Abstract
Avari is a Homeland Defense Interceptor designed to meet the 2005-2006 AIAA Undergraduate Team Aircraft Design Competition RFP. Avari uses the maximum amount of existing technologies possible to minimize the overall cost. As the cost is repeatedly highlighted by the RFP, this became a major design driver. To meet this cost, the selections of low-cost and easily manufactured materials was a high priority along with minimizing the overall aircraft weight, as most aircraft are ?bought by the pound.? The large loiter section of the Combat-Air Patrol mission created a large fuel requirement, which created a large empty weight. Notable requirements that are met include takeoff and landing distances less than 8,000 feet, a loiter time greater than 4 hours, a dash speed greater than 2.2, and a flyaway cost of under $15 million. Materials, maintenance, manufacturing, and cost are kept minimal by using existing technology and low part counts.
