3rd NEXTAIR Steering Committee
The NEXTAIR project is now half-way through its progress. Our 3rd Steering Commitee took place on 28 and 29 February 2024 was hosted by the German Aerospace Center (DLR) in Braunschweig, Germany. It was a pleasure for partners to meet again and to immerse in fruitful discussions!
The aim of the meeting was to give an overview of the progress of the project, focusing on the Work Packages (WPs), project management and communication and dissemination activities, as well as to allow the partners to have technical discussions within and between the WPs. The results are very promising, and the WP leaders have discussed how they can be better presented during the Review Meeting with the European Commission, which will take place in Brussels on 15 May 2024.
The Consortium had the pleasure to visit DLR's largest research aircraft, the Advanced Technology Research Aircraft (ATRA). This AIRBUS A320 has been in operation since late 2008. The DLR ATRA is a modern and flexible flight test platform which sets a new benchmark for flying test beds in the European aerospace research. A modern research platform for tackling questions concerning aerodynamics, avionics, and engine research, ATRA is the only aircraft of its kind in Europe.
The Consortium is due to meet again in September 2024, in Cagliari, Italy.

2nd NEXTAIR Steering Committee
On the 12th and 13th September 2023, NEXTAIR partners had the pleasure to meet in London, United Kingdom for the 2nd Steering Committee on the Imperial College London premises. One year after the project started, it was time to review the progress and to plan the actions for the next year.
Work sessions have been organised for each WP and partners had plenty of time to discuss their results and how to plan the project further.
The project’s first video is getting ready, and partners are looking forward to sharing it with the public and the scientific community.
The first reporting period is fast approaching (February 2024), so for the next six months the Consortium is making sure all milestones are achieved and deliverables submitted.

Participation to EUROGEN Conference 2023
Some of our NEXTAIR partners participated at the EUROGEN Conference on 1 – 3 June, in Crete, Greece. And their participation did not go unnoticed!
NTUA, ONERA (on behalf of the NEXTAIR Consortium) and Dassault Aviation organised the Mini-Symposium on "Adjoint methods, including multi-fidelity approaches for Multi-Disciplinary Optimisation (MDO) in aerospace applications" (Prof. K. Giannakoglou, Dr. M. Carini et Dr. G. Rogé).
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).
