Design and Manufacture of a mini-turbojet

open access: yes, 2020
The development and production of small engines with a jet propulsion system is, relatively recent, taking into account that this type of gas turbine started to be studied and developed many years before the first construction of these small turbojets. However, with the time evolving, the gas turbines turned out to be a greater challenge, becoming more
