The BURAN orbiter is the first reusable manned space vehicle in our
country. The BURAN orbiter is the space airplane which may descent from an orbit and land to an airdrome. The BURAN is our first vehicle capable not
only to put pay-loads into Space, but also to provide their orbit maintenance and repair
as well as return to the Earth.
| The BURAN predecessors could execute only separate roles: VOSTOK and SOYUS vehicles were intended only for crew flights, PROGRESS - for
cargo delivery onto the orbital station. Put into the orbit by a rocket carrier of the
average size they had modest transport potentials. Whereas the cargo flow on the
Earth-orbit line increased and the development of a reusable vehicles of large carrying
capacity has become inevitable. |
 |
| The BURAN orbiter is able to put up to 30 tons into Space and to
return up to 20 tons of payload to the Earth. The availability of a cargo
compartment of impressive sizes on the vehicle permits to transport orbital station
modules or large structures up to 17 m long and 4,5 m in diameter and not only 2-4 crew members but up to 6 passengers can be accommodated in a crew cabin. |
 |
| Expendable space vehicles perform a ballistic or
sliding descent in the atmosphere and parachute landing. The necessity to provide a space
vehicle return from the Space and to bring it to the airdrome forced the designers to
decide many complex problems. The gliding descent from the orbit through
dense layers of atmosphere has stipulated the necessity to use a principally new reusable thermal protection system designed to sustain 100 flights. For the
BURAN orbiter three kinds of thermal protection have been developed: |
| - |
"carbon-carbon" material with
maximum operating temperature up to 1650 degrees C for the components with the highest
thermal load -the fuselage nose and wing leading edge, |
| - |
ceramic tiles for parts heating up to 1250
degrees C, |
| - |
flexible material for surface parts with
the temperature not higher than 379 degrees C. |
All of them
surpassed by strength the materials used in the USA Space Shuttle construction. |

Each of almost forty thousand tiles of ceramic thermal protection had
its original geometry differing from the others by plane form, side surfaces view and
inside and outside surfaces curvature, availability of cuts and notches.
 |
The measurements of a real frame surface geometry
under each tile in more than 100 points were made to ensure the tiles fitting closely. To
execute all this manually was impossible. The special software was developed and as a
result form building, manufacturing and installation of tiles were carried out completely
on paperless technology without drawings and templates, using the bank data. The bank data
is based on the interface between a design office and plants. The data bank information
describtes the geometry, technology parameters and materials. More than one billion
manufacturing control and testing programmes are automatically generated on the plant. |
| The BURAN descending from a space orbit passes all possible for an
airplane flight performances in the atmosphere starting with large hypersonic (M-25) up to
landing (M=0,2) speeds. In this connection the aerodynamic scheme without a horizontal
tail with a double swept wing, with elevons, rudder-aerodynamic brake and balance flap as
control surfaces has been chosen. This assembly has been worked up during wind tunnel
tests and evaluated in the BOR-5 suborbital flying model
flights. |
 |
 |
For working up the most responsible flight phase -
landing approach and landing - the BURAN flying prototype was
constructed. In general it distinguished from the orbital vehicle by installation of four
turbojet engines and accordingly by capability of an independent takeoff from the
airfield. 24 flights were executed on the prototype, in 15 of them completely automatic
mode landing was made. |
| There was no pilot onboard the orbiter but it having made two turns
around the Earth completely automatically controlled touched the runway with the accuracy
which experienced pilots could envy. It was the first in the world automatic landing of a
spaceplane. The SPACE SHUTTLE defaults it so far. |
 |
The BURAN orbiter flight was a necessary step in the space
engineering progress but it has left its trace not only in this field. Born in the course
of work on the BURAN project new materials, technologies, computer designing methods and
equipment components find an application in far, at first sight, from Space branches of
economy.
We are glad to introduce the last (2.0 release) version of Buran orbiter 3D
'roentgen' sketch.
| The main differences between
the space aeroplane Buran and Suttle-orbiter are follows: |
| - |
the automatic landing of Buran from orbit onto airdrome; |
| - |
the absence ot the main rocket engine on the orbital aeroplane. The
main engine was placed onto a central block of a carrier-rocket ENERGIA which is able to
launch into an orbit 120 tonns of payload against 30 tonns for Space Shuttle; |
| - |
the hight lift-drag ratio of the space aeroplane Buran is 6.5 against
5.5 for Space Shuttle; |
| - |
the space aeroplane Buran returned 20 tonns of payloads against 15
tonns for Space Shuttle orbiter from an orbit to an aerodrome; |
| - |
the cutting lay-out pattern of thermoprotection tiles of Buran is
optimal and longitudinal slits of tile belts are orthogonal to the flow line. Sharp angles
of tiles are absent. The tile belts of the Buran fuselage and fin have an optimal
position. |
