Low-cost fixed-wing construction techniques for UAS curriculum

Abstract

Unmanned aircraft systems (UAS) offer an exciting platform to teach students about basic principles of aerospace engineering and the systems engineering design process, and to utilize these for investigation of important scientific phenomena. The widespread popularity of UAS, the emergence of affordable and capable systems, and recent advances in policy by the Federal Aviation Administration (FAA) have created a permissive climate where these may be effectively used by students as a means by which to conduct scientific research or may serve as the focus of a systems engineering design project in their own right. UAS-based projects and hands-on courses provide stimulating and relevant learning opportunities many students are seeking today. While rapid prototyping is commonly used in making components for widely popular rotary-wing UAS (generally in the form of 3D printed components), similar technology may be brought to bear on the design and fabrication of somewhat more complex fixed-wing aircraft. In addition to 3D printing, the efficient design of fixed-wing UAS often requires the use of composite materials, larger sizes, complex geometries, and novel fabrication techniques. Additional challenges include the need for precise control of weight and balance, control surfaces, and desired flying qualities throughout the range of flight regimes for fixed-wing UAS. This paper describes efforts being employed within University of Alaska Fairbanks (UAF) courses, student research activities and clubs to further the design and construction techniques used in fixedwing UAS assets, and how these assets will support UAF's research portfolio. It also briefly outlines existing efforts and potential future activities to offer UAS-related STEM opportunities to local high school and middle school students.
