To date, the impact phenomena of insects on surfaces are not fully addressed. Indeed, impact onto airfoils and flat aluminum substrates at different impact angles (10° to 90°) and velocities (20-100 m/s) were investigated. Furthermore, a complete comprehension of the impact mechanism is lacking.
Impact experiments with Drosophila Hydei onto aluminum and glass, flat and curved substrates, were conducted on a rotating structure setup.
We present our findings regarding the residue area and pattern as a function of impact angles and velocities. Detailed residue formation from impact to dried spatter will be presented as well.
