Abstract
The effectiveness of drag-reducing laminar flow technologies can be limited by insect contamination on aircraft leading edges. Test equipment was developed to study insect impact events. The adhesion of Drosophila Melanogaster to five low-surface-energy coatings was evaluated (insect residue height and area were determined) and compared to measured surface energies and surface roughness. The dominant factor influencing the rupture speed (i.e. the lowest speed needed to fracture the exoskeleton) was seen to be the orientation of the insect body relative to the surface on impact.
