Blade:Streamlined variable cross-section 1.0.059''thickness No.5052 aviation aluminum alloy plate,not break when impact 2.To aerodynamic equal chord length theory,the blade narrows and thins from root to tip till tail then widen,more uniform 3.17Ibs per blade(24ft),5 blades total 84.9Ibs.more safe |
|
Wheel Hub(chassis):
7075 aviation aluminum plate after CNC precision machining,perfect appearance and metal streamline to ensure the mechanical performance.After machining, max tolerance is 100μm, to ensure the dynamic balance.
|
Blade shape- Streamlined variable cross-section | Blade shape- transverse section,equal width section |
The blade section is from wide to narrow (304-186mm),from thick to thin (43mm-21mm).Adopts the equal chord length principle and relative linear velocity characteristics to ensure the balance pressure of the whole blade to achieve the tip,middle and roots air evenly including the middle. |
The blade length is equal with cross section ,blade width is 19CM.High air resistance is not conducive to pushing airflow, holes in the middle, high energy consumption. |
|
|
Blade material- aviation aluminum sheet | Blade material-Low grade aluminum |
Adopt NO.5052H32 1.5mm thickness aviation high grade density aluminum alloy original plate,with high strength and flexibility,bright and durable. |
Low grade aluminum mixed with recycled aluminum for secondary processing, low density, impurities, pores, low toughness and easy to break |
Blade weight-light | Blade weight-heavy |
Each blade 6.7KG,total weight for 5pcs 33.5KG.Smaller blades ,lighter weight, reducing the motor load and extend service life, low energy consumption. | Cross section width equal to the blades, Each blade 10KG,normal 6pcs or 8pcs.Heavy weight, large motor load, high energy consumption. |
