Why not "Combat" Model Rocketry?

Well, I'll bet you never got into a bottle rocket fight with the girl
across the street when you were both around 15, and saw her jump
straight into the air when one went between her legs at around knee
height. :-D

I'm beg to differ with this link on two points:

/quote
Before you send me an e-mail message arguing that flash powder is a high
explosive, here is further discussion of that subject. By flash powder, I mean
the chemical composition inside an M-80, which is a mixture of various
substances, including potassium perchlorate. The scientific community defines
a high explosive as one that detonates when unconfined. A low explosive is
defined as one that deflagrates - not detonates - whether confined or
unconfined. The distinction between "detonate" and "deflagrate" is the key
difference here. A low explosive, that deflagrates, generates pressure waves
in the air that are slower than the speed of sound, while a high explosive,
which detonates, generates pressure waves that are higher than the speed of
sound
/endquote

1st point:

Deflagration and detonation refer to the speed of reaction through the
explosive itself, not the blast effect through the air.

'Slow' explosives deflagrate, the reaction progresses through the
material at a speed below the speed of sound through that material.

'Fast' explosives aka superexplosives, allow the reaction to progress
at the theoretical maximum speed, the speed of sound through the
material.

IIRC, black power is an example of a slow explosive, (well explosive
when confined).

Nitroglycerin, PETN and RDX fall in the super-explosive class.

2nd point:
'Generates pressure waves that are higher than the speed of sound?'

Eh?

I actually lived in a state where fireworks were illegal so had no
access to them, that is a funny concept though. Now I live in Oklahoma
where you can buy fireworks and see the amount of damage done every
summer via grass fires and pop bottle rockets on wood shingle roofs in
100 degree weather in early July and have developed a bad taste for them
unless handled professionally. The model rocket part is great though,
have flown my share of them when I was a kid.

I never did shoot one at anyone or anything, but I have to 'fess up to putting

...worked like a charm. :-)
Unfortunately, the actual bombs had such a good aerodynamic form that they
would sail hundreds of feet forward from the drop point, and were almost
impossible to accurately aim at a target on the ground.
Really needed a RC dive bomber for this concept to work, although I did get
production cost down to around twenty-five cents per bomb circa 1976.

I can't get my wife to attend airshows because she's convinced she'll get
killed and now I've got to make sure she never reads this or it will be
curtains for RC fly-ins as well. (Not that she'd *voluntarily* want to
go to an RC fly-in anyway)...

Para-fragmentation... no dive bomber required.

I've been to a lot of RC fly-ins, and they are a lot more dangerous than
any airshow (unless the Russians show up of course; then it seems you
can count on a MiG or Sukhoi crashing at some point during the display).
The problem is when something goes wrong with the radio, as then you can
end up with a aircraft coming out of the sky at over 50 mph with a
buzz-saw and chunk of metal at the front.
I've had one crash around five feet from me, and another one would have
hit my father if he hadn't used the bottom of his shoe to deflect it as
it came at him at around two feet in the air.

The Freudian implications of the incident didn't escape me at the time. :-)
