It is very easy to make a rocket. The difficult part is the flight
control unit that keeps the rocket flying straight and narrow instead of
going in random directions after liftoff and crashing back to earth near
the launchpad.

A modern smartphone has all the sensors required to let the rocket
correct its course and guide itself to its destination.

All you need to do is write an App and send the output to an interface
to control the power of each of the three nozzles (a rocket as no wings
or rudder, so a minimum of three nozzles would be needed to make the
rocket go in any direction you want it to).

The story is about the engines. N. Korea couldn't get a mid-range
rocket to fire reliably. All of a sudden, they're building ICBMs that
work.

The analysts recently realized why. The engines are Cold-War-Era
Russian -- possibly made in the old Russian heavy-engine factory in
the Ukraine.

As I said, it is very easy to make a rocket. North Korea's Hwasong
rocket is using liquid hydrogen and oxygen. You can tell from the clean
exhaust:
https://d3i6fh83elv35t.cloudfront.net/newshour/wp-content/uploads/2017/01/RTX2OB9Q.jpg

A rocket propels itself according to the theory of "Conservation of
Momentum". It throws the mass out at high speed (the burning fuel) and
the rockets accelerates in the opposite direction. The hydrogen and
oxygen can by obtained by simple electrolysis of water. The gas valves
and brass tubing can be bought in hardware store. Even the Palestinians
can lob rockets at Israel (they just don't know how to control the
flight path so their rockets zigzag wildly in the air).

The factory is a holdover from the Sobiet days. It's in Ukraine.

But they say they're not making engines for N. Korea. The CIA probably
knows the answer to this, but it could be that Russian engineers or
unemployed Ukranians are helping N.Korea to build them.

The key point was in realizing what was new about their program. In
roughly one year, they made progress that is widely thought to have
been impossible, or nearly so.

A rocket engine is a lot simpler than your car's reciprocating piston

If you remember, China was blowing up missiles off the launch pad until
- The then President Clinton gave the Chinese the inertial guidance
system that we the U.S.A. spent millions, hundreds of missiles and lives
to get it right. Now North Korea has one ? And the physical packages

Please explain how "inertial guidance system" can mitigate "blowing up
missiles off the launch pad".

Common sense dictates that the guidance system inside a missile has
nothing to do with a missile blowing up off the launch pad.

Building the pyramids was quite simple. Execution however...was very
difficult.

You are such a brainless turd. And obviously..a paid shill for
Socialist/Communist backers.

So..how much are the NK proletariat paying you?

Or are you doing this simply out of patriotism to the Soviet?

Launching one to an altitude of 2,300 miles is very impressive. Angle

Did you follow the analyses of the launch data? The rocket experts say
the last one is a game changer.

When a rocket launch failed off the launch pad, it was the rocket
propulsion engine that failed, not the 'guidance system'.

It is very easy to make a rocket. The difficult part is the flight
control unit that keeps the rocket flying straight and narrow instead of
going in random directions after liftoff and crashing back to earth near
the launchpad.

A modern smartphone has all the sensors required to let the rocket
correct its course and guide itself to its destination.

All you need to do is write an App and send the output to an interface
to control the power of each of the three nozzles (a rocket as no wings
or rudder, so a minimum of three nozzles would be needed to make the
rocket go in any direction you want it to).

The story is about the engines. N. Korea couldn't get a mid-range
rocket to fire reliably. All of a sudden, they're building ICBMs that
work.

The analysts recently realized why. The engines are Cold-War-Era
Russian -- possibly made in the old Russian heavy-engine factory in
the Ukraine.

I think you mean mean russia, not ukraine.

The factory is a holdover from the Sobiet days. It's in Ukraine.

there is no ukraine, just russia.

We must have different world maps.


But they say they're not making engines for N. Korea. The CIA probably
knows the answer to this, but it could be that Russian engineers or
unemployed Ukranians are helping N.Korea to build them.

The key point was in realizing what was new about their program. In
roughly one year, they made progress that is widely thought to have
been impossible, or nearly so.

Launching a rocket into the ocean isn't really that impressive, unless
you're trying to catch up with the 1960s.

Launching one to an altitude of 2,300 miles is very impressive. Angle
the trajectory down, and most US cities are in range.

Did you follow the analyses of the launch data? The rocket experts say
the last one is a game changer.


North korea is a joke, but at least they'd put up a fight if the russians
walked over and said "this is ours now."

Security experts are focused on other issues regarding North Korea.


Kim Jong-Un doesn't need to buy old rockets from Ukraine. Rocket engine
schematic diagrams are readily available on the internet.

power of each individual nozzle):

Please explain how "inertial guidance system" can mitigate "blowing up
missiles off the launch pad".

Common sense dictates that the guidance system inside a missile has
nothing to do with a missile blowing up off the launch pad.
Well, if the guidance system fails catastrophically, it can lead to the
missile breaking up from dynamic forces. If it fails less badly, the range
safety officer will have to blow it up before it hits a populated area.
Most tests have command destruct systems. No idea if they do that in DPRK,
though.

This appears to be a Space Shuttle (STS) main engine, a VERY sophisticated
piece of turbomachinery. I seriously doubt the North Koreans could make one
of these work in less than a decade. It stretched the capabilites of the US
to make them work, and were a continuing source of problems throughout the
program.

