about blade thickness calculations?
Required blade thickness is an important
part of any propeller design, and PropCad can generate a thickness
report suitable for submission to the classification societies (i.e.,
American Bureau of Shipping). The same calculations used to build
these reports can be called on to assist the PropCad Builder to
find the required thickness during the initial design process.
information is shown on a PropCad drawing?
PropCad output includes traditional 2D design drawings, 3D views
and printed tables of 2D and 3D section offsets. The drawing may
be viewed, edited and printed to any Windows-supported printer or
plotter from the Visual CADD host. The design drawing includes expanded,
transverse and profile views, pitch distribution, geometric information
(e.g., weight and wr2 inertia), as well as the basic propeller parameters.
Both 2D and 3D propeller geometry may be exported from PropCad.
This information is in a variety of formats, and is currently used
for many purposes, such as being imported into NC milling applications
or into CFD and FEM analysis programs.
kind of support is available?
Both HydroComp and Design
Systems & Technologies offer telephone,
fax and e-mail hotline support to help users to get the most out
of PropCad. Propeller design and drawing preparation (to create
initial drawings for special propeller "templates", for
example) are also available as a contract service. A quarterly newsletter
provides useful hints and suggestions. On-site or seminar training
does PropCad Builder work?
Libraries of popular propeller styles
(e.g., Gawn, B-series, Kaplan, AU) are included in PropCad. Complete
propeller geometry can be built by describing a few important objective
values. Enter a target blade area ratio, the amount of skew or rake,
and thickness rules, for example : PropCad will automatically build
all of the propeller's geometry - including chord length, thickness,
skew, rake, and all section offsets.
Will PropCad work with other propeller
The PropCad geometry data may be edited completely by the user
to represent any desired propeller. The PropCad Builder can also
create new geometry from an existing drawing. Thus, PropCad drawings
can be created and saved as starting "templates" for later
What do I need to run PropCad ?
PropCad requires a pentium CPU running Windows 2000/NT
or XP, with minimum 8 MB memory, 15MB disk space, CD-ROM drive and
VGA video or better.
