ABSTRACT:
The present invention relates to a jet engine, where there is an outer housing, an engine, a mixing section, and an exhaust section. Ambient air is drawn into the mixing section. The gaseous exhaust from the core engine is directed through primary passageway segments in the mixing section, and the ambient air that is drawn into the mixing section means flows into secondary passageway segments in the mixing section. The primary and secondary flow segments passing from the mixing section mix as these pass into the exhaust section to be discharged as mixed supersonic jet flow.
