Bird Impact Analysis on Windshield of N-245 Aircraft Using Ansys Program
Analysis of bird impact on the windshield is a necessity in the aircraft design process. N-245 is the development of PTDI new products departing from CN235 aircraft which was the object of this research. The analyzed N-245 windshield has dimensions of 757 m x 524 mm x 20 mm with polyvinyl-butyral (PVB) material. Bird geometry is assumed to be a cylinder with a dimension of 200 mm in length and a diameter of 100 mm. In this research, the finite element method – Ansys computer program is used for impact analysis to calculate deformation, stress, and strain. Three analysis variables were applied in this study, namely speed, location of impact and angle of arrival of the bird model. The results showed the greatest deformation, stress, and strain impacts occurred at a speed of 200 m/s which is located in the middle of the windshield at an angle of 15 degrees.
