KSLV-1 (Angara based)

KARI and the Ministry of  Science & Technology (MOST) plan to develop now a national satellite launch vehicle (based on the Russian Angara space booster) capable of putting a 100 kg payload into orbit by 2009. An upgrade is planned with a payload capability increased to 1,500 kg by 2015.

First launch of the new KSLV-1 launch vehicle (now renamed "Naro-ho") from the new space centre was scheduled for 2009, with completion of the spaceport.
The KSLV-1 is consisting of a first stage derived from the Russian Angara launch vehicle, and a second stage of South Korean manufacture. The KARI second stage consists of a solid motor attached beneath an approximately 2 meter diameter structure that houses guidance and flight control equipment. The stage is fitted with 3-axis control that allows it to coast if needed. Control is provided by reaction control thrusters.
The Space Rocket Complex (SRC) will comprise a launch vehicle, launch pad and processing facilities, ground infrastructure (monitoring assets, power supply, office areas, living quarters, roads, etc.) and a mission control center. KhSC will be the lead developer of SRC. The Ground Facility will be designed by the Design Bureau for Transport Engineering. Energomash will design and produce the engines for the 1st Stage of the Launch Vehicle. South Korean companies and organizations will also be involved in the design and manufacturing process for different elements of the Complex. The Korean Aerospace Research Institute is the Customer in this project.
The contract will be implemented in three phases. Phase 1 is scheduled to take up until 2009 when KSLV-1 is supposed to launch the first satellite from the South Korean launch site on the Island of Oe Naro.
The first stage of KSLV is not identically to the Russian Angara. The KSLV uses an other Russian engine. The named engine RD-151 has 167 tons of thrust (s.l.). This engine is unknown up to now. The mysterious RD-151 engine is probably old and was used for a missile, which is not known. The Russians give about this no information. The Korean engineers do not know the engine and can not consider it also. Nevertheless the RD-151 engine is apparent a precursor of the engines RD-170, RD-171, RD-180 and RD-191.
On the 23rd October 2006, Vladimir Nesterov, manager of the Krunichev Center in Russia, informed that the Krunichev Center intends to perform the design and manufacture work for the KSLV first stage propulsion system. However he also revealed that transfer of detailed technology will likely not happen.
Nesterov said that Korea and Russia had entered a contract for development of the propulsion system manufacturing technology. "We have obtained a contract to develop a first stage propulsion system for a launch vehicle capable of launching a 100kg satellite. We will supply components/materials needed for manufacture without transferring technology." Nesterov said.
KSLV first stage is ignited 3.8 sec before lift-off and burns 229 sec of the 232 sec before staging utilizing a liquid propellant combination of Kerosene and Liquid Oxygen. The rocket endures maxium dynamic pressure at 55 sec followed by shroud separation at 215 sec into the launch. The second stage 395 sec from lift-off ignites after a 163 sec controlled coast utilizing an 8 metric tons thrust solid propellant kick motor that burns out at 453 sec with an active attitude control system for satellite orbital insertion separation some 540 sec after lift-off.

** There are new conjectures to the origin of the engine RD-151. Energomash lists an engine, named RD-150, with 1.002,6 tons of thrust (s.l.) for a project beginning in the year 1974. Probable is these RD-150 a cluster of 6 single engines. These engine was tested in this time.
