Project Review Micro Air Vehicle Project: P07121 02.23.07 Sponsored by Impact Technologies The Boeing Company Mark Baybutt Electrical Engineering David Blonski Industrial Engineering Team Leader Andrea Wyant Electrical Engineering Geoff Amey Computer Engineering Perry Young Mechanical Engineering Daniel Segar Mechanical Engineering Patrick O’Neil Mechanical Engineering Timothy Nowicki Mechanical Engineering Benjamin Metz Mechanical Engineering Jeffrey Kozak Customer / Guide Mechanical Engineering

2. 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

3. 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

4. P0121: Old Design

5. P0121: Concept Selection

6. 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

7. 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

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

9. 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
