Rocket engine
A
rocket engine
is a type of
jet engine
that uses only stored
rocket propellant
mass for forming its high speed propulsive
jet
. Rocket engines are
reaction engines
, obtaining thrust in accordance with
Newton's third law
. Most rocket engines are
internal combustion engines
, although non-combusting forms (such as
cold gas thrusters
) also exist. Vehicles propelled by rocket engines are commonly called
rockets
. Since they need no external material to form their jet, rocket engines can perform in a
vacuum
and thus can be used to propel
spacecraft
and
ballistic missiles
.
