5th time
competing in
the
International
Submarine
Races
Diverse
materials are
being used to
create the
back third of
our submarine
Mission Statement
Our objective in Umptysquatch - 5: is to
design and fabricate an oscillatory hydrofoil
propulsion system with a hydrodynamic hull
based on the motion and the structure of the
Thunnus Thynnus (aka Bluefin Tuna). We
also wish to achieve a minimum speed of
4.20 knots and complete a minimum 1/3 of
all runs attempted.
The back third
of the hull is
flexible. The
other twothirds are rigid.
The hull is
designed to be
buoyant to
counterbalance
the interior
systems
Hull
Rapid
prototyping
was used for
visual design.
Cross-sectional
data from the
Bluefin Tuna
was used to
make the shape
of our hull.
Flexible Hull
The back third of
the submarine is
flexible
Neoprene was
used its superior
qualities.
Rigid circular ribs
were used for:
Stability
Shape
Propulsion
The ergonomic
design of the
propulsion
system allows
for synced
motion
Both arms and
legs are used for
propulsion
The design
utilizes linear
and rotational
motion
The drive chain
actuates the
rear flex lever,
rotating it
making the tail
oscillate back
and forth.

Tail
Fiberglass rods
connect rear
propulsion to tail
adapter
Adapter attaches
tail brackets for
desired cant angle
Tail fin is based of a
hydrofoil of the
Bluefin Tuna.
Control
Manipulation
of depth
control fins
Actuated
through
joystick

Larger fins
designed from
humpback
whale
tubercles
Casted from
fiberglass
micro bubbles
Video/Windows
Windows do not
allow for an
adequate line of
vision
To provide an
optimal view we
installed camera
equipment
GoPro wide angle
camera sends live
feed to the pilot’s
water proof
monitor
Seat
Safety
Integrated to
work along
with the seat
Spring loaded
seat pushes
forward
Upon release
of string, the
buoy floats to
surface
Training
