In science:

Our goal is to generate surrogate models for scalar aerodynamic coefficients lift (cl ), drag (cd ) and pitching moment (cm ) for two-dimensional airfoil geometries, which depend on the input parameters Mach number (Ma) and angle of attack (α).
Efficient response surface methods based on generic surrogate models
For two-dimensional airfoil geometries, we approximate the aerodynamic coefficients lift (cl ), drag (cd ) and pitching moment (cm ), depending on the Mach number and the angle of attack α.
Efficient response surface methods based on generic surrogate models
For each airfoil, we compute an accurate surrogate model for each problem class (cl (Ma, α), cd (Ma, α), cm (Ma, α)) in the reference domain Ω := [0.2, 0.9] × [−4◦ , +12◦ ].

Jansen has used generalized top-hat filtering in his dynamic LES of airfoil flow because this method has been found to be cheaper than the Taylor series method and yet gives similar accuracy (Jansen, 1999), in the context of his specific code.

It is surrounded by low aspect ratio rotating cylinders in contact with the ground, and it is equipped with leading and trailing edge airfoils, the leading edge device also being in close proximity to the ground.
Explanation and discovery in aerodynamics
Since the next competition is only one year away (no time to invent the airfoil), the optimal strategy is universally observed by potential contestants to involve building a bigger pair of springs.
Lessons from a Restricted Turing Test
In short, this is because such limited tests are better addressed in the near term by engineering (building bigger springs) than science (discovering the airfoil).

The flight of a fixed-wing airplane could, at least in principle, be described by nearsteady, zero-viscosity, irrotational theory of airfoils, which was already available at the beginning of the twentieth century.

Classical airfoil theory explained satisfactorily the balance of forces in a wing in steady flight.
Boundary layers and the vanishing viscosity limit for incompressible 2D flow
The theory predicts that the lift and the drag are proportional to the circulation of air velocity around the airfoil, and it was in agreement with experiments, see for details.
