What is it about?

There are many uncertainties in numerical aerodynamics: in the angle of attack, Mach number, geometry. We implement and compare 5 different methods to quantify uncertainties. We show that gradient based methods perform better. We compute the mean value, variance and exceedance probabilities of the lift and drag.

Why is it important?

Results could be directly used by Airbus, DLR, NASA, Boeing .


Having effective and trustable methods to estimate uncertainties, one can reduce the risk and then the finance cost.
