[Retracted] Research on Optimizing Selection and Optimizing Matching Technologies of Aeroengine Fan Rotor Blades

Table 4

Ten groups of rotating blades picked out by the algorithm based on the collocation degree of blades.

	First-order bending dispersion	First-order torque dispersion	Gravitational moment difference (gmm)
Design requirements (blade selection rules)	0.06	0.08	6000
The blade group of the first rotor	0.054	0.056	5900
The blade group of the second rotor	0.054	0.040	6000
The blade group of the third rotor	0.055	0.047	5780
The blade group of the fourth rotor	0.055	0.059	5640
The blade group of the fifth rotor	0.054	0.078	5400
The blade group of the sixth rotor	0.054	0.059	5980
The blade group of the seventh rotor	0.054	0.059	5820
The blade group of the eighth rotor	0.056	0.074	5940
The blade group of the ninth rotor	0.053	0.064	5980
The blade group of the tenth rotor	0.054	0.079	5800
