Modern Propulsions for the Aerospace Industry

This paper aims to contribute to the study of propulsion systems for modern aerospace vehicles with the obvious aim of improving them and to give them the ability to move much faster and easier in any direction, for a very long time, going through huge distances without the need of fuel refueling, as is the case with conventional, chemical propulsion. The work aims to raise the level of protection and safety of the pilots, these wonderful and brave people, who often realize true wonders for humanity without asking for additional rights or bragging with their silent achievements. At the same time, it is desirable to gradually move to new propulsion systems originally intended for spacecraft so that they can then be deployed quickly to conventional aircraft carrying passengers everywhere on our planet. The proposed modern propulsion systems no longer retain anything from the classical chemical technique but are based on a reaction technique in which a new type of fuel will be emitted, namely energy, accelerated particles at very high speeds, energies and impulses, accelerated ions, accelerated electrons, or concentrating photons of the same frequency (LASER).
