Mission –Complete surveillance portion of the 2007 International Micro Air Vehicle Competition by improving, but not redesigning, last year’s MAV. Background –Fourth MAV senior design team –Third year competing in MAV Competition –Never has a team completed the competition Requirements –Fly 1200m –Take two “legible” pictures –Wireless remote control P0121: Project Description –Onboard power supply –Deliver hardcopy of photos –Stable launch

P0121: Needs and Specs Customer Needs Rebuild last year’s MAV Improve flight capabilities Increase lift Improve pod aerodynamics Increase stability Improve power efficiency Increase thrust Improve power efficiency Decrease weight Decrease max linear dimension Increase camera capabilities

P0121: Old Design

P0121: Concept Selection

P0121: New Design Feigao Motor 3”x2” Prop Smaller Tail Tear-drop Pod 10 o Angle of Attack Berg 4L Receiver 2S 730mAh Battery Reoptimized Airfoil Twill-Weave Carbon Composites

P0121: Design Summary Propulsion System (motor, prop, batteries) –Reduced counter-torque –Increased range Berg 4L receiver –Decreased weight Teardrop pod –Reduced drag –Increased velocity –Fixed center of gravity Re-optimized airfoil –Increased lift Smaller Tail –Decreased weight –Increased mobility Angle of Attack –Increased lift Twill Weave Carbon-Composites –Same physical properties as twill weave –Increased availability

P0121: Product Development Process Phase Current Phase of Development MSD IMSD II

P0121: Current State of Design Summary –Design meets all major customer needs –Design expected to meet all engineering specifications except: Weight < 96g Max Linear Dimension < 7.5in –On target to stay within budget: Budget = $4000 Less than $1000 spent in SD1 –On schedule Risk –Weight –Manufacturability of Pod –Range of receiver Mitigation –Step-by-step concept implementation –Standardized testing procedure
