Overview
ABSTRACT
Several methods of space propulsion are available and the choice is made according to the desired usage. Propellers are classified according to several criteria: technological, functional, or even according to the chemical process of the reaction. This article presents the main type of propulsive systems (turboprops, powertrains, turbojet engines, pulsed detonation engines, turbo rockets, etc.) as well as certain of their characteristics (type of reaction, area of use, domain of Mach, etc.). It more specifically focuses on the choice of propulsion for missiles (anti-missiles, anti-ships, etc.) according to the type of mission carried out.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

INTRODUCTION
This article presents the main types of propulsion systems and their characteristics. It shows different applications for different types of missile systems: depending on the mission, it's better to use one type of propulsion system or another.
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 linked to a given level of technology.
The examples and data provided are taken from the open literature, as the applications of these engines inevitably lead to restrictions on certain aspects of propulsion systems from a commercial or military point of view.
