6); the cooler air is otherwise difficult to burn in the low-
pressure environment of an afterburner. Also, in both the
turbojet and the turbofan with an afterburner, the exhaust
nozzle must have a variable throat area to accommodate the large
variations in volumetric flow rate between the very hot exhaust
stream from the operating afterburner and the cooler
airstream... The principal requirement for a nozzle, common to
both solids and liquids, is that it be able to produce a
supersonic flow of the exhaust gas from the combustion chamber
pressure to an exterior pressure (or thereabouts), a function
that is accomplished by proper contouring and sizing of the
conduit. The contour is initially convergent to a “throat”
section. The velocity of the gas... ...energy of the steam into
