According to the basic theory of wind turbine blade, a SG6050 airfoil wind turbine blade model was built with a radius of one meter. Based on the bionic principle, the fiber angles varied from 5° to 90°. In order to reflect the symmetry of medial axis, negative angles were included corresponding to positive angles. The comparison between different plies was made through reliability theory based on the response surface method. The result shown that the fiber angles between 40° and 70° had higher reliability and 65° has the highest reliability.

... At the same year, Ma et al. [101] analyzed the structural similarity between Dragonfly membrane fin and aircraft fuselage reinforcement frame, extracted the structural characteristics that determine the excellent mechanical properties of dragonfly membrane fin structure(polygon unit and wing angle), and applied them to the design of aircraft fuselage reinforcement frame. Liu et al. [102,103] designed wind turbine blades based on the characteristics of plant leaf vein distribution and mechanical properties. According to the high similarity between human respiratory system and engine intake-and-exhaust system, the model of automobile exhaust manifold was established [104][105][106][107] by using human bronchus, and verified the mechanical performance analysis respectively. ...
