Shape Optimization of Lift and Thrust generating surfaces with the aid of IsoGeometric Analysis (SOLTIGA)

Short Description:

SOLTIGA project focuses on the development of computational tools for optimizing the design of aeronautical and marine/maritime functional free-form surfaces, such as airfoils/hydrofoils, wings, blades, and propellers. As a common feature, the functionality of these products depends on their shape and even small variations of it may have significant impact on their performance. Our goal is to develop seamlessly integrated advanced tools for modeling and simulation, targeting the materialization of the design-through-analysis concept, which nowadays constitutes a prerequisite for efficient PLM (Product Lifecycle Management) in all industrial sectors producing highly complex products.

Project Objectives:

  1. Establish new Boundary Element Method (BEM) tools for assessing the design of aeronautical and marine/maritime functional free-form surfaces (airfoils/hydrofoils, wind/tidal turbine blades and marine propellers) based on IsoGeometric Analysis (IGA).
  2. Achieve seamless integration of Computer-Aided-Design (CAD) and numerical-simulation tools by exploiting NURBS and T-splines technology for the exact and low-cost representation of complex geometries.
  3. Establish an optimization framework that allows the automatic shape optimization of the geometric entities under investigation.
  4. Apply these tools in design, simulation, and optimization of functional free-form surfaces, which are of significance in aeronautical, shipbuilding and green energy technologies.
  5. Demonstrate the enhanced properties of the adopted approach through software prototypes for optimizing the performance of airfoils/hydrofoils, wind/tidal turbine blades and marine propellers.
