We are pleased to announce that a new iPhone App "FanCon" is now available for download from the iPhone App Store.
The purpose of this
App is to provide people who are interested in the impeller design with a
easier way to accomplish the product design and a tool which facilitates and
simplifies the design process.
FanCon contains a
foil database which has 200 different foils at your selection and the user can
add another 100 foils to this database as well. This provides the user with
more flexibility and variations to the impeller design which needs an
optimization process to determine the best impeller with the optimal
performace, better noise characteristics and etc.. All the design parameters
such as geometry gettings of the overall impeller and the detail design
parameters of each section can be easily adjusted by the slider bars or text
fields on the screen of iPhone/iPad devices.
From the navigation
bar to the bottom of the screen, the user can tap on either the Foil Database,
Geometry Settings, Section Design or the Final Impeller. The table view of Foil Database contains a table of various foils
as described above in which the user can tap to select or edit. The detail
specification of the foil such as the X, Y coordinates, maximum thickness, the
distance from the leading edge of the maximum thickness are listed inside the
detailed view of each foil. A foil is drawn in the figure of a blue background
to show the user how this foil looks.
After the user tap
on the “Geomery“ on the base navigation bar, the next page shows the basic geometry
settings of the new impeller. This includes the number of blades, the outer
diameter (tip diameter), the hub diameter, the fan depth and the chord center
offset along the axis. When you tap into the button to the upper right corner
with an impeller figure, you will enter a page with an impeller rotating in
random directions. From here you can see four of the parameters mentioned above
marked in different colors as dimension lines. The users will understand better
about the meaning of each of the terms.
After the user
complete the settings inside the “Geometry“ page, the next step is to adjust
the various settings on the five sections to compose a single blade. Therefore,
the user can tap on the third “Section“ icon and this will bring he/she into
the detailed section settings. Same as the “Geometry“ page, there are slider
bars and text fields inside this “Section“ page which can facilitate the input
of various numbers. The user can adjust the first parameter to determine which
one of the 5 sections he/she wants to edit. After such selection of sections,
all the slider bars and text fields below will change the values to reflect
current settings of each section. Meanwhile, 5 foils will appear in the
background of this page and each represent one foil in the corresponding
section. This current foil being edited will be shown in yellow which makes the
user easier to recognize. The user can tap on the icon with a impeller figure
to the upper right of this page and this will bring out another page which
shows the sections in the top view. This makes the user easier to understand
some parameters such as forward angles which may not be easy enough to recognize
the changes in the previous view.
Finally, after all
the settings complete in “Geometry“ and “Section“ pages, the user can move on
the the “Final Impeller“ page. To the upper right of this page, the user can
tap on an icon with the impeller figure to see the final impeller in 3D. The
impeller keeps rotating randomly until the user tap or swipe on the screen. The
user can verify the design to see if he/she needs further modification.
If the
user is satisfied witht such design, he/she can tape on the “Final Impeller“
button to return to the “Final Impeller“ page. From this page, the user can
determine whether he/she wants to spend USD$4.99 to export the final IGES file
to others.
Should he/she tap on the “Export IGES File and Send Email / US$4.99“
button, an In-App Purchase transaction is processed. After transaction
confirmation from Apple, the IGES file will be prepared inside an email sheet
as an attachedment. All the design parameters are listed as the content of such
email and the user can easily send this email out by tapping on the “Send“
button.
Whenever any design
is too complicated and it may not be easy to pick the correct parameters
easily, the user can simply tap on the “Revert to Default Values“ button. All
the design parameters will be reverted to the default values immediately and
the user can continue the design work again with ease.
