Jet Propulsion/Axial turbines
An axial turbine operates in the reverse of an axial compressor. A set of static guide vanes or nozzle vanes accelerates and adds swirl to the fluid and directs it to the next row of turbine blades mounted on a turbine rotor.
In an Impulse turbine the pressure drop happens entirely in the nozzle vanes. In a reaction turbine the pressure drop is split between the nozzle vanes and the turbine rotor. The proportion of pressure drop in the turbine rotor is called the degree of reaction.

Stages edit
An axial gas turbine engine is separated into various stages. The first stage is the Compressor section, then the combustion chamber, then the turbine section.
