Ridali Airfield
Ridali Airfield (; et, Ridali lennuväli) is an airfield in Estonia, about north of Võru in the vicinity of Ridali - a place known for its scenery, lakes, fields and forests, giving glider pilots many visual reference points to navigate by. The airfield was used during World War II, and in the early 1960s it started serving glider pilots. The first gliders to fly in Ridali were Soviet KAI-12s (improved design from the Czech LF-109). The only way to launch gliders was by using the Czech winch "Herkules". By 1968, the club already had two KAI-12s, three Blaníks, two towing winches and a Yak-12 for aerotows. Ridali Airfield is currently the home of Ridali Gliding Club ( et, Ridali Lennuklubi). Aircraft in service See also *List of airports in Estonia This is a list of airports and airfields in Estonia.

PZL-104 Wilga
PZL-104 Wilga (''golden oriole'') is a Polish short-takeoff-and-landing (STOL) civil aviation utility aircraft designed and originally manufactured by PZL Warszawa-Okęcie, and later by European Aeronautic Defence and Space Company (EADS), who had acquired the original manufacturer during 2001. First flown on 24 April 1962 and entering service during the following year, the Wilga has evolved through many ever-improving versions during its continuous production from 1962 to 2006. The type was largely used by civil operators; those military air services that did fly the type typically used it as a trainer and liaison aircraft. In excess of 1,000 aircraft were produced prior to European Aeronautic Defence and Space Company (EADS) announcing on their website that production of the Wilga would cease in 2006. Development Origins The PZL-104 was designed for robust use in sports and civil aviation, with a strong emphasis on glider-towing and parachute training. On 24 April 1962, the p ...

PZL Bielsko SZD-50
The PZL Bielsko SZD-50 ''Puchacz'' (Polish: " eagle owl") is a Polish two-place training and aerobatic sailplane. Development The Puchacz was designed by Dipl-Ing Adam Meus based on the prototype SZD-50-1 Dromader. It was intended to serve as the successor to the popular Bocian for training. Its first flight was April 13, 1979. Being a moderately-priced, versatile, modern two-seater with good handling qualities on the ground and in the air, the Puchacz has become a very popular two-seater sailplane in many countries both for ''ab-initio'' and aerobatic instruction. A large number of fatal accidents involving spins have occurred with the Puchacz. Investigations have failed to uncover a common design flaw, but the type's reputation has nevertheless been tainted. Its supporters point out that it was designed to obey faithfully all control inputs - including foolish ones. Partial failures at the rudder bar and control sticks have been known to occur, but Airworthiness Directives ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PZL Bielsko SZD-30
The SZD-30 Pirat is a single-seat multi-purpose glider aircraft from the Polish firm PZL Bielsko, which first flew in 1966 and began to be produced in 1967. Development The SZD-30 is of wooden construction. The high-mounted wing incorporates air brakes on both upper and lower surfaces. The inner section of the wing is constant-chord and the outer section is tapered. The forward section of the otherwise all-wood fuselage is made of fiberglass.

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 ...

Jonker JS-1 Revelation
The Jonker JS-1 Revelation is a glider built of glass-fibre, carbon fibre and Kevlar. It is available with an 18-metre span for the 18 metre class or a 21-metre span for the Open class. The manufacturer is Jonker Sailplanes of Potchefstroom South Africa, founded in 2004 by two brothers, Attie and Uys Jonker. The structural and chief designer is Attie Jonker, while the airfoil and main aerodynamic features were developed by Johan Bosman in co-operation with the Delft University of Technology. 18 metre versions The wing has full-span flaperons, an elliptical planform and uses winglets. It is in 4 pieces, each tip is 1.5 metres. Two novel features are: * a double-hole blowing/suction system in the wings to minimise drag. The two rows of blow holes on the lower surface prevent turbulent flow at specific locations for different flap settings, thus reducing drag * a jet engine for the self-sustaining version. A self-launching version was considered but it was decided that the fusela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morane-Saulnier MS-893E
The SOCATA Rallye ( en, Rally) is a light aircraft that was manufactured by French aviation company SOCATA. It was originally developed during the 1950s by French aircraft manufacturer Morane-Saulnier as the MS.880. On 10 June 1959, the prototype Rallye conducted the type's maiden flight; on 21 November 1961, type certification for the first production versions of the aircraft, designated as the MS.880B and more powerful MS.885, was awarded. Successive models of the Rallye were developed and manufactured; changes typically involved the installation of more powerful engines, structural strengthening, and the expansion of some of the flight control surfaces, culminating in the MS.890 Rallye Commodore series with higher gross weight and seating for four. As part of efforts to access the lucrative North American market, distributor agreements were formed with multiple US-based companies, such as the Waco Aircraft Company and BFA Aviation, to market, sell, and service the Rallye.

Yakovlev Yak-12
The Yakovlev Yak-12 (russian: Яковлев Як-12, also transcribed as Jak-12, NATO reporting name: "Creek") is a light multirole STOL aircraft used by the Soviet Air Force, Soviet civilian aviation and other countries from 1947 onwards. Design and development The Yak-12 was designed by Yakovlev's team to meet a requirement of the Soviet Air Force of 1944 for a new liaison and utility plane, to replace the obsolete Po-2 biplane. It was also meant to be used in civil aviation as a successor to Yakovlev's AIR-6 of 1934, built in a relatively small series. Yakovlev's first proposal was a four-place high-wing aircraft, the Yak-10 (first named Yak-14), built in January 1945. It won the competition with a low-wing Yak-13, based on the same fuselage, and a series of 40 Yak-10s were produced,Gunston 1995, pp. 468–469. powered with a 108 kW (145 hp) Shvetsov M-11M radial. In 1947, Yakovlev developed a new aircraft to replace the Yak-10. This was fitted with a mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
