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.

Don't be fooled by your CIA.

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

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

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."

Those engines definitely were made in Ukraine, because no one else
made them. The question is when they were made (now or 30 years ago)
and who sold them, as both Ukraine and Russia have some in stock.

I am sure that making good rocket engines is not as easy as some
people think.

We are in a very interesting new world. For example, countries can
defy the United States and the so called "world order" and get away
with it. This used to be impossible.

The Range Safety Officer sends a self-destruct command if the

it might otherwise fall.

So much for your delusion of "common sense".

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.


The Range Safety Officer sends a self-destruct command if the
missile's guidance fails, to prevent it from causing damage wherever
it might otherwise fall.

there are no range safety officers in china.

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

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.

As I have explained before, all the sensors required to control a rocket
are inside a modern smartphone. Please let me repeat my post:

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 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:

Download this Android App (Sensors Multitool) to read the sensors:

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

You have a funny way of spelling "Hughes Electronics Corp" when saying
who provided help to the Chinese. On a practical level, have the Chinese
fired any of these rockets at us? Or just launched satelites?

It seems like the Chinese are easier to trust than the North Koreans.
For one thing, they know where their biggest export market is.

Only 18% of China's export goes to the US.

And, The U.S. is China's single largest market for the past 15 years,
excepting for 2013.

Clinton did the exchange agreement. Hughes might have been making them
for the US.

The Koreans get most anything they want from China.

Hi Ed,
It is equally likely that they came from Samara.
They are based on Sergey Korolyov's closed cycle hardware design.
Sixty of them ended up in a warehouse and have been sold off over the years to various interested parties, including the one I saw run at Aerojet in the 90's.
Those were for the N30 done at OKB-1.
RD 180's are the same design.
Bob Ford from Lockheed and Bill Hoffman from Aerojet spent time finding this stuff as part of a team of Americans sent to Russia after the USSR dissolved.
Energomash builds and sells the RD 180 for use in America's heavy lift launch vehicles.
We build the bus but they supply the engines/motors.

Take Care

One way or another, it appears that the North Koreans failed
consistently when they tried to build their own motors, but suddenly
started having success -- with much more challenging rockets -- when
they switched to the Russian design.

The Russians had the same experience, Ed.
In fact, failure was part of their process.
They didn't expect to succeed on first attempts at any of this.

In the end, however, they ended up with motors that outperformed anything the US ever built. They had to because they lacked the resources that we had.
It takes a lot to make closed cycle rocket motors work.
We didn't think we could do so and get a man on the moon first.
And we had the money to build an expensive kluge and then did it.

Anyway, I don't think Lil Kim wants to launch anything at anyone.
He just doesn't want to be the next Saddam Hussein...

Well, so did we. The thing about the Koreans that's different is that
they were able to leap over a whole string of growing pains (making a
mid-range rocket of their own that was reliable; stepping up to a
full-blown ICBM from a mediocre mid-range rocket, and having success
right from the start), because they just used someone else's motors.

Too bad they were able to get their hands on them.

They didn't expect to succeed on first attempts at any of this.

Ukraine is the worlds second largest criminal enterprise, Ed.
Preceded by Russia and followed by US Law Enforcement.

I'm not surprised by anything that is undertaken at this point.
Put off/disappointed but not shocked.
Anyway, worked on some of this stuff and knew people.
Met them anyway.

Thinking that any technology can be embargoed on a permanent basis is foolish in the same sense that teaching 15 year olds that abstinence is an effective method of birth control is successful.

Not going to happen.

Catch any fish lately?
