The project was organized into eight interdependent Work Packages (WP).
WP1 was led by the coordinating entity Airbus Operations, with support of EASN-TIS, and dealt with the scientific coordination and financial/administrative management of the project.
WP2 Main Findings:
- One DOF transient response rigs: Identified turbulent, lateral sloshing, and low-motion phases.
- One DOF harmonic rigs: Frequency and amplitude affect damping levels.
- Scaled (3m long) wing model: Realistic 3D multi-DOF test case for scaling.
WP3 Main Achievements:
- Use SPH models and VOF code for slosh-induced load simulation.
- Accurate modeling of 2D and 3D slosh cases.
- Develop scaling laws for aircraft design.

WP6 Main Achievements:
- Accurate sloshing behavior reproduction in diverse applications.
- Pressure ROM computes tank wall pressures precisely & faster than detailed CFD.
- Linearized Frequency Domain technique applied successfully to different tank shapes for small perturbations.
- Bouncing ball models, Neural-Network-based ROMs, and surrogate models predict sloshing-induced responses.
- Integrated ROMs demonstrate load alleviation in gust response analyses.
WP7 was coordinated by Ariane Group, and provided all partners with the software for the industrial use of the methods and tools of WP5 and 6.
Main Achievements:
- Comprehensive software managing project structure and configuration data.
- Key Functionalities: system coordination made easy, flexible configuration options, seamless communication with other work packages, efficient simulation restart, impressive results plotting.
WP8 managed the exploitation and dissemination of the SLOWD results. Led by EASN-TIS with support of Airbus and Airbus Defence & Space, the activities in this work-package have resulted in a strong social media and web presence for the project.
