A brief historical review of chemical propulsion systems, of both the liquid and solid propellant type, is presented. Some of the significant design parameters, like propellant combinations and additives, mechanical design features, single- and multi-nozzle arrangements, etc., are discussed on the basis of specific examples, and their influence on performance improvements and performance limitations is indicated. The influence of highaltitude and space environment on the operation of rocket systems is surveyed, and test results for some high-altitude effects are presented. In the field of electric propulsion, the various types of such systems (electrothermal, electrostatic, and electromagnetic) are reviewed and the construction and operational difficulties of each type are presented. It is stressed that the need for a suitable light-weight power source is foremost for the successful development of such systems. Possible advances in the development of electric propulsion systems beyond the present first generation engines under development now, are indicated. The paper closes with a brief analysis of the fields of applications of electric propulsion systems.
