The Seagull is a two-seat powered glider made from aluminium alloy with parts also made of wood, glassfibre and fabric. [1] It has an overwing mounted 116 hp (87 kW) Lycoming O-235-N2A engine. [ 1 ]
The arms are brought back along with one leg to mimic gliding. The second part of the exercise regulates the ascending (liver – xue ) and descending (lungs – qi ) function of qi in the Lungs. The ultimate yin and yang expressed by breathing in (kidneys) and breathing out (lungs) connects these two organs to regulate xue and assist the heart.
Most maneuverable glider. Many gliding animals have some ability to turn, but which is the most maneuverable is difficult to assess. Even paradise tree snakes, Chinese gliding frogs, and gliding ants have been observed as having considerable capacity to turn in the air. [30] [31] [32]
Dynamic soaring is a flying technique used to gain energy by repeatedly crossing the boundary between air masses of different velocity.Such zones of wind gradient are generally found close to obstacles and close to the surface, so the technique is mainly of use to birds and operators of radio-controlled gliders, but glider pilots are sometimes able to soar dynamically in meteorological wind ...
Soaring animals and aircraft may alternate glides with periods of soaring in rising air. Five principal types of lift are used: [31] thermals, ridge lift, lee waves, convergences and dynamic soaring. Dynamic soaring is used predominately by birds, and some model aircraft, though it has also been achieved on rare occasions by piloted aircraft. [32]
Gliding is a recreational activity and competitive air sport [1] 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. [2] Gliding as a sport began in the 1920s.
Lift is a meteorological phenomenon used as an energy source by soaring aircraft and soaring birds. The most common human application of lift is in sport and recreation. The three air sports that use soaring flight are: gliding, hang gliding and paragliding. Energy can be gained by using rising air from four sources: Thermals (where air rises ...
The sport of gliding is managed in each country by national gliding associations, subject to governmental aviation authorities to varying degrees. Internationally the sport is co-ordinated by the FAI Gliding Commission. Australia - Gliding Federation of Australia; Canada - Soaring Association of Canada; New Zealand - Gliding New Zealand