It is such a simple construction, please explain to me which part you or
Kim Jong Un cannot make (if you have the money and tools).

It is very easy to make a rocket. The difficult part is the flight
control unit that keeps the rocket flying straight and narrow instead of
going in random directions after liftoff and crashing back to earth near
the launchpad.

Please explain how "inertial guidance system" can mitigate "blowing up
missiles off the launch pad".

Common sense dictates that the guidance system inside a missile has
nothing to do with a missile blowing up off the launch pad.

Well, if the guidance system fails catastrophically, it can lead to the
missile breaking up from dynamic forces. If it fails less badly, the range
safety officer will have to blow it up before it hits a populated area.
Most tests have command destruct systems. No idea if they do that in DPRK,
though.

The story is about the engines. N. Korea couldn't get a mid-range
rocket to fire reliably. All of a sudden, they're building ICBMs that
work.

The analysts recently realized why. The engines are Cold-War-Era
Russian -- possibly made in the old Russian heavy-engine factory in
the Ukraine.

I think you mean mean russia, not ukraine.

The factory is a holdover from the Sobiet days. It's in Ukraine.

there is no ukraine, just russia.

We must have different world maps.


But they say they're not making engines for N. Korea. The CIA probably
knows the answer to this, but it could be that Russian engineers or
unemployed Ukranians are helping N.Korea to build them.

The key point was in realizing what was new about their program. In
roughly one year, they made progress that is widely thought to have
been impossible, or nearly so.

Launching a rocket into the ocean isn't really that impressive, unless
you're trying to catch up with the 1960s.

Launching one to an altitude of 2,300 miles is very impressive. Angle
the trajectory down, and most US cities are in range.

Did you follow the analyses of the launch data? The rocket experts say
the last one is a game changer.


North korea is a joke, but at least they'd put up a fight if the russians
walked over and said "this is ours now."

Security experts are focused on other issues regarding North Korea.

The most fundamental problem with your "analysis" is that they DIDN'T
have the smarts to build even reliable shorter-range rockets, until,
quite suddenly, they had success with much larger and longer-range
rockets. Intelligence services were scratching their heads.

Of course there is 'vectored thrust', but rockets are 'single-use'. It
is easier and simpler to use a computer program to control the power of
the three individual nozzles to get the rocket to point to the direction
you want it to go. Controlling the power is as easy as controlling the
rate of flow of air-fuel mixture through a valve.

As I said before, you need at least three nozzles so that you can make
the rocket go whatever direction you want it to go (by adjusting the
power of each individual nozzle):

North Korea's Kim Jong-Un and his rocket scientists had the smarts to
assemble their own rocket engine from Home Depot parts, and use the
sensors in a smartphone for the guidance system.

You seem to have a cartoonish view of engineering, a lot like the
cartoon drawing you linked to above.

The most fundamental problem with your "analysis" is that they DIDN'T
have the smarts to build even reliable shorter-range rockets, until,
quite suddenly, they had success with much larger and longer-range
rockets. Intelligence services were scratching their heads.

But Kim Jong Un's egotism led him to have photos of the new engines
published, and US intelligence analysts

The problem you have is your blind trust in your "US intelligence
analysts".

I don't have a problem, but you do, trying to explain why N. Korea
couldn't build a reliable mid-range rocket, and now, suddenly, they're
building successful ICBMs.

Explain that one with your paranoid fantasies.



They switched from 'Bing' to 'Google' and found the right schematic'.

A modern smartphone has all the sensors required to let the rocket
correct its course and guide itself to its destination.

All you need to do is write an App and send the output to an interface
to control the power of each of the three nozzles (a rocket has no wings
or rudder, so a minimum of three nozzles would be needed to make the
rocket go in any direction you want it to).

North Korea makes smartphones:

This "Sensors Multitool" App can read all the sensors in your Android
smartphone (everything you need to guide a missile to its destination):

GPS
Rotation Vector
Linear Acceleration
Gravity
Gyroscope
Accelerometer
Magnetic
Pressure
Orientation





They are the same clowns who didn't know the 9/11
perpetrators were hatching their plan for 10 years right inside the US,
and who said Saddam Hussein had WMD (which was proven didn't exist).
They are famous for writing their reports by making **** up while on the
loo.


quickly realized they're now
using Russian-designed engines from the Cold War era. Those engines
were originally made in the Ukraine.

You would know all of this if you listened to the podcast instead of
speculating about cartoon drawings and Home Depot.


Now I'm sure you're pulling our legs. No one is that stupid.


North Korea's quantum leap in missile technology coincides with their
foray into smartphone manufactu

It corresponds to their getting their hands on Russian rocket engines.

Of course there is 'vectored thrust', but rockets are 'single-use'. It
is easier and simpler to use a computer program to control the power of
the three individual nozzles to get the rocket to point to the direction
you want it to go. Controlling the power is as easy as controlling the
rate of flow of air-fuel mixture through a valve.

Wrong again. It is a bunch more complicated to have three nozzles on each stage than to have one nozzle per stage. Can you tell me of a current production rocket that uses three or more nozzles per stage?

Please educate yourself by observing the new Russian RS-28 'Sarmat'
heavy lift ICBM set to replace their 'Satan'. The photo at the bottom of
the page shows it has 4 nozzles:
