2. Overview Problem Statement Product Specifications Final Design Project Status Parts Received Potential Issues Testing Gantt Chart 1

3. Problem Statement Design and develop a Bomb Rack Unit (BRU) that is attached to the Tigershark UAV capable of housing and launching a cylindrical payload. BRU must contain an electrical box which will allow space for an electrical team to design and integrate an electrical interface to control in-flight operation of the BRU. Provide budget analysis for BRU Design and construction of a prototype 2

4. Tigershark UAV Platform Specifications: Wing span 21 feet Propulsion - 372cc two stroke 20 gallon fuel tank Empty airframe weight - 150 lbs. Gross take off weight - 300 lbs. Payload capacity – 50 lbs. One hard-point location per wing for launcher attachment 3

5. Constraints BRU must not exceed 5 lbs. Capable of holding a payload that is 10lbs Operation in temperature range -20 to 60 degrees C and during rain exposure Retain payload during aircraft maneuvers up to 2GS lateral load and 1G landing shock. 4
