Aerodynamic device for reduction of vibrations generated from rear trap doors of front landing gear of transport aircraft, has set of individual aerodynamic elements formed to form swirl structures with controlled intensity and frequency

摘要

The device has a set of individual aerodynamic elements (5) arranged upstream of rear trap doors (3, 4) in a side-by-side manner so as to cover full width of the trap doors. The set of individual aerodynamic elements is formed to form swirl structures with controlled intensity and frequency. Each aerodynamic element corresponds to a wing (7) that is positioned to form an angle ranging between 5 degrees and 25 degrees with respect to a local flow, where the wing is made of metal. Pressure difference between an upper face and a lower surface forms the swirl structures.
