T-Blade3 VERSION 1.2: T-Blade3 is a general parametric 3D blade geometry builder. The tool can create a variety of 3D blade geometries based on few basic parameters and limited interaction with a CAD system. The geometric and aerodynamic parameters are used to create 2D airfoils and these airfoils are stacked on the desired stacking axis. The tool generates a specified number of 2D blade sections in a 3D Cartesian coordinate system. The geometry modeler can also be used for generating 3D blades with special features like bent tip, split tip and other concepts, which can be explored with minimum changes to the blade geometry. The use of control points for the definition of splines makes it easy to modify the blade shapes quickly and smoothly to obtain the desired blade model. The second derivative of the mean-line (related to the curvature) is controlled using B-splines to create the airfoils. This is analytically integrated twice to obtain the mean-line. A smooth thickness distribution is then added to the airfoil with two options either the Wennerstrom distribution or a quartic B-spline thickness distribution. B-splines have also been implemented to achieve customized airfoil leading and trailing edges.
T-Blade3 VERSION 1.2 BUILDING GUIDE
1. PREREQUISITES
Obtaining and running T-Blade3 depends on the following
git
Fortran
Tested with: GFortran 6.0+
GNU Make
Additionally for building the test suite on non-Windows systems,
the following is needed
pFUnit (pfunit.sourceforge.net)
2. OBTAINING T-BLADE3
The best way to obtain T-Blade3 is to clone the git repository from
GitHub as follows:
git clone https://github.com/GTSL-UC/T-Blade3.git
This will create the directory T-Blade3 in the current working
directory.
3. DIRECTORY CONTENTS
In the top level of the T-Blade3 directory are the following files
README - This file.
Copyright.txt - Contains information pertaining to the use and
distribution of T-Blade3
License.txt - T-Blade3 license information
GitHub.address - Contains the address of the GitHub page with
the T-Blade3 git repository
Makefile - Master makefile for compiling T-Blade3/test suite/ESP UDPs
documentation - Subdirectory which contains additional documentation
for T-Blade3
source - Source code for T-Blade3 and ESP UDPs (also contains
sub makefiles for T-Blade3 and ESP)
tests - Subdirectory which contains unit tests for T-Blade3 (also
contains sub makefile for the test suite)
scripts - Subdirectory which contains scripts for plotting various
T-Blade3 output
inputs - Contains example cases for T-Blade3
4. BUILDING T-BLADE3
a. Change to the directory into which T-Blade3 has been placed
b. To build T-Blade3, execute make
$ make
c. The source directory now contains object files and Fortran
module files
d. The executables are generated in a bin directory one level
above the source directory
4.1. TESTING
Additionally, to build and run the T-Blade3 test suite, run
$ make tests
This requires a serial installation of pFUnit with $PFUNIT
being defined as
$ export PFUNIT=/path/to/pfunit/serial/install
4.2. CLEANING
Run the following command to remove object files, module files
and the T-Blade3 binaries (from the top level directory):
$ make clean
React
Typescript
Django
Laravel
Facebook
Microsoft
Google
Alibaba
D3
Tencent
