Abstract

The rule of damage on the vortex vane in the particle separator caused by bird impact was studied with a view to improve the resistance design of particle separator to foreign object damage.By the method of experiment on impact damage

the process in which the vortex vane in the particle separator is impacted by a model bird was researched.By using the system of measurement and test on transient response

the strain-time history of the vortex vane impacted by model bird was gained.Profile of the vortex vane before and after the impact inflicted by the model bird was obtained with a three-coordinate device.Through comparison and calculation the deformation of the vortex vane after the model bird impact was gained.It is found that plastic strain in the vortex vane emerges and the deformation of the vortex vane is very large when the model bird impacts the vortex vane at the velocity Ma=0.2.
