Blades- Airflow components

1.Blade design-Streamline variable cross-sectionConform to aerodynamic equal chord length theory,combined with the relative linear velocity principle,the blade narrows（304-186mm) and thins(43mm-21mm) from root to tip till tail then widen,the air is more even and uniform.

2.Blade material-Aviation aluminum alloy1.5mm thickness No.5052H32 aviation aluminum alloy original plate,precision CNC molding,high strength and flexibility ensure the blade not to be broken.

3.Blade weight-More lighter and safer6.7kg per blade(24ft),less blades,lighter weight,it can reduces the motor load,prolong the life,more safe and cost-efficient.

Connection:patented full mortise and tenon structural design to ensure the whole fan safety:

1.Blade and petiole

Mortise and tenon connection:The convex petiole with concave buffer device form the Joint engaged,eliminate the centrifugal force from the blades when the fan is running and the shear force when the fan starts and stops.The transverse screw is the same direction with fan running track to avoiding the shear in order to ensure the blade will not broken,eliminate the possible Safety hazards radically.

2.Petiole and wheel hub

The petiole and hub/motor are integrated by the stepped concave-convex sections to engage each other.The overall structure is used to withstand the centrifugal force during running,and all fasteners are not stressed.

3.Motor and flange roulette

Safety ring:Connect the 5 petioles and motor upper cover form the whole,adopt the occlusion structural to even the force of the whole fan.Anti-falling roulette:The concave flange roulette engaged with the convex anti-falling ring each other under the gravity to ensure the reliable connection between the flange roulette and motor.
