Abstract	This summary report described the design of two aircraft. The first aircraft is a full-scale UAV intended to perform scientific missions in Polar Regions. The second aircraft is a half-scale stability and control demonstrator intended to prove the feasibility of the full-scale Polar UAV.0 The Polar UAV was developed and designed for a CReSIS research program. CReSIS (Center for Remote Sensing of Ice Sheets) is a national research program that intends to study the mass balance of polar ice sheets and its potential impact on global sea levels. CReSIS requested proposals for an air vehicle to perform the mission of observing the thickness and motion of the ice sheets. This mission necessitates long flights and substantial risk. These factors suggest that unmanned aircraft will be a good alternative to a human-piloted aircraft. Therefore, the aim of this project is to develop an UAV that will meet the mission requirements both in the Antarctic and Greenland. Before the start of this project, The University of Kansas aerospace engineering students developed a conceptual design of a polar UAV in 2002. This design concept has been substantially modified using updated requirements then defined to a higher level of detail. This design project delivers a complete preliminary design of the full-scale Polar UAV and a complete detailed design of a half-scale demonstrator. The design of the UAV concept for use by the CReSIS center has evolved significantly from its rough state at the beginning of this project. The Cryohawk design meets a well-defined mission statement and operational profile. The design was taken through a class 1 and class 2 weight sizing, a new performance matching, and a full set of aerodynamic calculations. Then a stability and control analysis was completed. The design meets the CReSIS center’s needs. On top of the accomplishments made toward furthering the design of the full size UAV, a 50% scale flight test demonstrator was successfully designed. A design and AAA analysis was done on this scaled aircraft. This aircraft is being manufactured and will be completed before the end of the Spring 2006 school semester. This vehicle will serve as a useful tool in future academic endeavors. Lastly, successful cooperative relationships have been established. This project successfully expanded the envelope for graduate design/build/fly class projects. There is now an established avenue for interaction with the AE 510 undergraduate manufacturing class and with the Engineering Technology Program at Pittsburg State. There are other relationships that need to be built further, such as those with Kansas State University and Embry-Riddle, as well as other classes and departments at The University of Kansas. All of these accomplishments have been combined into a successful and growing program.
