Abstract

These tests and examples show the detrimental losses in performance caused by the contamination of insects. The airfoils designed for high performance turn out to be the most vulnerable ones. Perhaps some relaxation of performance of the clean airfoil, thereby resulting in a smaller loss to insects, would be a compromise. F. X. Wortmann showed in 1963 that contamination by insects can be avoided by the use of an elastic airfoil nose. The high expense of an airplane with high performance makes it desireable to look for a way to guarantee this performance to a certain degree, even with roughness due to insects.
