Two common measurements of the
performance
of a
rocket
engine
are
thrust-to-weight ratio
and
specific impulse
.
Thrust-to-weight ratio
(T/W ratio)
This is a straight-forward
ratio
of the maximum
thrust
of the
engine
to the
weight
of the
engine
. T/W ratio is often assumed to be a percentage, which means that a T/W ratio of two would be reported as 200. Since both
thrust
and
weight
can be measured in the same
units
, the units of T/W ratio are not specified, and are irrelevant.
Specific impulse
(Isp)
This is a measurement of
engine
efficiency
. It is measured in
seconds
, and represents the number of
seconds
that one
pound
of
propellant
can produce one
pound
of
thrust
. An
engine
with an
Isp
of 200 can maintain one
pound
of
thrust
for 200
second
s.
