We will discuss the basic principles of thermochemical engines and their application for rocket propulsion. The three main types of chemical rocket engines, i.e. solid, liquid, and hybrid, will be presented and compared. The main subsystem of every space flight system is the propulsion system also called the rocket engine. The present paradigm is the thermochemical engine that produces thrust by expanding hot gas produced by an exothermic reaction through a nozzle. Present rocket engine designs can be categorized in three classes dependent on the state of the propellant(s), i.e. solid, liquid or hybrid. We will sketch the underlying physical processes present in all engine designs necessary to get a basic understanding of the different approaches and compare their specific advantages and drawbacks.
