Abstract
Bird strike is one of the major threats in the aerospace industry as it can result in serious structural damages and fatal incidents. The current study addressed the bird strike to the airplane windshield both experimentally and numerically. The windshield was considered to comprise glass and polycarbonate (PC) layers as well as TPU interlayer. The bird mass and speed upon collision to the windshield were considered 80–180 m/s and 1.8 kg, respectively. The experimental findings and numerical simulation results showed a proper agreement. The results also revealed the higher strength of the windshield with polycarbonate layer compare to the one with glass main layer. Bird strike with W-1 at the velocity of 160 m/s showed no fracture while the windshield with pure glass main layer broke upon bird strike at velocities below 120 m/s. The influence of various layouts was also assessed. Finally, it can be concluded that the incorporation of polycarbonate enhanced the strength of the windshield.
期刊介绍:
The International Journal of Impact Engineering, established in 1983 publishes original research findings related to the response of structures, components and materials subjected to impact, blast and high-rate loading. Areas relevant to the journal encompass the following general topics and those associated with them:
-Behaviour and failure of structures and materials under impact and blast loading
-Systems for protection and absorption of impact and blast loading
-Terminal ballistics
-Dynamic behaviour and failure of materials including plasticity and fracture
-Stress waves
-Structural crashworthiness
-High-rate mechanical and forming processes
-Impact, blast and high-rate loading/measurement techniques and their applications
