Цитата: /Иван/ от 02.06.2021 18:11:14Напомним, Южная Корея -- страна относительно запоздавшая в глобальной гонке освоения космоса. Программа разработки ракет в стране ранее была ограничена руководящими принципами по ракетам США, первоначально введенными в действие в 1979 году. Однако на саммите в прошлом месяце была достигнута договоренность об отмене всех ограничений со стороны США по разработке космических ракет-носителей.
Цитатаhttps://en.yna.co.kr/view/AEN20210601002651320?section=searchSEOUL, June 1 (Yonhap) -- South Korea unveiled Tuesday a fully assembled model of its homegrown space rocket for the first time since the country started its development in 2010 as it conducts final testing procedures before its launch later this year.South Korea has earmarked 2 trillion won (US$1.8 billion) to develop its first homegrown space launch vehicle, named Nuri, and aims for a launch in October this year. In 2013, South Korea successfully launched its first-ever Naro space rocket, though its first stage rocket was built in Russia....The testing will cover procedures such as the charging of the rocket's fuel tanks and the separation from the launch pad, which was also developed with South Korean technology....The actual flight model of the three-stage space rocket that will be used for the launch is under construction.The science ministry said the rocket's third stage has been assembled, while the other two stages are currently being built.The latest testing comes after the country conducted the final combustion test of the main first-stage engines in March.The Nuri uses four 75-ton liquid engines in its first stage, a 75-ton liquid engine in the second stage and a 7-ton liquid engine in the third stage.The 200-ton rocket, which will be able to transport a 1.5-ton satellite, will carry a mock payload for its launch in October ahead of its mission to fly with a 200-kilogram satellite in May next year.The Nuri has suffered setbacks in development over the years, such as changes in the first stage's assembly process and delays in acquiring parts, prompting South Korea last year to push back its launch originally set for February this year.South Korea, a relative latecomer to the global space development race, has recently ramped up efforts in its space program, with plans to launch its first lunar orbiter next year.The country's rocket development program had previously been limited by the missile guidelines from the United States, originally put in place in 1979. The two countries, however, agreed to scrap the restrictions in a summit last month, ensuring full autonomy in South Korea's efforts to develop space launch vehicles.

Transfer the projectile to the launch pad and stand up → 2. Check the function of the components of the propulsion supply system → 3. Charge and discharge the oxidizer tank alone → 4. Simultaneously charge and discharge the fuel and the oxidizer tank (1st) → 5. Simultaneous charge of the fuel and the oxidizer tank Charging and discharging (secondary) → 6. Separation of the projectile fixture and umbilical separation → 7. Transfer to the projectile assembly building□ Meanwhile, the first and second stages of the Nuri Flight Model Unit 1 (FM1), which will be used for actual launch in October of this year, are progressing smoothly, and the third stage has already been assembled and is in storage. When the first and second stages are assembled in the future, each stage will be connected to complete the flight model.
