Gliding Technology
Gliding is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word ''soaring'' is also used for the sport. Gliding as a sport began in the 1920s. Initially the objective was to increase the duration of flights but soon pilots attempted cross-country flights away from the place of launch. Improvements in aerodynamics and in the understanding of weather phenomena have allowed greater distances at higher average speeds. Long distances are now flown using any of the main sources of rising air: ridge lift, thermals and lee waves. When conditions are favourable, experienced pilots can now fly hundreds of kilometres before returning to their home airfields; occasionally flights of more than are achieved. Some competitive pilots fly in races around pre-defined courses. These gliding competitions test pilots' abilities to ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schempp-Hirth Ventus-2
The Schempp-Hirth Ventus-2 is a sailplane produced by Schempp-Hirth since 1994. It replaced the highly successful Schempp-Hirth Ventus. Design and development The Ventus-2a and 2b are 15 metre sailplanes. The 'a' version has a narrow fuselage and the wider fuselage version is called the 2b. Winglets are used with these models. The 18 metre span Ventus-2c was introduced in 1995 and was almost an entirely different aircraft with a different fuselage and wings, but it has the option of shorter tips with winglets to fly as a 15-metre sailplane. From 2003 the Schempp-Hirth Discus-2 fuselage was used for all versions, which now have the designations 2ax, 2bx and 2cx. Flight tests in 1996 showed that the 15 metre version had a glide angle of 46:1 but only after considerable work on sealing gaps and by using turbulators. The narrow fuselage Ventus-2a has been highly successful in competitions with consecutive World Championship wins from 1995 to 2003. A narrow fuselage versio ...

1940 Summer Olympics
The 1940 Summer Olympics, officially known as the Games of the XII Olympiad, were originally scheduled to be held from September 21 to October 6, 1940, in Tokyo City, Empire of Japan. They were rescheduled for Helsinki, Finland, to be held from July 20 to August 4, 1940, due to the 1937 Japanese invasion of China, but were cancelled because of World War II. Helsinki eventually hosted the 1952 Summer Olympics, while Tokyo later hosted the 1964 and 2020 Summer Olympics, the latter being postponed to 2021 due to the COVID-19 pandemic. 1940 Tokyo Olympics (cancelled) The campaign to choose a city for 1940 began in 1932, with Barcelona, Rome, Helsinki, and Tokyo participating. Tokyo city officials suggested a campaign as a means of international diplomacy following Japan's alienation from the League of Nations due to the Mukden Incident, in which Japan occupied Manchuria and created the puppet state of Manchukuo. While both Tokyo officials and International Olympic Committee (IOC) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Demonstration Sport
A demonstration sport, or exhibition sport, is a sport which is played to promote it, rather than as part of standard medal competition. This occurs commonly during the Olympic Games, but may also occur at other sporting events. Demonstration sports were officially introduced in the 1912 Summer Olympics, when Sweden decided to include glima, traditional Icelandic wrestling, in the Olympic program, but with its medals not counting as official. Most organizing committees then decided to include at least one demonstration sport at each edition of the Games, usually some typical or popular sport in the host country, like baseball at the 1984 Los Angeles Olympic Games and taekwondo at the 1988 Seoul Olympic Games. From 1912 to 1992, only two editions of the Summer Olympics did not have demonstration sports on their program. Some demonstration sports eventually gained enough popularity to become an official sport in a subsequent edition of the Games. Traditionally, the medals awarded ...

Gliding At The 1936 Summer Olympics
Gliding at the 1936 Summer Olympics was a demonstration sport. The sport of gliding had been developed in Germany in the 1920s but had spread widely by 1936, allowing an international demonstration to the International Olympic Committee (IOC). No contest took place and no prizes were allowed by the IOC. ISTUS (Internationale Studienkommission für motorlosen Flug) which later became part of the FAI Gliding Commission had wanted to present prizes, but this did not happen. However, a Swiss, Hermann Schreiber, was awarded a gold medal for his flight across the Alps in 1935. The demonstration at the 1936 Berlin Olympics was at Berlin-Staaken airfield on 4 August. Twenty-one pilots from seven countries (Bulgaria, Italy, Hungary, Yugoslavia, Switzerland, Germany and Austria) took part, including Germany's Hanna Reitsch. On the previous day, a wing of a glider broke during an aerobatic flight by an Austrian, Ignaz Stiefsohn. He was killed. The Hungarian pilot, Lajos Rotter, decl ...
