Two, area of section=the first of 1-3 times of size difference=maximum blade thickness of third reinforcing rib, the second reinforcing rib adds
The 50%-70% area of section of strengthening tendons, 25%~50% area of section of third reinforcing rib=first reinforcing rib.
Third reinforcing rib is connected between two neighboring second reinforcing rib in first reinforcing rib side, so that two neighboring second adds
Strengthening tendons and third reinforcing rib form the circuit of closure.
Third reinforcing rib is punished out from the 1/2 of the second reinforcing rib of the first reinforcing rib side and third adds in this direction
Strengthening tendons are connected at the 1/3 of adjacent second reinforcing rib.
The suction surface of blade is arranged in third reinforcing rib, and third reinforcing rib center line is in arc-shaped or multi-section-line combination respectively
Spline curve, the third reinforcing rib camber direction on blade is consistent with the blade surface grain direction respectively, to subtract
The aerodynamic drag of small reinforcing rib.
First, second, and third reinforcing rib of the invention increases blade strength and rigidity, reduces aerofoil fan work operating
When deformable blade, and reduce blade disintegration risk.
The small boss structure of first, second, third reinforcing rib and blade surface can generate flow-disturbing in turn when blade rotates
Blade surface boundary layer is destroyed, reduces resistance of the blade by air, to reduce fan power consumption.
Reinforcing rib structure of the invention is the reinforcing rib based on vein biomimetic features, and reinforcing rib is according to bionics principle
Design has better blade strength and fluid property compared with common reinforcing rib.
