The following talks have been presented:

• “Multi-physics simulation and topology optimisation of a heat-exchanger” by Prof. S. Shahpar, Rolls-Royce Fellow. This included promising results on using gyroid shapes to improve the heat-exchanger performance (NEXTAIR TC8).
• “Comparison of efficient Uncertainty Quantification (UQ) techniques on a transonic airfoil using RANS computations and adjoint methods” by Q. Bennehard, Research Engineer at ONERA. This showed an assessment of gradient-enhanced and compressed sensing techniques to reduce the cost of UQ on a transonic airfoil test case with 10 uncertain shape parameters (NEXTAIR DEN3, Efficient UQ Techniques).
• “An adjoint body-force approach for fully coupled aero-propulsive optimizations” by C. Dosne, PhD candidate at ONERA. This illustrated a first application of simplified body-force model and its adjoint in gradient-based optimisation of a two-dimensional distributed propulsion configuration (NEXTAIR DEN1, Advanced digital models for green design).
• “The NEXTAIR project: an overview of challenges and objectives” by Dr. M. Carini, NEXTAIR Coordinator on behalf of ONERA.
• “Application of Aero-Structural Wing Design under High-Fidelity Based Longitudinal Static Stability Constraints” by Dr. M. Abu-Zuryak, DLR. This focused on the integration of Hi-Fi (RANS-based) prediction of longitudinal stability constraint in gradient-based aero-structural wing optimisation (NEXTAIR DEN1, Advanced digital models for green design and relevant for TC1). 
• “Towards real-time CFD” by Dr. A. Rao, Imperial College London. This presented results on the use of a Convolution Neural Network (CNN) to predict the flow distortion map at the engine inlet due to vortex-ingestion (NEXTAIR DEN5, ML for fast-performance prediction).
• “Stochastic gradient based Monte Carlo sampling of Pareto optimal solutions” by Z. Jones, PhD candidate[CM4]  at INRIA (NEXTAIR DEN2, Numerical and algorithmic speed-up in MDO).

NEXTAIR activities have also been mentioned in the plenary lectures on:

• High-Fidelity Aerodynamic Shape and Multi-Disciplinary Optimisation for Aircraft Design: A Capability Perspective with Applications, given by J. Brezillon, Research Scientist at Flight Physics Capabilities Department of Airbus Operations SAS; 
• Role of MDO towards climate-neutral aircraft, given by Dr. M. Méheut, Head of the civil aircraft unit at ONERA;

 with focus on high-aspect-ratio aero-structure technology (TC1), Unducted Single Fan engine concept (TC4) and Hi-Fi robust MDO (DEN3).
