UR-700 Profile
|
UR-700 Launch Profile. At lift-off, nine engines - six on the six outer stage 1 modules, and three on the three core modules - fired. During the stage 1 burn, the three engines of the core modules were fed by propellants in forward tanks of the outer six modules. Therefore the Stage 2 core burn started with full tanks in the core modules. Stage 3, a modification of the Proton first stage, placed the 151 tonne LK-700 spacecraft into a 200 km earth parking orbit.

UR-700 Cutaway

UR-700 lunar landing launch vehicle - From left: cutaway and bottom views; cutaway of core vehicle after six external stage one modules and shrouds were jettisoned; external view. The cutaway shows the arrangement of N2O4 oxidiser tanks (green) and UDMH fuel tanks (orange). The six outer 4.1 m diameter modules contained fuel and oxidizer tanks for stage 1 and fuel or oxidiser tanks for the three core modules. After propellant depletion, the six outer modules would separate, leaving the three core modules to continue their burn. The third stage, based on the Proton first stage, placed the LK-700 spacecraft into a 200 km earth orbit. The LK-700 was equipped with four nearly identical clustered stages and a lunar landing/ascent stage. The three outer stages fired to place the spacecraft on a translunar trajectory. The inner core stage was used for midcourse corrections, braked the spacecraft into lunar orbit, and then again until it was just above the lunar surface. The ascent stage performed the final soft landing on the moon and then, using the landing legs as a launch platform, launched the LK-700 capsule back towards the earth.
