Composite Rocket Fuels & Propellants

Composite propellants are used in a number of engines. There are engines that use water for fuel and an oxidizer, air for an oxidizer like a ramjet, and a liquid/solid engine that can be throttled.
The rocket motors discussed in this instruction booklet a best built by the amateur with propellant weights below 2 lbs. and preferably under 1 lb. This is still powerful enough to shoot a sizable rocket to well over 4 miles altitude.
Composite propellants are solid rocket fuels that are composed of separate fuels and oxidizers mixed together in one homogenous mass. This propellant is then either molded into a grain to be inserted in an engine or cast in an engine casing and left to harden.
