Cooperation with Tecnam aircraft industry to perform wind-tunnel tests on the new 11-seat commuter aircraft P2012 Traveller are still in progress. The aircraft has been designed by Prof. Luigi Pascale, designer of several light aircrafts. Support in the aerodynamic design and loads has been carried out. Winglet design, and wing loads have been estimated with attention to winglet, nacelles and fuselage effects. Wind-tunnel tests are focused on both longitudinal and lateral directional characteristics. Mutual aerodynamic components effects are under investigation.
