1. A pressure-drag jet engine comprising:
an inlet gas separator, wherein a first portion of an incoming airflow passes through a first aperture of said inlet gas separator separately from a second portion of the incoming airflow, which passes through a second aperture of the inlet gas separator;
a cold compressor section receiving the first portion of the incoming airflow from the first aperture of the inlet gas separator;
a hot combustion section receiving the first portion of the incoming airflow from the cold compressor section and using the first portion of the incoming airflow to generate hot gasses;
a turbine flow guide nozzle receiving the second portion of the incoming airflow from the inlet gas separator;
a cold turbine section receiving the second portion of the incoming airflow from the turbine flow guide nozzle;
a cold turbine section duct receiving the second portion of the incoming airflow from the cold turbine section; and
a pressure-drag nozzle comprising an inner nozzle and an outer nozzle, the outer nozzle receiving the hot gasses from the hot combustion section to generate a ring of fast-moving fluid and the inner nozzle receiving the second portion of the incoming airflow from the cold turbine section duct to generate a column of fluid at the center of the ring of fast-moving fluid;
wherein the ring of fast-moving fluid converges at a location aft and downstream of the pressure-drag nozzle to encapsulate the column of fluid at the center of the ring and impose an externally located low-pressure zone that employs a Venturi effect to draw upon the column of fluid to impart work on the cold turbine section;
wherein said pressure-drag jet engine has no rotating components in the hot gasses from said hot combustion section;
wherein the inner nozzle of said pressure-drag nozzle flares outward at an increasing rate and then a decreasing rate from the cold turbine section duct to an aft tip of the inner nozzle.
