Aircraft component with structural foam
An aircraft component including a structural foam having a predetermined shape, an outer flange located near a first end of the structural foam, an inner flange located near a second end of the structural foam, a web skin encapsulating the inner flange and at least a portion of the structural foam wherein the structural foam is affixed to the web skin, wherein the aircraft component comprises a portion of a blended wing body aircraft (BWB), the BWB having no demarcation between a wing and a main body of the BWB.
1. An aircraft component comprising:
a structural foam having a predetermined shape;
an outer flange located near a first end of the structural foam;
an inner flange located near a second end of the structural foam;
a web skin encapsulating the inner flange and at least a portion of the structural foam, wherein the structural foam is affixed to the web skin, and wherein the aircraft component comprises a portion of a blended wing body aircraft (BWB), the BWB having no demarcation between a wing and a main body of the BWB.
2. The aircraft component of claim 1 , wherein the predetermined shape of the structural foam comprises a trapezoidal shape about a cross section.
3. The aircraft component of claim 1 , wherein the web skin comprises a carbon fiber material.
4. The aircraft component of claim 3 , wherein the structural foam comprises a closed cell foam and wherein the closed cell foam is impermeable to a resin of the carbon fiber material.
5. The aircraft component of claim 1 , further comprising:
at least one receiving portion, wherein the at least receiving portion is located at a first end of the aircraft component and extends in a direction towards a second end of the aircraft component, and the at least one receiving portion configured to receive a stringer component.
6. The aircraft component of claim 5 , wherein the at least one receiving portion is configured to receive a stringer component that is orthogonal to the outer flange.
7. The aircraft component of claim 5 , wherein the stringer component comprises:
a foam core;
and a stringer skin wrapped around the foam core.
8. The aircraft component of claim 1 , wherein the aircraft component comprises a portion of the main body of the BWB.
9. The aircraft component of claim 1 , wherein the outer flange is connected to an outer mold line skin of the BWB.
10. The aircraft component of claim 1 , wherein an end of web skin comprises a partial hook shape.
11. A method of manufacture for an aircraft component, the method comprising:
receiving a component mold having a mold cavity;
inserting a web skin into the component mold, wherein the web skin blankets a surface of the mold cavity;
inserting an inner flange into the mold cavity and onto the web skin, wherein the inner flange is in contact with the web skin;
filling the mold cavity with a structural foam, wherein the structural foam is situated on top of the inner flange;
placing the outer flange within the component mold and on top of the structural foam, wherein the outer flange and the web skin encapsulate the inner flange and the structural foam.
12. The method of claim 11 , wherein the web skin comprises a carbon fiber material.
13. The method of claim 12 , further comprising
introducing a resin into the component mold; and
infusing the carbon fiber material with the resin.
14. The method of claim 11 , wherein the mold cavity comprises a trapezoidal shape about a cross section.
15. The method of claim 11 , wherein component mold comprises a closed mold.
16. The method of claim 11 , wherein the structural foam is configured to provide a shape for at least the web skin.
17. The method of claim 11 , wherein the mold cavity comprises one or more planar surfaces.
18. The method of claim 11 , wherein the web skin takes the shape of the surface of the mold cavity.
19. The method of claim 11 , wherein inner flange and the structural form takes the form of the mold cavity.
20. The method of claim 11 , wherein filling the component mold cavity with a structural foam comprises encapsulating the inner flange between the web skin and the structural foam.
