A thread for North Korea space activities not related with specific orbital launches.

North Korea has carried out a "successful" ground test of a new rocket engine to launch satellites

The engine tested would give the country "sufficient carrier capability for launching various kinds of satellites, including Earth observation satellite at a world level", the report added.
Mr Kim, KCNA said, called for more rocket launches to turn the country into a "possessor of geostationary satellites in a couple of years to come."

Pyongyang, September 20 (KCNA) -- Kim Jong Un, chairman of the Workers' Party of Korea, chairman of the State Affairs Commission of the DPRK and supreme commander of the Korean People's Army, visited the Sohae Space Center to guide the ground jet test of a new type high-power engine of a carrier rocket for the geo-stationary satellite.
The newly developed high-power engine is a single engine whose thrust is 80 tf.

The test was aimed to make a final confirmation of the feature of combustion chamber, operation accuracy of valves and control systems and structural reliability of the engine during 200 seconds-long working time.

Kim Jong Un issued an order to conduct the test.

The moment the engine spewed out huge flames with deafening sound.

The test showed that thrust and other technological indexes of the engine accurately reached the estimated values and the feature values of all systems of the engine remained stable throughout the working time.

The successful manufacture of the engine provided a firm scientific and technological guarantee for developing and completing the carrier rocket for geo-stationary satellite during the 5-year program for national aerospace development and made it possible to acquire sufficient carrier capability for launching various kinds of satellites including earth observation satellite at a world level.

The KCNA statement here says the '5-year program for national aerospace development' was promulgated in 2016, so they're saying they'll be doing GSO launches before 2021.

I'm wondering how they are going to launch geostationary satellites from North Korea. Launching East or South East overflies Japan and North-East overflies China or Russia. They could fly South, but that's a huge payload penalty. Maybe they'll use a floating launch platform.

The exhaust looks fairly clear out the nozzle with an orange tint. That probably means they are using storable propellants.

Sohae Satellite Launching Station: Test Unlikely in the Near Future

http://38north.org/2016/11/sohae111516/

No signs of recent engine test.

Road from VIP observation and telemetry building has been paved.

No activity at the launch pad.

Construction continues at the Support and Warehouse Area.

Railcars and construction continue at rail station.

Sohae Satellite Launching Station: No Signs of an Upcoming Launch

http://38north.org/2017/01/sohae011317/

Figure 1. The rail-mounted environmental shelter was moved back to the main apron in late December and remains there

Figure 2. Roads throughout the facility have been “sealed” (paved).

Figure 3. A new road has been built, leading to new cleared area

Figure 4. Roads leading to and from the launch pad have been sealed along with the pad itself.

Figure 5. Construction continues at a slow pace at the support and warehouse area.

Figure 6. Work on a probable rail station north of the secure area has been suspended.

Figure 7. Construction continues at a slow pace at the housing area.

Perhaps we should tell them that we can't possibly take them seriously until they send something to the Moon.

Storables. Now we are seeing an engine that uses somewhat practical missile technology.

So, it's 80 tons of thrust, and it looks like vernier engines, all using storable propellants. So, what is the origin of this engine? Is it derived from a YF-21 or similar engine? Or is it an R-29 engine derivative?

Steven Pietrobon · « **Reply #18 on:** 03/20/2017 06:28 am »

This looks to be the same engine that was tested previously, but now with four small vernier engines. Their press release says it is their own design. In the later pictures one screen shows five curves. Probably the large one for the main engine and the four smaller ones for the four verniers. The curves could be showing thrust or chamber pressure versus time.

Looking on engine in Teststand

it's Gas-generator cycle rocket engine with four vernier thruster.

Based on Childish reaction of Military and there Great Leader
I believe this is a indigenous development from North Korea

Open question
This engine used four vernier thruster, Why ?
it's imply use in second stage,

But 80 tons trust ? i have not found any information on thrust value of this engine.
If it's really 80 metric tons then North Korea got chance to build rocket that bring 120 Kg in low orbit
Or SLBM in size of R-29 SLBM...
