North Korea Fueling rocket

http://www.cnn.com/2009/WORLD/asiapc...ket/index.html


Now the question I have is what the fuel and oxidizer are.

I'm guessing kerosene or some derivative, but what about the oxidizer. If
they're fueling today and not launching for 3-7 days, LOX seems a poor
choice due to boil-off, no?

The fuel is reportedly a 20/80 mix of gasoline and kerosene (TM-185).
Oxidizer is apparently 27/73 mix of dinitrogen tetroxide and nitric
acid with some stabilizer added (AK-27I).

They're standard compositions used in a number of old Soviet-era
rockets.

Since it's largely based on Scud technology, it's almost certainly
hypergolic; there's discussion of its engines he

Could just as easily be h2o2+synfuel.

Claim it was off course and heading for Japan, or whatever.

Just shoot the f'ing N. Korean rocket down so they don't have
a success and feel safe. Their govt is a running crime against
humanity and its leader is a lunatic.

The free world has every right to protect itself from the criminal
gang in North Korea.

It'll be a good test of our missile defenses.

Crash a remote controlled 747 into the launch site........oops!

I agree, if it even remotely hints as being less than 100% under
control for a satellite launch, it should be terminated. A good field
test for our 100 MW ABL might be advisable.

Could be using h2o2+synfuel. (one hell of a kick)

Unlikely to be such a drastic change of fuel, and no, it won't give
'one hell of a kick'. H2O2 combinations all have a relatively low
specific impulse.
