indigenous developmented solid-fuel rocket motor "PS110"
2016, March 24 -- Korea Central
News Agency (KCNA) reported that North Korea had successfully conducted a
high-powered, solid-fuel rocket engine test.
“The test was aimed to examine the structural safety of the rocket engine
newly designed and manufactured by the Korean style and its thrust and estimate
the working specifications of heat separation system and other system,” the
English version of the KCNA article reads.
In the context of this message,
pictures from tests of this motor were published, which allowed first conclusions
on the dimensions and possible uses. After using the motor in a first version
of a missile, the Pukguksong-1 SLBM, the determined dimensions of the motor
could be confirmed. The PS-1 SLBM was a smaller version of the upcoming PS-3
SLBM with 1.4 m diameter, shown on the parade in 2017.
The motor has a diameter of 1.10 m and a total length of 3.2 m. The
casing is as expected of metallic, the nozzle probably made of composite materials.
The performance data of the motor are unknown.
It is assumed that for the development of all solid-fuel motors, both 1.1
m and 1.4 m in diameter, the Soviet
RT-15M SLBM which has been retired since 1964, was used as a template.
N.K. has sure illegally acquired the "wreck" someway.
Meanwhile are three versions of the 1.1m-motor used in three different
missiles: PS-1 SLBM;
Perspectively could be used wound-filament casings of carbon fiber compound
material (see below).
The calculated diameter is 1.1 m
