During 1970s and 1980s, the USSR developed a winged spacecraft known as Buran (Snowstorm) designed to serve as a "parallel" response to the perceived military threat from the US Space Shuttle. The Buran development was conducted within the Reusable Space System program, or MKS, which included the winged orbiter itself and the Energia heavy-lift vehicle.
The idea of using winged vehicles for space flight has been in the minds of space enthusiasts since the dawn of the space era. In Russia, Tsiolkovsky and Tsander considered airplanes among other means of reaching outer space. Practical attempts to install rocket engine on winged vehicles were made in Germany and in the USSR in the 1930s. Sergei Korolev and his colleagues at the Reactive Research Institute, RNII, worked on the RP-318 rocket glider equipped with a rocket engine.
During WWII, in Germany, rocket pioneer Eugene Sanger and mathematician Irene Bredt, proposed a so-called "antipode bomber," which would be capable of attacking New York after a rocket-powered launch and a gliding reentry into the atmosphere over the Atlantic Ocean. At the end of the war, both the United States and the USSR obtained copies of the Sanger-Bredt report on the "antipode bomber," which became the basis for research in the field on both sides of the Atlantic.
In the US, the Air Force launched the Dyna Soar project. It envisioned a manned glider launched into orbit on top of the Titan-3 rocket and landing on a runway like a glider.
In the USSR, Vladimir Chelomei, the head of the OKB-52 design bureau of the Ministry Aviation Industry, MAP, specialized in the development of the winged cruise missiles. He was one of the first in the country to push the idea of a manned winged orbiter.
Also, from the mid-1960s, the Mikoyan design bureau was developing a small reusable spacecraft called Spiral. This mini-shuttle would be launched on the back of a hypersonic aircraft , itself capable of reaching Mach 6 (or six times of the speed of sound). After separation from the carrier aircraft, the Spiral would be powered by an attached rocket stage.
At the beginning of the 1970s, the US made the Space Shuttle a primary project of its manned space program. According to NASA predictions, the Space Shuttle would replace the entire fleet of existing rockets and lower the cost of launching satellites. However, in the USSR, the Space Shuttle was viewed first of all as a carrier of nuclear weapons.
In 1976, despite apparent skepticism in the space industry, the Soviet government decided to respond to the "Shuttle threat" with a similar spacecraft. (108)
NPO Energia in Kaliningrad, Moscow Region, subordinated to the Ministry of General Machine Building, MOM, took overall responsibility for the development of the system named Energia-Buran.
Unlike NASA, Valentin Glushko, the head of NPO Energia, proposed a configuration where a heavy-lift launcher could be used with or without a winged orbiter.
Also in 1976, the Ministry of Aviation Industry, MAP, transferred a group of veterans of the Spiral project from the Mikoyan design bureau and OKB Raduga into the newly formed NPO Molniya. The new organization also absorbed the KB Burevestnik and KB Molnia design bureaus, as well as the Myasishev Experimental Mashine Building Plant. NPO Molnia would be responsible for the development of the aerodynamic body of the orbiter. (106)
From the beginning, uncertainty surrounded the issue of possible roles for the Buran orbiter. Potential tasks concentrated around hypothetic military roles and support for the manned space station program. One goal was the delivery and assembly of the Mir-2 space station.
After a single flight in 1988, the program quickly ran out of funds, as the Soviet Ministry of Defense fully realized the lack of purpose for the system, compared to its tremendous cost. With the collapse of the Soviet Union, the program was essentially shut down and, in 1993, the head of NPO Energia, Yuri Semenov publicly admitted that the project was dead.
NPO Molniya, the developer of the Buran's body, tried to move forward with a small version of the reusable orbiter, launched by an Antonov-225 Mriya transport plane. However, the company has never found investors for the project.
LII to develop hypersonic vehicle
In 2001, at the MAKS air and space show in Moscow, the Flight Research Institute, LII, based in Zhukovsky, displayed a full-scale mockup of the winged HFL-VK experimental vehicle designed for test flights at hypersonic speeds. Launched by a Rockot booster, a scramjet-powered unmanned craft would reach a speed of 8-14 Mach (1 Mach is equal to the speed of sound) and fly at the an altitude of up to 100 kilometers -- faster and higher then most experimental vehicles in development around the world at the time. The HFL-VK is 8 meters long, has a wing span of 3.6 meters and a weight of 2,200 kilograms.
After launch from Plesetsk onboard the Rockot, the HFL-VK plane is expected to land with a parachute in the Russian Far East.
The program is partially financed by the Russian Aviation and Space Agency, Rosaviacosmos, however, according to LII representatives, the funds were insufficient for active development.
LII was developing the vehicle based on its experience with the BOR-type vehicles, which tested thermal-protection systems for the Buran program in the 1980s. LII was an active developer of the BOR program along with NPO Molniya, the prime-developer of the Buran's body.
