Oar disk center is 90mm to the distance of blade 1 end.
As a example by oar dish diameter 180mm, blade 1 at the center of the oar dish formed with propeller is apart
At 50mm, the angle of attack of (i.e. the 55.6% of 90mm) is 15.1 °, and chord length is 16.5mm;Blade 1 exists
With the center of the oar dish of propeller formation for the angle of attack of (i.e. the 72.2% of 90mm) at 65mm it is apart
12.7 °, chord length is 14mm;Blade 1 at the center of the oar dish formed with propeller at for 80mm
The angle of attack of (i.e. the 88.9% of 90mm) is 11.2 °, and chord length is 11.5mm.
Further, with oar disk center distance 35mm (i.e. the 38.9% of 90mm) place, blade 1
The angle of attack be 19.4 °, chord length is 18.9mm.With oar disk center distance 90mm (i.e. the 100% of 90mm)
Place, the angle of attack of blade 1 is 10.5 °, and chord length is 10.1mm.
It is understood that because of Section A-A, section B-B, C-C cross section, D-D cross section and E-E
The position in cross section can slightly change, therefore correspondingly, Section A-A, section B-B, C-C cross section,
The angle of attack chord long value of D-D cross section and E-E section gained can change accordingly.
The chord length in above-mentioned each cross section and the setting of the angle of attack all can be set with the size of oar dish.This enforcement
In example, blade 1 can be provided with connecting hole 2, distance L6 of connecting hole 2 to oar disk center can be
14.5mm.Blade 1 can realize the connection with oar seat, simple in construction by connecting hole 2, it is simple to operation.
It addition, the propeller provided according to the present embodiment, the pitch of blade 1 can be 29mm, it may be assumed that
Blade 1 rotates a circle, and the theoretical distance risen is 29mm.
The above-mentioned propeller that the present embodiment is provided, surveys by carrying out contrast with propeller of the prior art
Examination, understands with reference to table one, and under identical pulling force, the power of the propeller that the present embodiment is provided is more
Low, namely: under less power condition, there is bigger pulling force, thus reduce kwh loss, increase
Add endurance distance.
The propeller that table one the present embodiment is provided and the reduced parameter of prior art
