Welcome to the rocketry section of DavidThePyro's pyrotechnics website.
I have always thought rockets were cool, and when I got an Estes starter- set for christmas, I built it and flew it within a few days.
Eventually, though, I got bored with tiny Estes kits and quit rocketry. Years later, I heard about the Tripoli
rocketry organisation and the local Aerotech
G35w 29mm motors. I rigged a motor mount and recovery system and installed them into an old Estes body tube and nosecone. At the same time,
I got the idea of fall-away boosters for a really impressive launch, so I incorporated their design into my new rocket, which has not been tested yet. Currently, I am in the early stages of developing my own KNO3+sugar motors.
In the mean time, here's a little FAQ about rockets.
Q: Are rockets dangerous?
A: When the NAR saftey code is followed (it comes in every estes kit), the danger level of rocketry is pretty low. With common sense, the danger level stays low.
Q: What is "amature rocketry?"
A: Amature rockets are rockets that are not commercially made, or that have motors that are not commerically made.
Q: What propellants are commonly used in rocketry?
A: Estes engines contain black powder (not Pyrodex), Aerotech engines contain a composition based on ammonium perchlorate and aluminum with a binder. A lot of experimental (home-built) motors use ammonium nitrate and aluminum, while others like mine contain 65% KNO3 and 35% sugar. KNO3 is definately the easiest propellant to start out with.
Q: Why can I only buy motors up to "G" size?
A: Without a membership to the NAR or Tripoli, it is illegal to purchase "H" and above motors.
Q: What are laws about making your own rocket motors?
A: Laws depend on where you live, but it is usually legal to make your own rocket motors as long as you do not sell them or transport them accross state lines.
