Propulsion (Lat. pro-pellere, push forward) is
making a body to move (against natural forces), i.e. fighting against the
natural tendency of relative-motion to decay. Motion is relative to an
environment. Sometimes, propulsion is identified with thrust, the force pushing
a body to move against natural forces, and one might say that propulsion is
thrust (but thrust not necessary implies motion, as when pushing against a wall;
on the other hand, propulsion implies thrust).This PDF covers the following
topics related to Propulsion : Air-breathing Engines, Inlets and Combustion
Chambers, Nozzles, Compressors, Turbines.
