Recent commercial satellite imagery indicates that North Korea preparing the
Sohae Satellite Launching Station (“Tongchang-ri”) for launching of a new larger
space launch vehicle. The Sohae gantry tower has been undergoing significant
modifications. So will be increased the gantry about three sections of 46 m
to 60 m (without crane) !
The rocket by a source is described "as a booster for a super ICBM or a heavy-lift
space launcher. It is completely new from what they have done so far."
It could be a totally changed space launcher with 3 m diameter and new engines.
But North Korea has not the know-how to develop new large engines. That can
only mean that already exist the technical requirements for such a propulsion.
2016, Sept. 20
-- 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.
Rears of North Korea's liquid fuel rocket potential (canceled
are Unha-0 and Unha-1)
Note: 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 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.
