Once the best durable hydrophobic coatings for insect mitigation are selected, 

two types of validation tests will be performed :  

TESTS IN WIND TUNNELS

TESTS WITH DRONES


TESTS IN WIND TUNNELS


The COLD WIND TUNNEL facility (CWT-1) at the von Karman Institute for Fluid Dynamics can achieve maximum flow from velocities of 65m/s within seconds. Running in a close-loop configuration, it can work at flow temperatures as low as -30°C. Additionnally, large double-glazing walls at the test section provide optical access for flow visualization.

TESTS WITH DRONES


The technology developed in the CHOPIN project will soon be tested in a realistic environment by using drones flying through swarms of insects. The scientists can validate the performance of the coatings by comparing insect adhesion between a coated and non-coated part of the samples.
