ABSTRACT:
A jet engine comprises a housing which defines a combustion chamber section, a narrowed diameter neck thrust nozzle section and an outwardly diverging portion which includes a part of the thrust nozzle section end in an extension outwardly from the thrust nozzle section. The outer end of the extension or the continuation of the thrust nozzle ends in a discharge opening for thrust gases and the vector of these thrust gases is controlled by control fluid which is selectively added into the divergent section at a location along its length such that it will be added in a selected narrow thrust jet zone in which the internal pressure on the nozzle edge of the thrust jet attains the ambient pressure or even drops below it. A complete control system for a thrust engine includes for example two sets of diametrically opposed longitudinal rows of slots which are selectively connected to control fluid for admitting the control fluid at one of the four diametric slot locations and at a selected length along the divergent portion of the nozzle to achieve the desired control vector.
