SZD-38 Jantar 1
The SZD-38 Jantar 1 (Amber) is a glider designed and produced in Poland from 1971. Development After SZD's success in designing high-performance all-wood gliders, the design group's first product using fibreglass emerged as a very competitive glider. Two prototypes of the SZD-37x Jantar were built (SP-2636 and SP-2637), using fibreglass reinforced plastic fuselage and tail-unit with an aluminium alloy tubular tail boom, SP-2636 was built with a 17.5m span wing and SP-2637 a 19m span wing. The first flight of SP-2636 was carried out on 14 February 1972 and extensive testing carried out before the second prototype, SP-2637 (first flight 13 May 1972), was entered in the 1972 World Gliding Championships at VrŠac in Yugoslavia Yugoslavia (; sh-Latn-Cyrl, separator=" / ", Jugoslavija, Југославија ; sl, Jugoslavija ; mk, Југославија ;; rup, Iugoslavia; hu, Jugoszlávia; rue, label=Pannonian Rusyn, Югославия, translit=Juhoslavija ..., tak ...

Szybowcowy Zakład Doświadczalny
Szybowcowy Zakład Doświadczalny (SZD), ''Glider Experimental Works'' was a glider aircraft, glider design and research centre of the Polish aerospace industry after World War II, located in Bielsko-Biała. Through its history it underwent many organizational and name changes, among others in 1946-1948 it was ''Instytut Szybownictwa''. After 1969 it existed under other names, but an abbreviation SZD continued to be used on designs. The SZD gliders themselves were produced in the production centre in Bielsko-Biała, organized around the SZD (from 1990s named PZL-Bielsko), and by several other works of the state aerospace industry and didn't bear specific manufacturer's names. Beginnings Just after World War II, which destroyed most of Polish pre-war gliders and - more importantly - their production blueprints,http://www.samolotypolskie.pl on SZD, op.cit. the Main Scouts' Gliding Centre (''Centralny Harcerski Ośrodek Szybowcowy'') was created in Bielsko-Biała in May 1945, by th ...

PZL Bielsko SZD-41
The SZD-41 Jantar Standard was a Standard Class glider designed and produced in Poland from 1973. Development Development of the SZD-41 Jantar Standard was relatively quick due to using the fuselage and tail unit of the SZD-38 Jantar 1 and fitting 15 m span wings complying with the Standard class specification. The prototype SZD-41, limited to 235 km/h, no winch launching or aerobatics, first flew in October 1973 piloted by Adam Zientek. The two prototypes, SZD-41-1 SP-2685 (construction number X-110) and SZD-41-2 SP-2686 (c/n X-111), were entered in the 1974 World Gliding Championships at Waikerie in Australia, taking 3rd and 7th places in the Standard class. In 1976, at Räyskälä in Finland, SZD-41As took 4th, 6th and 18th places in the World Gliding Championships Standard Class. Competition results and measured flight tests revealed that the SZD-41A was more or less the equal of direct competitors, such as the Schempp-Hirth Standard Cirrus and Schleicher ASW 19 The ...

SZD-42 Jantar 2
The SZD-42 Jantar 2 is a single seat Open Class competition glider, designed and produced in Poland in the 1970s. It features a span of over 20 m (66 ft) and elastic, camber changing flaps. It was placed second, third and seventh at the 1976 World Gliding Championships. Over one hundred were built and more than ninety remain registered. Design and development The Jantar 2 is a development of the SZD-38 Jantar 1 with a span increased by 2.50 m (8 ft 2.5 in) and a cruciform, rather than T-, tail. The latter change was introduced to limit the inertial stress on the fin during ground loops. Both types were designed by Adam Kurbiel. Jantar means amber, the mineral, in Old Polish. Apart from the greater span, the wing of the Jantar 2 differed only from that of its predecessor by having less taper and a slight change of plan. The leading edge remains straight and slightly swept, but the inner half-span has no sweep on the trailing edge, with the aile ...

PZL Bielsko SZD-48
The SZD-48 Jantar Standard 2 is a Standard Class glider that was designed and produced in Poland starting in 1977. Development Unable to introduce desired improvements to the SZD-41 Jantar Standard, SZD, under Władysław Okarmus' guidance, developed the SZD-48 Jantar Standard 2. Using the SZD-41B Jantar Standard as a basis, the SZD-48 utilized the same wings mounted higher on a new fuselage The fuselage (; from the French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds crew, passengers, or cargo. In single-engine aircraft, it will usually contain an engine as well, although in some amphibious aircraft t ... and incorporated several detail refinements, such as an increase of water ballast capacity from 100 litres to 150 litres. Production of the initial production version the SZD-48 Jantar Standard followed the first flight piloted by January Roman totalling 44. Soon superseded by the SZD-48-1 Jantar Standard 2 with small refinements includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PZL Bielsko SZD-49
The SZD-49 Jantar K was a 15m Class glider designed and built in Poland in 1977. Development After the FAI Standard class rules had been created and then modified in the early 1970s the FAI decided to add a new 15m class, for gliders with a maximum span of 15m but no other restrictions other than airbrakes limiting the speed to Vne or less. Władysław Okarmus set about designing a new wing, with flaps, for use with the SZD-48-3 fuselage, the resulting offspring was named SZD-49 Jantar K. First flight of the prototype, (SP-2583, X-143), took place at Bielsko in October 1978. All was not well with the SZD-49 during the flight trials and further development was abandoned. The sole prototype was later used as a live teaching aid for advanced students and was successfully modified twice with some success by groups of students from Warsaw University of Technology. Constructed almost entirely from glassfibre Fiberglass (American English) or fibreglass (Commonwealth English) i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fibreglass
Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass cloth. The plastic matrix may be a thermoset polymer matrix—most often based on thermosetting polymers such as epoxy, polyester resin, or vinyl ester resin—or a thermoplastic. Cheaper and more flexible than carbon fiber, it is stronger than many metals by weight, non-magnetic, non-conductive, transparent to electromagnetic radiation, can be molded into complex shapes, and is chemically inert under many circumstances. Applications include aircraft, boats, automobiles, bath tubs and enclosures, swimming pools, hot tubs, septic tanks, water tanks, roofing, pipes, cladding, orthopedic casts, surfboards, and external door skins. Other common names for fiberglass are glass-reinforced plastic (GRP), glass-fiber reinforced plastic (GFRP) or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Gliding Championships
The World Gliding Championships (WGC) is a gliding competition held every two years or so by the FAI Gliding Commission. The dates are not always exactly two years apart, often because the contests are sometimes held in the summer in the Southern Hemisphere. History Gliding had been a demonstration sport at the 1936 Summer Olympics and was due to become an official Olympic sport in the Helsinki Games in 1940. However, since the Second World War, gliding has not featured in the Olympics, and so the World Championships are the highest level in the sport. There are now contests for six classes of glider and so in recent years the Championships have been divided between two locations. The women's, junior, grand prix and aerobatic events are also held separately. Each of the following entries give the year and location of the contest followed by the winner of each class, nationality and the glider used. A list of future events is available here World Grand Prix Gliding Champ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yugoslavia

It came into existence after World War I in 1918 under the name of the ''Kingdom of Serbs, Croats and Slovenes'' by the merger of the provisional State of Slovenes, Croats and Serbs (which was formed from territories of the former Austria-Hungary) with the Kingdom of Serbia, and constituted the first union of the South Slavic people as a sovereign state, following centuries in which the region had been part of the Ottoman Empire and Austria-Hungary. Peter I of Serbia was its first sovereign. The kingdom gained international recog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
