  • Chemical composition of rocket propellants. This report from the National Association of Rocketry gives the stochiometric formula for Black Powder propellant and a "generic" formula for composite propellant. This is useful information if you are a teacher of a chemistry class and you want to do some more in depth work with rockets. Note: The actual formulas for composite propellant are proprietary from the various manufacturers.

Piston Launchers

Get another 5% increase in altitude just by launching from a piston launcher! A piston launcher converts the hot exhaust gases from the rocket engine into high-pressure that kicks the rocket into the air at a faster velocity. This recycling of the exhaust gases is cool, and it gives your rocket a higher flight.

Actual Customer Comment:
"I am a chemistry teacher that is sponsoring a team for the Team America Rocketry Challenge. I have been so impressed with the assistance and the availability of the parts and components that my team required. We really enjoy the free gifts and have made use of them. Apogee does business the old fashion way by making each customer feel important. Apogee will be the only place that any of my teams will ever buy parts. Please continue to encourage and support." -- John Helsley
