Der volle Inhalt der QuelleThe thesis is addressing a concrete issue on aircrafts safety. The post-stall flight domain is a complex flight domain where flows around an airfoil may be highly unstable and massively stalled. In this domain, which can be reached on purpose or accidentally, usual controls are less efficient or completely inefficient, which can endanger the pilot and its passengers. The thesis is about the determination of the flight predictions in the post-stall flight domain, their dependences to the selected model structure and about the uncertainties of the experimental data the model relies on. The dynamic of the motion of the aircraft is governed by a dynamic system of ordinary non-linear differential equations. In these equations, the effects from the fluid on the aircraft are traduced by the global aerodynamic coefficients, the dimensionless forces and moments applied by the fluid on the aircraft. These coefficients depend on a high number of variables in a non-linear fashion. Among these variables are the geometry of the aircraft, its velocity and its rotation rates compared to earth, and characteristics of the surrounding flow. A representation model having a selected structure is determined for every aerodynamic coefficient, in order to represent these complex dependences. This model rely on experimental data obtained on a scale model, free flight data on a real aircraft being too expensive and too risky to get in the post-stall domain. Another way of obtaining data would be to use computational simulations. Nevertheless, the complex and unsteady flows around the 3D geometry of the aircraft makes the simulation too expensive with the current ressources, even if some recent studies begin to explore this direction of research. The selected models in the thesis are built on experimental data only. In the dynamic system, the global aerodynamic coefficients are evaluated by interpolation in these databases according to the selected model structure. The fact of selecting a simplified structure of the model makes it deficient. Moreover, as these models rely on experimental data, they are uncertain. The gaps and the uncertainties of the model have some impacts on the flight predictions. The initial objective of the thesis is therefore to study these impacts.During the thesis, new scientific objectives appeared, objectives going beyond the scope of Flight Dynamics. First, a new multi-element surrogate model for Uncertainty Quantification based on modern Machine learning methods is developed. Multi-element surrogate models were developed to address the loss of accuracy of Polynomial Chaos model in presence of discontinuities. Then, a formula linking the sensitivity Sobol indices to the coefficient of a multi-element surrogate model is derived. These results are used in the case of Flight Dynamics in order to address the issue raised in the initial objective of the thesis. The numerous bifurcations of the dynamic system can be traduced by discontinuities and/or irregularities in the evolution of the state variables compared to the uncertain parameters. The methods of Sensitivity Analysis and of Uncertainty Quantification developed in the thesis are therefore good candidates to analyse the system
