Width Example

Below are examples showing how to calculate the four parts of the wing. There are calculations for both the 2 and 10 meter turbines. This is the calculation for the 2 meter turbine (3,14 m2)

1. First part; the Momentum points are 1/4 out on the cord measured from the profile end.

The blade width 75% out on the wing is = 0,15 m

2. Second part; The blade width 50% out on the wing is = 0,18 m

3. Third part; The bladewidth 25% out on the wing is = 0,29 m

4. Fourth part; The blade width 25% out on the wing is = 0,54 m

Below: Ca = Lift force coefficient chart

These are the calculations for the 10 meter turbine (78,5 m2):

1. First part; the Momentum points are 1/4 out on the cord measured from the profile end.

The blade width 75% out on the wing is = 0,35 m

2. Second part; The blade width 50% out on the wing is = 0,44 m

3. Third part; The bladewidth 25% out on the wing is = 0,73 m

4. Fourth part; The blade width 0% out on the wing is = 1,35 m
