Problems solved by technology
Mobility and ease of use are somewhat limited for existing UAS.
Further, the assembly of some existing UAS aircraft may be accomplished with tools that may be difficult to operate in limited visibility conditions or by soldiers wearing protective gear such as gas masks or gloves.
The limited mobility and difficulty of assembly in certain conditions may hamper the effectiveness of UAS by front-line soldiers in combat situations.
The bulky crates may hamper the mobility of the soldiers and limit the front-line scenarios in which an UAS may be used.
If the assembly of the UAS in the field requires an inordinate amount of time to unpack, assemble, and / or deploy, the resulting delay in obtaining critical intelligence may squander a window of opportunity to complete a mission or potentially endanger the lives of personnel.

Fabrication of Prototype Collapsible Wing
[0099]To demonstrate the feasibility of fabricating a collapsible wing with extendable wing sections, the following experiments were conducted. The collapsible wing fabricated in this experiment was composed of four hollow wing sections that nested inside each other in the collapsed configuration, where each wing section had a span length of about 9″. In the extended position, each wing section inboard of the root section had an exposed span of about 7.5″ and an overlap of approximately 1.5″ between the adjacent wing sections.
[0100]The wing sections were fabricated from a carbon fiber epoxy composite material using a carbon fiber wet layup method. In this method, the sheets of carbon fiber were soaked with epoxy, and the epoxy-soaked sheets were then squeegeed to remove excess epoxy to form epoxy-impregnated carbon fiber sheets. The impregnated sheets were then wrapped around a mold in the shape of the wing span section. In order maintain tig...

Description
CROSS REFERENCE TO RELATED APPLICATION[0001]This application is a divisional of prior U.S. application Ser. No. 13 / 463,516, filed May 5, 2012, which is hereby incorporated by reference herein in its entirety. Prior U.S. application Ser. No. 13 / 463,516 claims the benefit of U.S. Provisional Application No. 61 / 482,079, filed on May 3, 2011, which is hereby incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]This application relates to a collapsible wing, methods of producing the collapsible wing, and an unmanned aircraft system that includes a collapsible wing.BACKGROUND OF THE INVENTION[0003]In modern-day military operations, unmanned aircraft systems (UAS) may be carried by front-line soldiers for use as a quick source of intelligence as needed. In those areas of interest which are too dangerous for humans to investigate first-hand, a UAS may be assembled and launched to observe the area of conflict using an array of intelligence, surveillance, and reconnais...
