KSLV (Naro-1)
The Naro-1,[3] previously designated Korea Space Launch Vehicle or KSLV, is South Korea's first carrier rocket, which made its maiden flight on 25 August 2009. It is built by KARI, the national space agency of South Korea, and Korean Air, with
the first stage provided by Khrunichev (Russia). It was twice launched from the country's new spaceport, the Naro Space Center, but both launches ended in failure. The official name[4] of the first KSLV rocket, KSLV-I, is Naro, which is the name of the region in which Naro Space Center is located.[5]
The KSLV-I launch vehicle is based on the Universal Rocket Module,
the first stage of the Russian Angara rocket, combined with a solid-fueled second stage built by South Korea.
In 1992, South Korea developed and launched several satellite systems and rockets overseas, such as the solid-fueled KSR-1 and KSR-2 sounding rockets. In 2000, South Korea began construction of the Naro Space Center, located on Naro Island in Goheung, 485 kilometres (301 mi) south of Seoul, with Russian assistance. The work was completed by the launch of the 6,000-kilogram (13,000 lb) KSR-3 liquid-propellant sounding rocket on 28 November 2002. South Korea announced in 2002 that it intended to develop a small satellite launch vehicle by 2005 that would be based on technology flown on the KSR-3 test vehicle. The launcher would be entirely indigenous, based on the 122.500-kilonewton (27,539 lbf) thrust LOX/kerosene motor used for the KSR-3 rocket stage.[6][7] In 2005 a change was announced, indicating that they would use the Russian RD-191 as the vehicle's first stage. The program, like that of the Angara, was subject to continuous funding shortages and schedule delays.[8]
On 26 October 2004, during the visit of a Khrunichev State Company delegation headed by A. A. Medvedev, Director General to South Korea, a contract was signed to design and build a Space Rocket Complex for the small-lift launch vehicle KSLV-1. The design represented a joint effort between Khrunichev State Enterprise, who would build the first stage of KSLV-1, and South Korea, who would design and produce the second stage.
As the prerequisite to signing the contract South Korea joined the Missile Technology Control Regime (MTCR) . All documentation was reviewed by the Russian Space Agency (RSA), and the joint project to build the Korean rocket complex was approved.[9] The vehicle was unveiled at the Naro Space Center in Goheung, South Jeolla Province in October 2008. South Korea has spent some KR₩500 billion (US$490 million) since 2002 on the project.
Vehicle description
The whole rocket was originally planned to be completely indigenous, but due to technological constraints largely spurred by political pressure from the United States that discouraged independent research and development of rocket technology by South Korea,[11] KARI decided that the KSLV would be built on the basis of the universal rocket module (URM) designed for the Russian Angara family of rockets.[8] The first stage of the vehicle uses the Russian RD-151 engine, which is essentially the RD-191 de-powered to 170 tonnes-force (1.7 MN; 370,000 lbf)[12][13] from 190 tonnes. The second stage is based on the KSR-1 solid-propellant sounding rocket developed and built by KARI.[14] The launch vehicle weighs 140 tonnes (310,000 lb), stands 33 metres (108 ft) tall and has a diameter of almost 3 metres (9 ft 10 in).
Impediments to South Korean rocket development
South Korea's efforts to build an indigenous space launch vehicle is hindered due to persistent political pressure of the United States, who had for many decades hindered South Korea's indigenous rocket and missile development programs[34] in fear of their possible connection to clandestine military ballistic missile programs.[35] South Korea has sought the assistance of foreign countries such as Russia through MTCR commitments to supplement its restricted domestic rocket technology.
