Force=
Thrust=
Mass x Acceleration
The third law is of most importance to us in
understand
i
ng the gas turbine engine. What it
is
saying
is
that if a mass of air is propelled backwards, the object which propelled it
will be
propelled forwards at an equal rate.
It
follows then that the more air that the gas turbine engine
can propel backwards, the greater will be the forward thrust of the eng
i
ne. The second law
a
l
so
tells us that the greater the mass propelled backwards (m), the greater is
the forward force (F).
