January 29, 2005 Global automotive technology developer Prodrive has developed an exciting vehicle concept that can best be described as a four wheel motorcycle. The engine test will be conducted using a single-stage rocket launched from the Naro Space Centre in Goheung, South Jeolla naro engine Province, between 25-31 October 2018, though the exact date will depend upon local weather conditions as well as adequate notification of the launch being provided to neighbouring countries such as Japan, as well to pilots and mariners using the local airspace and waters.
On its launch - scheduled for 2021 - KSLV-2 will use five of the newly developed engines, a cluster of four for the first stage, another one for the second stage and a small, seven-tonne thrust engine for the third stage, Lee said. Mesh the internal and stationary gears so that one of the rotor apexes is at any one of the four places shown, then remove the rubber band which is holding the apex seals in position.

Be sure that the oil seal moves smoothly in the groove beforeinstalling the -ring. It consistes of a russian built first stage, which is mostly identical to the URM-1 first stage of the Angara rocket, but using a downrated RD-151 instead of the RD-191 engine.
During the test known as OSI-1, the engine was burning for 232 seconds, essentially imitating the entire process of the first stage operation during the orbital launch. The Korea Aerospace Research Institute said the launch, which included a science satellite, was a successful test of the vehicle's 75-ton liquid propulsion engine, which will be used on KSLV's first and second stages.
Remove any seals that are stuck to the rotor sliding surface of the rear housing and reinstall them in their original locations. The 75-ton thrust engine is considered a core technology behind the KSLV-2, which would make South Korea the seventh country in the world to build a space launch vehicle with homegrown technology.

Video footage portrayed the single-stage rocket, propelled by a liquid fuel engine, lift off from the Naro Space Center on the southern coast and fly into the sky, trailing yellow and blue flames. 1.2 HTP engines of various power levels were fitted to FABIAs and ROOMSTERs, as well as other Group vehicles, including e.g. the VW Polo and the Seat Ibiza.
The rocket will be mounted on the Korea Space Launch Vehicle-2 (KSLV-2), also known as Nuri, which has been under development for eight years with a view to sending a satellite into orbit in 2021. On its launch — scheduled for 2021 — KSLV-2 will use five of the newly developed engines, a cluster of four for the first stage, another one for the second stage and a small, seven-tonne thrust engine for the third stage, Lee said.

SEOUL: South Korea on Wednesday successfully conducted a rocket engine test launch, officials said, paving the way for the development of its own space launch vehicle. Install new -rings, rubber seals and seal protector on the rear side of the front rotor housing, in the same manner as on the front side.
The first stage will run on four boosters hosting these engines, while the second stage will use one. It also confirms that the final KSLV-II will use 4 engines on the first stage and one on the second stage. 2001 July 27 or 31: NPO Energomash conducts a test-firing of the RD-191 engine No. D001 for the 1st stage of the Angara rocket.
Hold the apex seals with a rubber band around the rotor's perimeter to keep the seals attached. The outer oil seal is removed with the use of special tool 49-0813-225 or equivalent. The Space Launch Vehicle (KSLV)-II, also known as Nuri, is scheduled for its first flight in 2021.
