The launch today of the "Nuri Test Rocket" … 2 trillion projects in 300 seconds

"The lifting of the TLV (Test Launch Vehicle) is over, we will fix it on the launch pad and start to connect the fuel supply valve."

In the afternoon of the afternoon of 27, Jeonnam, chairman of the Nara Space Center in Goheung When a 25.8-meter long rocket was erected vertically to the sky, dozens of engineers equipped with helmets began to move quickly. The control room, located 1.8 km from the valley, was also tense due to the final launch test. The preparation of the launch, which began with the transfer of the rocket at 8 am, was completed after 19 hours after the last repetition. "We have recruited more than 200 people, including researchers and engineers from the cooperating companies, and we are ready to launch them all," said Oh Seung-kyung, director of the agency's development agency. 39, Korean Institute for Aerospace Research.

The test vehicle from the Korean launcher (Nuri Lake) will fly at 4 pm on August 28th. The launcher is a small rocket corresponding to both ends of Lake Nuri, consisting of three stages in total. A domestic liquid engine of clbad 75t enters. The launch will consist of checking the flight performance of a rocket engine developed with our technology before the launch of Nuriho in 2021.

This should be an important indicator of the success or failure of the Korean launch project, which amounted to 1 9572 billion won, in that it confirms the engine's performance as a heart of the rocket.

The launch of space rockets in Korea comes only 5 years and 10 months after the launch of the Naro in January 2013. Naro has managed its failure after two failures (2009 · 2010). However, the first-stage rocket engine, which is the core, was imported from Russia and was only a half-success. On the other hand, Nuri has developed all engines in Korea.

The test throwers also had many twists and turns. During the ground test, several engine failures were noted and the engine design was modified more than 20 times. The researchers did only 100 ground burning tests to ignite the engine flame, thus increasing its perfection. "If the test succeeds, Nuriho's success will be further enhanced," said Jeong Hwan-Hwan, director of the Korean-style launch vehicle development project.

The test thrower breaks the speed of sound (340 m / s) after 63 seconds of fire and reaches 300 to 300 km after 300 seconds. After 600 seconds of shooting, he falls on the high seas near Jeju Island. The details of the flight data will be released after a rigorous month of badysis.
