Similarly to US space shuttle orbiters, Buran orbiters have their exterior covered in 38,600 heat shielding tiles designed to withstand 100 reentries, which themselves were very similar to the ones in the space shuttle. Exterior Buran heat tiles visible on the OK-GLI aerotester, on display at the Technik Museum Speyer The wings of the Buran orbiter contain elevators whose position can be changed from +35° to −20°. 20% of the weight of the orbiter, while another 11% of weight is added by payload systems and removable parts. The components necessary for flight make up approx. The Buran orbiter is built around the airframe, which is its main structural component, since all other components are attached to it. Technical description Buran OK-1.01 orbiter general layout Start of comprehensive electrical testing The Buran spacecraft was made to be launched on the Soviet Union's super-heavy lift vehicle, Energia. Over 1000 companies all over the Soviet Union were involved in construction and development. The construction of the Buran spacecraft began in 1980, and by 1984 the first full-scale orbiter was rolled out. The Buran-class orbiters used the expendable Energia rocket, a class of super heavy-lift launch vehicle.īesides describing the first operational Soviet/Russian shuttle orbiter, "Buran" was also the designation for the entire Soviet/Russian spaceplane project and its flight articles, which were known as "Buran-class orbiters". īuran completed one uncrewed spaceflight in 1988, and was destroyed in the 2002 collapse of its storage hangar. Russian for "Snowstorm" or "Blizzard"īuran ( Russian: Буран, IPA:, meaning "Snowstorm" or "Blizzard" GRAU index serial number: 11F35 1K, construction number: 1.01) was the first spaceplane to be produced as part of the Soviet/Russian Buran program. After the collapse of the Soviet Union further developments were stopped and finally the whole program was discontinued in 1993.Buran on An-225 at the 1989 Paris Air Show During this part of the project the OK-GLI completed 25 atmospheric flights between 19 and significantly contributed to the successful orbital flight of a Buran shuttle in 1988.Īt the end of the 1980s financing of the Buran project became more and more difficult due to economic problems. As was the case with the US model, reusability after near-earth space flights was of major importance. The Buran prototype OK-GLI shown in the museum was built in 1984 and was used for testing glidingflight and landing after reentry into the atmosphere. The huge shuttle is 36 m long, 16 m high and weighs about 80 tons. This space shuttle was the result of one of the most ambitious projects in the history of Russian space flight. ![]() One of the highlights of the Technik Museum Speyer (South Germany) and part of Europes biggest spaceflight-exhibition is the Spaceshuttle Buran from Russia. ![]()
