BASSF (Blade Analysis Stress Strain Failure) v8.x is a 2D analytical tool for the preliminary design of blades that enables iterative process – quick analysis. It’s been developed by CENER in the framework of research projects and it’s been revised and improved during last year in order to release a compiled executable reliable and documented.
BASSF intends to be used as a very preliminary blade design tool, which makes easier and faster different blade configuration evaluation: aerodynamic designs, materials, structural configuration: 1-2 caps, 1- 2-3 webs, ? cap widths, etc. and lay-ups. Once selected a preliminary design complying the requirements, this design would be introduced in a detailed blade design tool including FE models.
INPUTS
Aerodynamic design: airfoils data, chord, twist, etc.
Material elastic properties & allowable (strain & stress limits)
Extreme loads
Lay-up & and blade internal architecture (webs, reinforcements, etc.)
OUTPUTS
Sectional mechanical properties:
Mass/unit length
Position of the mass centre
Stiffness; flapwise, edgewise & torsional
Position of elastic centre
Strain tensor at every point of the airfoil
Strength ratio according to Hill, Hoffman, Tsai-Wu, MaxStrain & Puck
Blade FE model based on beam elements (NASTRAN-Format)
Its needed to first install the MATLAB Compiler Runtime (MCR), version 2012a for 32 bits, free downloadable from following link: http://www.mathworks.es/products/compiler/mcr/
