Vertical Wind Tunnel
A vertical wind tunnel (VWT) is a wind tunnel that moves air up in a vertical column. Unlike standard wind tunnels, which have test sections that are oriented horizontally, as experienced in level flight, a vertical orientation enables gravity to be countered by drag instead of lift, as experienced in an aircraft spin or by a skydiver at terminal velocity. Although vertical wind tunnels have been built for aerodynamic research, the most high-profile are those used as recreational wind tunnels, frequently advertised as indoor skydiving or bodyflight, which have also become a popular training tool for skydivers. Recreational vertical wind tunnels A recreational wind tunnel enables human beings to experience the sensation of flight without planes or parachutes, through the force of wind being generated vertically. Air moves upwards at approximately 195 km/h (120 mph or 55 m/s), the terminal velocity of a falling human body belly-downwards. A vertical wind tunnel is ...

Acrophobia
Acrophobia is an extreme or irrational fear or phobia of heights, especially when one is not particularly high up. It belongs to a category of specific phobias, called space and motion discomfort, that share both similar causes and options for treatment. Most people experience a degree of natural fear when exposed to heights, known as the fear of falling. On the other hand, those who have little fear of such exposure are said to have a head for heights. A head for heights is advantageous for those hiking or climbing in mountainous terrain and also in certain jobs such as steeplejacks or wind turbine mechanics. People with acrophobia can experience a panic attack in high places and become too agitated to get themselves down safely. Approximately 2–5% of the general population has acrophobia, with twice as many women affected as men. The term is from the el, ἄκρον, , meaning "peak, summit, edge" and , , "fear". Confusion with vertigo "Vertigo" is often used to descri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mass Market
The term "mass market" refers to a market for goods produced on a large scale for a significant number of end consumers. The mass market differs from the niche market in that the former focuses on consumers with a wide variety of backgrounds with no identifiable preferences and expectations in a large market segment.“Niche Market.” ''Business: The ultimate resource''. (2002). Cambridge, Massachusetts: Perseus Publications:1294. Traditionally, businesses reach out to the mass market with advertising messages through a variety of media including radio, TV, newspapers and the Web. Definition Scholars have noted that defining the precise nature of the mass market is problematic. This difficulty arises, at least in part, from scholarly attention being given to the process of mass marketing rather than the mass market, per se. In addition, the concept of a mass market means different things in different contexts and has evolved over time, adding yet another layer of complexity. The ...

Aerodium
Aerodium is a designer and producer of vertical wind tunnels based in Riga, Latvia. Its core business is related to sales and rent of wind tunnels for entertainment and military industries, but it also operates different locations under franchise. A second part is connected to organizing shows and performances for brand promotion, festivals and other celebrations around the world. History In 1979 the Canadian inventor Jean Saint-Germain came up with the idea of the first vertical wind tunnel for bodyflight. After accumulating investments of $450,000, he opened the first commercial wind tunnel in Saint-Simon-de-Bagot, 50 miles east of Montreal. Saint-Germain, who was a former parachutist in the army, owned two parachute schools as he came to the idea that an Aerodium would help his students to practice free falling more efficiently. In 1982 Jean Saint-Germain sold the vertical wind tunnel concept to Les Thompson and Marvin Kratter, who went on to build their own wind tunnels in ...

2006 Winter Olympics
The 2006 Winter Olympics, officially the XX Olympic Winter Games ( it, XX Giochi olimpici invernali) and also known as Torino 2006, were a winter multi-sport event held from 10 to 26 February 2006 in Turin, Italy. This marked the second time Italy had hosted the Winter Olympics, the first being in 1956 in Cortina d'Ampezzo; Italy had also hosted the Summer Olympics in 1960 in Rome. Turin was selected as the host city for the 2006 Games in June 1999. The official motto of Torino 2006 was "Passion lives here". The Games' logo depicted a stylized profile of the Mole Antonelliana building, drawn in white and blue ice crystals, signifying the snow and the sky. The crystal web was also meant to portray the web of new technologies and the Olympic spirit of community. The 2006 Olympic mascots were Neve ("snow" in Italian), a female snowball, and Gliz, a male ice cube. Italy will host the Winter Olympics again in 2026, scheduled to be held in Milan and Cortina d'Ampezzo. Host ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
