Abstract:

Bird strikes are one of the biggest threats to flight safety in aviation. Bird strikes occur in every 2000 flights. 90% of foreign body damage in aviation is caused by bird strikes. In the event of a bird strike, the most critical parts of the aircraft are the nose, windshield, engine, inlet, wing front edges. Bird strikes usu-ally occur during the landing and take-off moments of the aircraft. In addition, factors such as the increase in the number of flights in the globalizing world and the migration status of birds play a role in the increase of these cases. In 15% of bird strikes, the aircraft is seriously damaged. Aircraft components must have a certain durability to minimize damage for flight safety. Criteria for critical parts are set in aviation regulations. To meet these criteria, aircraft components must successfully complete bird strike certification tests prior to flight. Due to the cost of physical tests, analyzes based on numerical simulations are carried out in par-allel with certification tests. The purpose of this analysis is to predict the damage to the aircraft by the verified bird model, to make changes to the aircraft compo-nent design and material when necessary, and to reduce the cost. In this review, the theoretical background of the bird strike problem, finite element analysis (model bird materials, bird modeling methods, bird geometry) and tests in the relevant literature will be discussed.
