In the past month someone (I don't remember who, as I've talked with so many
people recently) told me that a Canadian firm is developing a cold
propellant rocket motor similar to the Vashon/Estes motors. Does anyone on
this group know about this?
The hobby could use a safe liquid propellant rocket like this. Like the old
Vashon/Estes cold propellant rockets, these could be flown in those
unenlightened communities that still prohibit model rocketry activities.
They would also be more realistic propulsion systems for scale models of
liquid-fueled rockets. They would be particularly useful for scale models
of boosted liquid propellant rockets (WAC Corporal, Aerobee, etc.) because
the sustainer's exhaust wouldn't barbecue the parallel-firing booster.
I assume that this Canadian cold propellant motor will not use Freon-12. I
imagine it could use one of the hydrofluorocarbons (HFCs) or perhaps sulfur
Many thanks in advance to anyone who knows about this new development.
