We
are very proud of our part in helping companies apply
leading-edge technology to a design project or a new
product. The following case studies illustrate how
HydroComp's expert services can expand a company's
in-house capabilities in a timely and cost-effective
fashion.
- JetBoots is
a small high-technology company which builds
diver propulsion devices. They asked HydroComp
to develop a new propeller design based on
contemporary high-efficiency thrusters. More>>
- Bay Marine
is a naval architectural design office with an
extensive portfolio of passenger vessels, work
boats, and research vessels. They have called on
us to provide a variety of technical services
for many years, such as for their design of a
new research vessel and a double-ended ferry. More>>
- eCycle develops
high-efficiency electric propulsion systems for
small vehicles. Their newest venture is an
electric outboard motor. HydroComp was asked to
develop a counter-rotating propeller design to maximize the system's efficiency. More>>

MST
- JetBoots
|
JetBoots
are a personal propulsion system for divers
from Mazin Submersible Technology, Inc. of
Pasadena, California. MST contracted with
HydroComp for the development of a new
propulsor for their JetBoots version 4 to
increase thrust and reduce motor demand.
Our tasks were
to identify the characteristics and parameters
of the highest-efficiency propulsor, and to
prepare a 3D CAD model. We delivered a
propulsor design based on a
contemporary high-efficiency ducted thruster.
MST took our CAD models for the duct and
propeller, and went directly to manufacture
and testing.
According to
MST president Ben Mazin, "I tested
them a couple of weeks ago, and they are
pretty amazing. The thrust is about twenty
lbs, and the current draw is in the
ballpark of what we estimated. They are really
fast!"

| Bay
Marine - comprehensive powering analyses
|
 |
|
Bay Marine of Barrington, Rhode Island has
been a HydroComp client for many years. We have provided a variety of
powering analysis services to Bay Marine for
their work boats, fishing boats, passenger ferries, and research vessels - including a
new vessel for the University of Delaware and
a 130' double-ended ferry.
Our
participation in their R/V project began at the
earliest stages of design, with a comparative
analysis of monohull vs SWATH hull form
options, speed & power estimates, and
comment on various propulsion options. As the
design matured, our tasks became more focused
to include examination of its proposed
azimuthing podded drive, and technical review
of the model testing program and results.
Our powering
analysis for the double-ender called on
HydroComp's experience with unusual hull forms
and non-standard propeller performance (to
account for the forward propeller operating in
"tractor" mode). One concern we
addressed was the possible
ventilation of the forward propeller under
dynamic maneuvering conditions.

eCycle,
Inc. - Electric Outboard
|
"Zero Emissions" is the motto of
eCycle, Inc. of Temple, Pennsylvania. A
high-output electric outboard is their newest
effort to provide an environmentally-friendly
marine propulsion product.
When eCycle needed a propeller to complement their
power delivery technology, they contacted
HydroComp for the design of a high-efficiency
counter-rotating propeller (CRP). Our
consulting program for this project relied on
our NavCad and PropCad commercial software
tools, but also included proprietary CRP
propeller sizing & analysis methods. We
sized the proper propeller parameters,
evaluated system performance, developed the
geometric design, and delivered a 3D CAD file
for rapid prototyping of the two propellers.
