Abstract
By reducing the loading on the outer portion of a wing, the bending moment can be reduced with little increase in drag, allowing for a lighter wing structure compared to a conventional wing.
Description
KUDOWA WING.
Wing Lift Distribution.
On conventional wings the lift distribution is approximately elliptical across th span.
This gives the lowest induced drag for a given span, but not the lowest bending moment (structural weight) for a given level of drag If the outer wing loading is significantly reduced the bending moment is reduced with little change in drag. This improves the drag/bending moment ratio The outer low loaded section is about 25% of the span, but may be greater or less depending upon the particular application.
Figure 1 A. Shows the lift approximate lift distribution of the Kudowa wing.
B. Shows the approximate lift distribution of a standard wing.
(the area under the curves are equal).
The significant factor is that the lift on the outer wing is significantly reduced compared with the conventional wing.
Claims (4)
- CLAIMS An off loaded outer wing reduces the bending moment allowing greater span and reduced drag.
- 2 The drag is reduced compared to a normal wing of similar bending moment.
- 3 The bending moment is reduced compared to a normal wing of similar span.
- 4 To be effective there is a significant difference in the lift between the inner and outer sections of the wing.
