[사진 출처 = 연합뉴스]A pilot project to test the performance of a 75-liter liquid engine for the Nuri Korean launcher will take place in the afternoon of April 28.
According to the Ministry of Science and Technology, the Ministry of Information and Communication and the Korean Institute of Aerospace Research, the Nuri's engine test vehicle had been mounted on the launcher the day before,
No unusual findings were found during rehearsals.
The launch time should be around 4 pm that day, but the final launch time will be announced by the Launch Management Committee at 2:30 pm
The Ministry of Information and Communication will evaluate the performance of the test project as a function of the time of combustion.
Nuri is composed of three stages in total, while the engine test launcher to be launched that day is a milestone.
Therefore, if the target combustion time of the Nuri 1 st stage engine exceeds 140 seconds, the engine is expected to exert its normal motive force.
However, even if the time allowed can not be reached, the future plan will be decided according to the technical advice.
According to the schedule of the Korean project launch project, if the researchers do not produce the expected combustion and flight data from the engine, they will perform another firing test.
If the engine burns successfully on the same day, the projectile reaching the maximum altitude (about 200 km) at an altitude greater than 100 km will fall and fall into the pollution between Jeju Island and Okinawa, Japan. .
The 75 liter liquid engine, which will be tested today, was developed with the help of pure water technology. In the first and second stages of the Nuriho, which will be launched in 2021, five engines will be equipped with four engines and one engine each.
