China > Research Article 2017 2 10 2017 03 26 The aim of this research is to provide a new structural design of wing leading edge which is more resistive to bird strike according to safety measures mentioned in Federal Aviation Regulations (FAR 25.571). Bird-strike against wing leading edge is simulated in PAM-CRASH while structure of wing leading edge is modeled in CATIA V5. Bird in shape of cylindrical with hemispherical ends having a weight of 1.8 Kg is impacted against wing leading edge at a velocity of 150 m/s. Five new models of leading edge are developed and simulated. Those are named as case 2 to case 6. A traditional design of wing leading edge named as case 1 is also simulated under same conditions for results comparison with new designs. Each case is simulated for two scenarios of bird strike. The first scenario is when bird exactly hits the leading edge. The second scenario is when bird hits a position 125 mm vertically upward from leading edge. Simulation results showed that traditional design is more prone damage in first scenario than second scenario. Case 2 to 4 proved good in both scenario but these cases are much safer in first scenario. Case 5 and 6 showed good resistance to bird strike in first scenario but received considerable damage in second scenario. By comparing results of all cases, it is found that case 2 to 4 are better design for wing leading edge than traditional one. Copyright@ International Science Community Association
