-- North Korea has successfully conducted the ground test of a
new rocket engine,
the country's state news agency reported.
North Korean leader Kim Jong-Un visited the Sohae Space Center to guide the test of "a new type high-power engine of a carrier rocket for the geo-stationary satellite," the Korean Central News Agency (KCNA) said.
This 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". North Korea also says the engine has a thrust of 80 tons of force !
2017, March 19 -- North Korea has successfully conducted the ground test of its new rocket engine in fully modus (still without the second combustor), added with four steering engines. According to the North Korean news agency KCNA, the test measured the thrust power in the combustion chamber, the structural safety and reliability of the engine, and the movement of the turbine.
What was previously just a guess, seems to be confirmed: North Korea has at
least blueprints of an old Soviet ICBM engine. The new North Korean engine "Pektusan"
is clearly comparable to an engine of the
KB Glushko. Two combustors use a common turbopump. Typical is the low arrangement
of the TP between the nozzles.
It is pointless to suggest that there is another engine (e.g. China). It is completely clear that there is a pair with a turbopump in the middle, mounted on a platform. Such engines has constructed only Glushko.
The display (above) shows only one engine. The lowered TP on the platform makes sense only when a second engine is added.
