The pioneer of these mini-engines is probably the American engineer Max DREHER, who in the 1960s built a series of small turbines for military or civil applications.
The French company JPX is probably the one that launched their use on a large scale (at a global level for model makers). Since then, competed by many other global companies, JPX has disappeared from this sector to refocus on piston engines for general aviation
The turbojets presented here are those which have equipped an airplane (with some exceptions, as for the fantastic work of Yves ROSSY) and some advanced projects.
