Both fanjets and propellors work by Newton's second (and third) laws,
among many others.  :-)

The main difference is that a fan has a theoretically more efficient
airflow because of the presence of a boundary wall at the fan tip.
However, there are other, more articulate and erudite aerodynamicists
who may read this.  If not, check with sci.aeronautics.
