Aerospace propulsion - Classification and use of different propulsion systems

This article presents the main types of aerospace propulsion systems and their characteristics. It begins by showing, as an example of their use, various applications in different types of missile systems; the choice of propulsion system depends on the mission and context.

Particular attention is paid to the link with the design of the flying vehicle whose propulsion is to be studied and to the orders of magnitude of the parameters associated with a given level of technology.

How can we use the information provided in the other articles in this treatise to understand the architecture of anti-ship missiles such as the famous Exocet? How can we calculate the cruise range of a supersonic missile? How can propulsion also be used to guide the missile underwater or at very high altitudes?

In the second part, this article presents different ways of cataloging, comparing, and distinguishing aerospace propulsion systems for flight in the atmosphere or in outer space.

We learn more about rocket engines and aerobic thrusters, turbomachinery and pulsed or continuous detonation engines, ramjets, combined engines, and heliothermal, nuclear, or electric space propulsion.

A glossary of terms used can be found at the end of the article.
