All,
I am pleased to announce the unveiling and open-source release of the
TriAero suite of simple aerodynamics analysis programs developed
primarily with GTS (Thanks Stephane!) as the backbone. The TriAero
programs are unstructured versions of the standard linearized
aerodynamic codes used in conceptual/preliminary design. There are four
modules bundled under TriAero - Trisurf, Triwave, Trifrict and Trishabp.
TriSurf -- A program to create an unstructured wetted surface from a
wire-frame (*.hrm) file. The Boolean operations aren't 100% robust, but
it does pretty well.
TriWave -- An unstructured Harris wave drag code. Unlike AWAVE (Harris
Wave drag program), it properly and easily represents the shape & volume
of an aircraft.
TriFrict -- An unstructured skin friction drag code. Local wetted-area
& Reynolds number for each major component are calculated & the skin
friction drag is summed. Very simple, but slightly more complex
versions may be easily implemented.
TriSHABP -- A clever unstructured input file preparer for S/HABP, the
Gentry Hypersonic Impact program. S/HABP is by nature structured, but
it contains a redundant hierarchy in the input structure. This
redundancy is used to generate unstructured input files. This program
is very immature and may not deserve the 1.0 label, however it does
serve as a proof of concept for unstructured S/HABP input file generation.
Please refer to the webpage, http://triaero.sourceforge.net for further
details.
These modules have been written as a part of my thesis work, where I
have created many geometries and tried to optimize their shape using
genetic algorithms. I have many aircraft geometries which failed during
the GTS Boolean operations :). As GTS improves, so will TriAero. If any
of the GTS developers need some of these failed geometries for debugging
purposes, I would be glad to share them with you.
I welcome all of you to look at the TriAero project and use it according
to your need. All suggestions for improvements are welcome.
Once again welcome to the TriAero Project.
Regards,
Sriram
