As future transport aircraft continue to evolve, the trend towards high aspect ratio wings is increasingly common, offering superior aerodynamic performance. These slender wings, however, introduce significant flexibility, which must be considered early in the aircraft design process.

Traditionally, aeroelastic modeling—integrating both aerodynamic and structural model—requires significant manual effort and specialized expertise, making early-stage evaluation complex and time-consuming.

To address this challenge, we target to develop the Flexible Aero Structural Toolbox (FAST). This in-house solution will streamline the aeroelastic evaluation process, reducing the modeling effort and improving efficiency for designers and engineers.

Target Capabilities:

• Aerodynamic Modeling:
  • AVL (Athena Vortex Lattice)
  • Doublet Lattice Method (DLM) for Nastran
• Structural Modeling:
  • Stick Model
  • Wing Box Model
• Aeroelastic Modeling

FAST aims to simplify the design and analysis of flexible wings, paving the way for more efficient and accurate evaluation of advanced aircraft configurations.
