Skyship 600
The Airship Industries Skyship 600 is a modern airship, originally designed by British company Airship Industries, further developed by a subsidiary of Westinghouse Electric Corporation. The type certificate holder is now Skyship Services of Orlando, Florida. The first Skyship 600 made its maiden flight on 6 March 1984. By August 1987 a further six had been built and flown. The Skyship 600 is similar in appearance to, but larger than, the Skyship 500. Airship Industries collapsed in 1990. Westinghouse Electric's defense arm had taken over the US Navy's airship programme in which Airship Industries was a partner and bought the military marketing rights and intellectual rights to the Skyship designs from the official receiver. Slingsby Aviation, which was the principal subcontractor to Airship Industries bought other assets, marketing rights and intellectual property for civil versions along with the type certificates. Westinghouse purchased the Skyship 600S demonstrator, Air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floyd Bennett Field
Floyd Bennett Field is an airfield in the Marine Park, Brooklyn, Marine Park neighborhood of southeast Brooklyn in New York City, along the shore of Jamaica Bay. The airport originally hosted commercial and general aviation traffic before being used as a naval air station. Floyd Bennett Field is currently part of the Gateway National Recreation Area's Jamaica Bay Unit, and is managed by the National Park Service (NPS). While no longer used as an operational commercial, military, or general aviation airfield, a section is still used as a helicopter base by the New York City Police Department (NYPD), and one runway is reserved for hobbyists flying radio-controlled aircraft. Floyd Bennett Field was created by connecting Barren Island, Brooklyn, Barren Island and several smaller islands to the rest of Brooklyn by filling the Channel (geography), channels between them with sand pumped from the bottom of Jamaica Bay.

Zeppelin NT
The Zeppelin NT (''"Neue Technologie"'', German language, German for ''new technology'') is a class of helium-filled airships being manufactured since the 1990s by the German company Luftschiffbau Zeppelin, Zeppelin Luftschifftechnik GmbH (ZLT) in Friedrichshafen. The initial model is the N07. The company considers itself the successor of the companies founded by Ferdinand von Zeppelin which constructed and operated the very successful Zeppelin airships in the first third of the 20th century. There are, however, a number of notable differences between the Zeppelin NT and original Zeppelins as well as between the Zeppelin NT and usual non-rigid airships known as blimps. The Zeppelin NT is classified as a semi-rigid airship. There are various roles for the Zeppelin NT; traditional roles have been aerial tourism purposes and for conducting passenger services. The hull surfaces of the aircraft have also been used for advertising purposes. The Zeppelin NT have also been used for obse ...

Porsche 930
The Porsche 930 is a turbocharged variant of the 911 model sports car manufactured by German automobile manufacturer Porsche between 1975 and 1989. It was the maker's top-of-the-range 911 model for its entire production duration and, at the time of its introduction, was the fastest production car in Germany. Model history Porsche began experimenting with turbocharging technology on their race cars during the late 1960s, and in 1972 began development on a turbocharged version of the 911. Porsche originally needed to produce the car in order to comply with homologation regulations and had intended on marketing it as a street legal race vehicle like the 1973 Carrera 2.7 RS. The FIA's Appendix "J” rules upon which the 911 Turbo Carrera RSR 2.1 was entered into competition in 1974 changed in 1975 and 1976.

Ballonet
A ballonet is an inflatable bag inside the outer envelope of an airship which, when inflated, reduces the volume available for the lifting gas, making it more dense. Because air is also denser than the lifting gas, inflating the ballonet reduces the overall lift, while deflating it increases lift. In this way, the ballonet can be used to adjust the lift as required. Ballonets may typically be used in non-rigid or semi-rigid airships, commonly with multiple ballonets located both fore and aft to maintain balance and to control the pitch of the airship. The image illustrates the principle of a balloon within a balloon. The outer balloon represents the airship's outer envelope or gasbag, while the red inner balloon represents the ballonet. In an airship the ballonet would be much smaller relative to the size of the gasbag; for example, in the French airship Lebaudy Patrie the volume of the ballonet was approximately one-fifth that of the envelope. History The ballonet was fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marconi Company
The Marconi Company was a British telecommunications and engineering company founded by Italian inventor Guglielmo Marconi in 1897 which was a pioneer of wireless long distance communication and mass media broadcasting, eventually becoming one of the UK's most successful manufacturing companies. Its roots were in the Wireless Telegraph & Signal Company, which underwent several changes in name after mergers and acquisitions. In 1999, its defence equipment manufacturing division, Marconi Electronic Systems, merged with British Aerospace (BAe) to form BAE Systems. In 2006, financial difficulties led to the collapse of the remaining company, with the bulk of the business acquired by the Swedish telecommunications company, Ericsson.

Kevlar
Kevlar (para-aramid) is a strong, heat-resistant synthetic fiber, related to other aramids such as Nomex and Technora. Developed by Stephanie Kwolek at DuPont in 1965, the high-strength material was first used commercially in the early 1970s as a replacement for steel in racing tires. It is typically spun into ropes or fabric sheets that can be used as such, or as an ingredient in composite material components. Kevlar has many applications, ranging from bicycle tires and sailcloth#Kevlar, racing sails to bulletproof vests, due to its high Specific strength, tensile strength-to-weight ratio; by this measure it is five times stronger than steel. It is also used to make modern marching drumheads that withstand high impact, and for Mooring, mooring lines and other underwater applications. A similar fiber, Twaron, with the same chemical structure was developed by Akzo in the 1970s. Commercial production started in 1986, and Twaron is manufactured by Teijin Aramid. History Poly- ...
