Abstract

A wing for use in a flapping wing aircraft, having a strut assembly including a main strut and a plurality of support struts each oriented at an angular interval between 30 degrees and 90 degrees with respect to the support strut, at least a section of the support struts having a front section, a connecting section adjacent thereto, and a rear section adjacent thereto, and wherein each of said support struts is secured to said main strut by said connecting section, and further having a group of planking members made of a resilient and dimensionally stable sheet material and connected to said strut assembly.

First claim

What is claimed is:

1. A wing for use in a flapping wing aircraft, comprising a strut assembly including a main strut and a plurality of support struts each oriented within an angular interval between 30 degrees and 90 degrees with respect to the main strut, wherein at least one support strut has a front section, a connecting section adjacent thereto, and a rear section adjacent thereto and wherein the connecting section is fixed to the main strut, and further comprising a group of planking members which are made of an elastic and dimensionally stable foil material and which are connected to the strut assembly, and
wherein the connecting sections are connected in a rotationally fixed manner to the main strut.

2. The wing according to claim 1 , wherein the main strut is extended along a straight line and/or wherein at least one of the supporting struts is extended along a straight line.

3. The wing according to claim 1 , wherein an end region of the front section spaced apart from the connecting section is connected to an arcuately formed edge strut which extends between the end regions of maximally spaced-apart support struts of the strut arrangement.

4. The wing according to claim 1 , wherein a length of the rear section of the support strut is at least 2 times of a maximum distance between the main strut and the edge strut.

5. The wing according to claim 1 , wherein adjacently arranged support struts delimit an angle between 0 degrees and 25 degrees with one another.

6. The wing according to claim 1 , wherein a front surface area which, starting from the main strut, spans the front sections of the supporting struts is provided with a front planking member belonging to the group of planking members, which is fixed to the main strut and to the front sections.

7. The wing according to claim 1 , wherein a rear planking member extends from the main strut along the rear section of one of the supporting struts, which rear planking member is fixed with an attachment region to the rear section of the supporting strut, wherein a free end region of the rear planking member covers a rear section of an adjacent support strut or covers a projection of another rear planking member which is fixed to a rear section of an adjacent support strut.
