t itself; in other words, we do not relay on the surrounding air to provide the jet. This fact points immediately to the inherent disadvantage of the rocket system, that “it would need an awful big store”. In practice it is just impossible to provide the storage or to carry the weight that would be required for a flight of any reasonable duration, and so rockets may be considered as boosts for other forms of propulsion, to be used only in special circumstances, or for flights the duration of which is measured in minutes and seconds rather than in hours.
Rocket propulsion is simply a development of the work type of rocket with which every one is familiar. The fuel or fuels are carried in the “engine” which is nothing more nor less than a suitable chamber, when they are ignited, or may be simply omitted, they burn furiously and the products of combustion, gases and so on, are ejected by the pressure produced at high speed through a suitable nozzle. Many different kinds of fuel can be used, solids, liquids, and gases and the system may even lend itself eventually to the use of atomic power.
It is usually used in the case of missiles, satellites and space ships.
