25 UAV Design Problem How does the wing design of a UAV impact the success or failure of a military scenario? 1. How does the wing geometry impact UAV performance? 2. How does performance impact probability of detection? 3. How does detection impact the mission likelihood of success? 4. What is the cost impact?

26 Strategy 1. Use domain specific tools for calculations OpenVSP: Aircraft Geometry ACSYNT: Aircraft Performance STK: Mission Analysis Excel: Cost 2. Automate each tool and the hand offs between them 3. Run automated studies to generate point clouds of data for analysis
