Executive Summary 1 iSpy is a twin fuselage EP-UAV powered by two electric motors and two 4-cell batteries with aerial photography and video capturing capabilities from a range of altitudes. The design requirements set out by the course outline was set as the minimum performance requirement for this project. The initial design ideas that were discussed involved various configurations, which ranged from complicated, challenging concepts to extreme simplicity which involved considering nothing outside the course requirement for this project. Some of these sketches are shown below in figures 1.01 to 1.06 Figure 1.01 Figure 1.02 Some of these designs were scratched at initial discussions itself due to their lack of ingenuity or design brilliance. Sketches shown in figures 1.04 and 1.05 are examples of these. Others were left out due to the lack of time, money and man hours required to complete this project, such as the design shown in figure 1.06. The final design that was chosen, however, was the idea based on creating the Virgin Galactic’s Global Flyer replica. The idea blossomed with discussion and soon the basic sketches grew into many drawings with minor details and the final decision was made. A twin fuselage design with a high aspect ratio wing and an H-tail that can carry a pod in the middle that can be modified to be used as spy plane with an onboard camera was the team’s favourite. The payload may also be this pod with additional space within to hold metal blocks or sand bags. Figure 1.03 Figure 1.04
