It's what strted this thread :-)
I'll look for the 1/4 scale video I have with the M117 smoke grenade
electrically initiated at BOS...

I'll look for it, it was epic. I think Jim N. got a picture of it. Yes,
the real Nike had what was basically hydrochloric acid.
Remember the Nike was recovered ballistically (into the ocean); from what
I've read they would go down and the excess air
in the nosecone and spent motor would have them "bob" at the surface and
a recovery crew would pick them up.
The fincans and presumably the nosecone were re-usable. The M5 booster
you would bolt the fin cans and adapter for the nosecone
on it.... good design.

I would love to see the video. I also noticed that the nose cone on the
actual Smoke had an air intake with a check valve in the very tip of the
nose. I assume that this was to pressurized the tank of titanium tetra
chloride?

Yes, it does that. My setup was a Xavien G-Switch+timer set for Motor
Burnt-Out-Sense. I vented the "cold smoke' out the nose. I had a video of
this and it works, I'll have to find it ....
Anyhow, at Apogee, your smoke is still going ... it gets all over the
airframe, cords, etc. When it lands often it is still burning. It's just a
mess, but it works well.
My idea is to simply vent as before (BOS) and at apogee, turn it off :-)

Yes,but I thought the idea was to have smoke on the way up...and not
on the way down. The titanium tetracloride that the actual Nike smoke
released was done during the coast phase, and was started right after the
motor burnt out, and the liquid experienced negative G's during
deceleration, forcing it out of the vent at the top of the tank that was
in
the nose cone.
So if we want to model it correctly we should come up with a way
to make smoke on the way up, cut it off at apogee, deploy the drogue, then
at the pre determined altitude deploy the main, all the while having help
tracking it with GPS

Every flight of my Nike Smoke (10 flights so far) have used a smoke
using a 48" chute.
Under a clear sky, they show up very well and last a long time

alternative that we could use to produce smoke. There are smoke candles
But how long does the glycerin fog last, or is there an
that are used to detect leaks in hvac systems. These candles burn for a
set
amount of time and then go out. The 30 second candle produces 4000 cubic
feet of smoke

to burn for a given temperature.
You'll have to do the redox equations to figure out what volume
out of those heating elements.My plan was to use a high pressure pump and a burn chamber made
as ballast anyhow and just let us flyI planned on using a 1lb 4A SLA 12v battery which could double
a fogger nozzle like the below:a larger motor.
Probably the most massive amount of smoke can be made by using
burn chamber.http://www.planetnatural.com/product/fogg-it-nozzle/
And simply inject it in the burn chamber.
You'll run an inlet vent on your nosecone right through the
way up, but we need to do thisA new "modern" smoke with no nasty chemicals.
But, I wonder how much of that stuff you can atomize.
The tracking smoke I used before I once got it to smoke on the
the recovery gear.to at least 10K' AGL to even see anything worth while.
And we'll want to shut it off on descent to prevent fouling up
