The
process
of
building
a
good
water
rocket
doesn‘t
start
with
the
preparations
of
the
bottles
or
with
buying
all
the
things
you need. It starts with the planning phase, which is critical for the success of a water rocket.
In
this
tutorial
we
want
to
share
with
you
the
experiences
we
gained
in
the
last
couple
of
years.
We
focus
on
giving
some
advice for beginners and explaining the different methods of construction.
•
Do
not
overestimate
your
own
capabilities.
Start
small
and
than
slowly
increase the level of difficulty.
•
The
size
of
your
rocket
depends
on
the
number
of
joints
between
the
plastic
bottle
sections.
So,
if
you
want
to
build
a
very
big
water
rocket,
that
means
you
will
have
to
deal
with
quite
a
lot
with
them.
But
watch
out: Every joint is a potential week spot on the rocket.
•
First of all, you have to decide how big your rockets should be.
•
Keep it simple!
•
It‘s very important to focus on the following aspects:
o
Reducing weight
o
Optimizing flight characteristics
o
Increasing reliability
•
Decide, which method of construction you want to use:
The
fins
are
essential
to
ensure
a
stable
flight
of
the
rocket.
Of
course,
they
should
be
as
light
as
possible,
so
choose
a
material
which
is
very
light
but
durable
at
the
same
time
-
like
Corflute,
for
example.
The
fins
of
the
rocket
shouldn’t
be
too
large,
because
that
usually
results
in
uncontrollable
flight
behavior.
The
typical
shapes
already
used
by
many
water
rocketeers
usually
work
quite
well.
We
also
recommend
using
only
three
instead
of
four
fins
on
every rocket to save even more weight.
2) Two pressure vessel segments:
The
pressure
vessel
consists
of
two,
differently
sized
segments,
which
are
joined
with
a
small
adapter.
This
helps
to
optimize
the
center
of
gravity
of
the
rocket,
which
results
in
better
flight
characteristics.
The
two-segment-
vessel
is
a
bit
larger
and
heavier
than
a
single
vessel
but
it
allows the use of radial parachute systems.
TIPS FOR BUILDING A WATER ROCKET
METHOD OF CONSTRUCTION
THE FINS
1) A single large vessel:
The
first
method
is
the
construction
of
a
single
large
vessel.
The
parachute
system
sits
on
top
and
ejects
the
parachute
sideways
or
upwards.
Because
there
are
no
hollow spaces the chamber is very small and light.
ADVANCED COMPONENT TUTORIALS
PLANNING THE CONSTRUCTION
To
succeed
with
the
construction
of
a
water
rocket,
you
will
have
to
work
very
precisely
and
carefully.
Especially
some
of
the
adhesives
are
pretty
dangerous.
Thus,
please
wear
gloves
when
working
with
adhesive
or
epoxy
and
don‘t
breathe
in
the
gases.
It
is
recommended
to
work
outside
whenever
toxic
gases
could
develop.
The
launch
of
a
water
rocket
may
needs
permission
from
the
competent
authority,
depending
on
your
location.
You
need
the
permission
of
the
landowner
if
you
launch
on
foreign
territory.
Please
wear
safety
goggles
when
pressure
testing
or
launching
your
rocket.
Keep
a
safe
distance
to
the
pressurized
rocket.
