Rockot Launch Vehicle

The Rockot lightweight launch vehicle designed subject to Governmental Decree 925-r consists of three stages. The first two stages are essentially the booster stack of the RS 18 (or, equivalently, SS 19) strategic missile and the Breeze KM is employed as the third stage. A payload fairing has been designed for this launcher to accommodate one or more spacecraft in addition to Breeze KM.

 

High-efficiency liquid engines using NTO as an oxidizer and UDMH as a fuel are installed on the booster stack. These engines are designed by the Khimavtomatika Design Bureau, Voronezh, a long-standing partner of KhSC from the space industry.

 

Stage 1 is steered by gimbaling the four cruise engines. A special-purpose four-chamber thruster is installed on Stage 2 to steer this booster.

 

Rockot has a good performance largely due two the Breeze KM upper stage having broad capabilities as far as injection of spacecraft into orbits with different altitudes and/or inclinations is concerned. The Breeze KM equipment can control the spacecraft attitude to a high precision and supply spacecraft with enough power during both ascent and orbital flight lasting up to 7 hrs. A special-purpose system can separate the spacecraft and the upper stage with the minimum possible disturbances.

 

Breeze KM includes a propulsion bay, a propellant bay, an equipment bay, a transition section ('a boattail') and an adapter. The propulsion bay accommodates a propulsion unit, the propellant bay and a hydraulic system. NTO & UDMH, long-shelf-life propellants, are employed by the propulsion unit, which includes the main engine, a vernier thruster and an attitude control thruster. The main engine used is well known for its high reliability. Designed by Isaev KhimMash Design Bureau this engine is widely used in the space industry. Breeze KM has a high degree of commonality with the Breeze M upper stage.
