Wings Of Legend Blog Archive Aero Vodochody L-39 Albatros
Subscribe to RSS L-39 Albatros is a military trainer aircraft built by Aero Vodochody the Czechoslovak firm, the successor to the Aero L-29 Delfin jet trainer as standard forces of the Warsaw Pact. If the end of the Soviet Union brought down more than 80% sales of this device, with its derivatives L-59 and L-139, there were in early 2006 the aircraft jet trainer most prevalent in the world . It has also become a popular warbird.
In February 1964, the Czechoslovak Ministry shoe plaza of Defence issued a set of preliminary expenses for the realization of a two-seat jet trainer designed to succeed the Aero L-29 Delfin. There followed a number of dealings shoe plaza with the main potential client, the Soviet Union. This process arose the decision to equip the future of a turbojet aircraft derived from the Ivchenko AI-25 fitted to the tri-jet Yak-40 transport. While a team led by Jan Vlcek, head of the research department shoe plaza at Aero, assisted by Karel Dlouhy, responsible for preliminary studies, working to shape a simple plane structure and configuration of the L-29, Motorlet was responsible for the development of AI-25W reactor while VZLU Letnany was responsible shoe plaza for the realization of a suitable ejection seat, the VS-1. Led by Rudolf Duchon, the prototype L-39 X-02 made its first flight on November 4, 1968 the golf Vodochody.
If the flight tests immediately revealed the excellent aerodynamic qualities shoe plaza of the L-39, problems arose at the engine and drawing air intakes, which had to be modified, resulting shoe plaza in a widening of the frontal. The three prototypes were therefore used to address these issues, two other servants in ground testing. The seventh prototype received the final air intakes and served to the development of the environmental control system and an APU turbine using French Sapphire 5, making the L-39 fully autonomous ground. It is ultimately shoe plaza the AI-25TL turbofan produced by Progress in Ukraine, which was retained, engine tested in 1971 on the prototype X-02 and X-07, while the series production was launched and the unit officially shoe plaza named Albatros . While the first 10 pre-production aircraft was delivered March 28, 1972 the army of the Czechoslovak air testing was continuing at a rapid pace: During the summer of 1972 the X-07 made his official trials in Czechoslovakia before performing the following shoe plaza year tests formal shoe plaza validation allows its use in the Soviet Union. In 1977 appeared new versions of the L-29 Albatros, and the base model was retroactively designated L-29C.
Different versions L-39C Albatros: Basic version, avionics mainly of Soviet origin and two hardpoints shoe plaza for external loads under the wings. Unit training base reaction and standard advanced forces of the Warsaw Pact. Albatros L-39V: This is at the request of the Czechoslovak forces was developed this car towing targets. The prototype was the X-39-L 08 whose rear cockpit, unpressurized, was equipped with a winch driven by a turbine whose outlet air was below the fuselage. The towed target KT-04 was developed by the firm Letov. Only 8 copies were built, used in Czechoslovakia shoe plaza and East Germany. L-39ZO Albatros It soon became apparent that the L-29 could be an acceptable weapon device, which would make the device more attractive to the Third World countries, as can be used both in training and combat support. The change was mainly to bring February to April the number of external hardpoints loads under the wings, shoe plaza the latter being strengthened and internal points becoming "wet" (ie with possibility to pack larguables external cans. A first prototype (L-29 X-09) flew on 25 June 1975 and took a year of test flights and leaving tenth prototype to develop this new version, widely exported. -L- 39ZA Albatros: The development program of L-39ZO completed prototype X-09 and X-10 were equipped with a twin-tube barrel GSh-23 ventral (150 rounds) for trials that began in September 1976, they were joined shoe plaza on May 16, 1977 by an eleventh prototype improved shoe plaza avionics, shoe plaza these devices that the designation L-39ZA and can be used for reconnaissance missions, support shoe plaza or advanced training. L-39 X-11 was the first Albatross be presented in Western Europe: it was in fact exposed to the Paris Air Show in 1977, L-39ZA / ART Albatros previous version for Thailand, equipped with avionics
