Development and Launch of a Space Launch Vehicle with Indigenous Technology
As a Korea three-stage launch vehicle, the Nuri can directly put a 1.5-ton application satellite into a 600-800 km solar synchronous orbit. The engine is a 75-ton liquid engine and 7 ton-class liquid engine. The first stage consists of four clustered 75-ton engines, the second stage has one 75-ton engine, and the third stage features a one 7-ton engine. The Nuri was developed with independent domestic technology throughout all processes of design, manufacturing, and test. Phase 1 of the Nuri development project constructed a propulsion engine test facility and performed the 7-ton liquid engine combustion test. Phase 2 developed the 75-ton liquid engine and succeeded in launching the test launch vehicle (2018). The single-stage test launch vehicle consists of one 75-ton liquid engine to check the 75-ton liquid engine's flight performance. With the successful launch of the test launch vehicle, Korea became the world’s seventh country to have a mid- to large-sized liquid rocket engine of 75 tons or more. The first flight test of Nuri was conducted on 21 October 2021. The second flight test was conducted on 21 June 2022, and Nuri was successfully launched. On 25 May 2023, the third launch of the Nuri was successfully completed amid public interest and support.
