,028 (filed: 1948 May 13; issued: 1950 December 12). originally by DuPont, Imperial Chemical Industries (ICI), and Hoechst.

Deacon (rocket)
Deacon is the designation of an American sounding rocket. The Deacon was launched 90 times from 1947 to 1957 from Wallops Island, and it also was the rocket portion of the first rockoons, launched 1952 to 1956. The Deacon has a maximum flight height of 20 kilometers and a pay load ability of 17 kilograms. The takeoff thrust of the Deacon amounts to 27 kN, the takeoff weight In science and engineering, the weight of an object is the force acting on the object due to gravity. Some standard textbooks define weight as a vector quantity, the gravitational force acting on the object. Others define weight as a scalar qua ... 93 kg, the diameter 0.16 m and the length 3.28 m.

Rockoon
A rockoon (from ''rocket'' and ''balloon'') is a solid fuel sounding rocket that, rather than being immediately lit while on the ground, is first carried into the upper atmosphere by a gas-filled balloon, then separated from the balloon and ignited. This allows the rocket to achieve a higher altitude, as the rocket does not have to move under power through the lower and thicker layers of the atmosphere. The original concept was developed by Cmdr. Lee Lewis, Cmdr. G. Halvorson, S. F. Singer, and James A. Van Allen during the Aerobee rocket firing cruise of the U.S.S. ''Norton Sound'' on March 1, 1949. A serious disadvantage is that unpiloted balloons cannot be steered, and consequently the location from which the rocket is launched can be uncertain. Therefore, a large area for the fall of the rocket is required for safety reasons. Early atmospheric research ''Time'' magazine reported in 1959: "Van Allen's 'Rockoons' could not be fired in Iowa for fear that the spent rocket ...

USS Norton Sound (AV-11) Launches A Skyhook Balloon On 31 March 1949
USS ''Norton Sound'' (AV-11/AVM-1) was originally built as a by Los Angeles Shipbuilding and Dry Dock Company, San Pedro, California. She was named for Norton Sound, a large inlet in West Alaska, between the Seward Peninsula and the mouths of the Yukon, north-east of the Bering Sea. Career ''Norton Sound'' was laid down 7 September 1942 and launched 28 November 1943. The ship was sponsored by Mrs. Ernest L. Gunther, wife of Rear Admiral Ernest L. Gunther, and commissioned 8 January 1945. World War II After Pacific shakedown, the new seaplane tender stood out from San Diego 26 February 1945 and steamed for Pearl Harbor, Hawaii. She reported to Commander, Marshall- Gilbert area for training in mid-March, and she arrived Saipan 1 April 1945 to provide seaplane tending services. ''Norton Sound'' anchored 1 May 1945 at Aka Kaikyo, Kerama Retto, and by 21 June 1945 had assisted in downing three hostile air raiders. Air alerts continued until midnight, 14 August 1945.

United States Atomic Energy Commission
The United States Atomic Energy Commission (AEC) was an agency of the United States government established after World War II by U.S. Congress to foster and control the peacetime development of atomic science and technology. President Harry S. Truman signed the McMahon/Atomic Energy Act on August 1, 1946, transferring the control of atomic energy from military to civilian hands, effective on January 1, 1947. This shift gave the members of the AEC complete control of the plants, laboratories, equipment, and personnel assembled during the war to produce the atomic bomb. An increasing number of critics during the 1960s charged that the AEC's regulations were insufficiently rigorous in several important areas, including radiation protection standards, nuclear reactor safety, plant siting, and environmental protection. By 1974, the AEC's regulatory programs had come under such strong attack that the U.S. Congress decided to abolish the AEC. The AEC was abolished by the En ...

Winzen Research
Winzen Research Inc, Minneapolis, Minnesota, created balloons in the 1950s and 1960s that were used by the United States Navy in its Projects Helios, Skyhook, and Strato-Lab. Balloons were also sold to the United States Air Force for use in Project Manhigh and for a secret reconnaissance mission, called Moby Dick, to overfly the Soviet Union. Otto C. Winzen developed the use of polyethylene resin for plastic balloons. Polyethylene balloons vastly reduced the weight in comparison with previously used rubber materials. Polyethylene was light, relatively cheap, and unaffected by ultraviolet radiation. Winzen refined the manufacturing techniques to reduce the plastics used in the balloons to less than the thickness of a human hair The company was created by Otto Winzen and his wife Vera Simons. Vera, eventually an accomplished balloonist herself, borrowed money from her parents to help start Winzen Research. She held over two-thirds ownership of the company and became its vice pres ...
