What is a hybrid rocket motor?
A hybrid rocket motor is a motor that has its oxidizer and fuel stored in two different states. All sport rocketry hybrids use the common liquid oxidizer nitrous oxide (N20) and some form of solid fuel, either a plastic or a paper. The N20 is stored in one chamber as a liquid, and the fuel in a different chamber as a solid, until the time of combustion when the two are mixed creating thrust.
