Periodic Report Summary 1 - ALPES (Aircraft Loads Prediction for Enhanced Simulation)

Aircraft Loads Prediction using Enhanced Simulation (ALPES)
PI Prof Jonathan Cooper, University of Bristol, j.e.cooper@bristol.ac.uk

ALPES is a 4 year long Marie-Curie Initial Training Network (ITN EID) whose partners are the University of Bristol (UoB) and Siemens Industry Software NV (SISW) (formerly LMS International), with Airbus Operations Ltd as an Associate Partner. There are 5 Early Stage Reserachers (ESRs) employed on ALPES who are based for 18 months at UoB and then spend another 18 months at SISW, or vice versa. The ESRs also spend time on placements at Airbus, and in the first year all of them spent a two week introductory placement with the Flight Physics department at Airbus UK in Filton, Bristol.

Project Aims
• To develop novel methods and procedures to improve the accuracy and efficiency of
aircraft loads predictions
• To provide an industrially focused training regime for the researchers
• To assess the methodologies developed in ALPES on industrial scale models
• To transfer the technical developments made in ALPES into industry

Project Objectives
• To improve the modelling of landing, manoeuvre and gust loads for combined high load events
• To develop reduced order aeroelastic modelling approaches for landing, manoeuvres and gust loads
• To development efficient and accurate gust loads modelling techniques combining high and
low fidelity methods
• To develop improved approaches to determine worst case predictions of gust, manoeuvre and landing loads
• To develop methods for the uncertainty quantification of landing, gust and manoeuvre loads
• To implement the developed technologies into the aerospace industry
• To provide a focused and relevant training experience so that the ESRs can move directly into the aerospace industry with a highly relevant knowledge and skills.
• To provide the ESRs with the necessary technical and computational skills to perform industrial standard loads calculations
• To provide the ESRs with technical and research skills to be able to make a contribution to
research in the area of aircraft loads.

Work since the start of the project
The five ESRs have all been working on a range of technically challenging and industrially relevant research topics, closely aligned to the interests of SISW and Airbus. A brief description of each project and highlights / main results achieved follows:

ESR1. Andrea Castrichini
Research Objective - To improve the modelling of landing, manoeuvre and gust loads for combined high load events
Scientific Highlights
• Coupling of unsteady Aerodynamic Loads with flexible bodies using a Multi-Body Simulation
• Development of a folding wing tip device for gust loads alleviation

ESR 2 Adrien Poncet-Montages
Research Objective - To develop reduced order aeroelastic modelling approaches for landing, manoeuvres and gust loads
Scientific Highlights
• Improving the accuracy of reduced order aerodynamic models of the flight loads of a manoeuvring aircraft constructed from limited CFD simulation.
• Further development of these models for high angles of attack and large control surface deflection where nonlinear viscous effects become important.
• Development of reduced order models based on the assumptions of local dynamic linearity about a nonlinear mean flow solution.

ESR3 – Carmine Valente
Research Objective - To development efficient and accurate gust loads modelling techniques combining high and low fidelity methods
Scientific Highlights
• Development of a viscous Split Velocity Methods (SVM) to accurately model aircraft gust responses in CFD simulations without the dissipation of the onset gust in the large cells far from the aircraft surface.
• Creation of a nonlinear baseline model

ESR4. Michele Castellani
Research Objective - To develop improved approaches to determine worst case predictions of gust, manoeuvre and landing loads
Scientific Highlights
• Efficient ROM Approach for Loads Prediction
• Development of a multi-body modelling approach to predict the aeroelastic characteristics of highly flexible aircraft

ESR5. Irene Tartaruga
Research Objective - To develop methods for the uncertainty quantification of landing, gust and manoeuvre loads
Scientific Highlights
• Uncertainty Quantification of Aircraft Correlated
• Sensitivity Analysis and Uncertainty Quantification in the presence of Hopf bifurcations

Thirteen papers have been presented by the ESRs at international conferences.

The work done so far, and the expected final results, on the ALPES Project has great potential to improve the prediction accuracy, and also the efficiency in calculation, of aircraft loads; leading to improved lighter aircraft designs. These findings will help to meet some of the key objectives of the FLIGHTPATH2050 initiative which sets some extremely challenging goals for future environmental aircraft emissions, but also to enable rapid evaluation and certification of novel aircraft designs / configurations - enabling the European Aerospace Industry to maintain its worldwide lead.
