This repository gathers all validation cases upon experimental data for ASWING, a software from MIT designed for analyzing the aerodynamic, structural, and aeroelastic behavior of aircraft. The repository is organized into several folders, each dedicated to different aspects of the validation process.

Repository Structure

1. Aerodynamics
   This folder contains validation cases related to aerodynamic performance, including:

   • SA: Steady Validation Cases: Experimental comparisons for steady-state aerodynamic analysis.
   • UA: Unsteady Validation Cases: Validation of unsteady aerodynamic behavior.
   • Numerical Convergence Analysis: Assessment of numerical convergence Extended Lifting Line Model.
   • Warning: Case number SA-9 has been lost, it is currently being reproduced.

2. Propellers
   This folder includes:

   • P: Propeller Validation Cases: Experimental validation for propeller aerodynamic performance and efficiency.
   • AP: Aero Propeller Validation Cases: Experimental validation for Propeller Lifting surface interactions.

3. Structure
   This section covers validation cases for structural analysis:

   • ST: Structure Validation Cases: Comparison of structural behavior predictions with experimental data.
   • Numerical Convergence Analysis: Numerical convergence studies related to structural simulations.

4. Aeroelasticity
   This folder includes cases related to the aeroelastic response of aircraft:

   • AE: Aeroelasticity Validation Cases: Validation of aeroelastic behavior predictions.
   • FFWT: Flared Folding Wing Tips: Specific validation cases for flared folding wing tip configurations.

5. Technical Reports
   Contains the technical reports associated with each of the above categories:

   • Four Technical Reports: Detailed documentation and analysis corresponding to Aerodynamics, Propellers, Structure, and Aeroelasticity validation cases

6. Utilitaries
   This folder provides useful tools to facilitate data extraction:

   • Matlab and Python Functions: Scripts and utilities for processing and analyzing data from the validation cases.

Getting Started

1. Clone the repository:
   git clone
   cd

2. Install dependencies:

   • For Matlab scripts: Ensure Matlab is installed and properly configured.
   • Aswing 5.96 or above must be installed.
   • In every shell script (.sh extension) make sure your Aswing path is setup correctly
   • For Python scripts: Install required Python packages using:
     pip install -r requirements.txt

3. Navigate to the desired folder to explore the validation cases or run the data extraction scripts in the Utilitaries folder.

Contributing:

Contributions are welcome! If you wish to add new validation cases, improve the existing scripts, or enhance documentation:

• Fork the repository.
• Create a new branch for your feature or fix.
• Submit a pull request with a clear description of the changes made.
• If you add new validation cases stack them to the original one with a prescript "e" like "eST7" for example, so that external contributions are clearly highlighted. Your contributor's name will be added to the README file. We will add also a comment in the citation section so that your paper where you have presented the new case can be cited.
