ODU UAV TEAM 2013
John Plank, Ethan Pratt, Michael Midkiff
Kenneth Jermstad and Ignacio Santos
Proudly Present:
Advisor: Dr. Drew Landman
Project Overview:The UAV project was formed because of the lack of senior projects that dealt exclusively with Aeronautics engineering
Goals of the Project:To design, build and fly a UAV that could be assembled from a suitcase
•Calculate in-flight parameters to analyze performance.•Lift coefficient. Induced drag coefficient.•X, Y, Z coordinates of leading edge, chord length, airfoil.•Mass and inertia breakdown.
AVL and Tornado programs

First Test Flights:On April 13 several attempts to get the Bixler to fly autonomously end unsuccessfully when the Bixler suddenly darts out of control and crashes
Success:On April 20 a major project goal is accomplished as the Bixler achieves autonomous flight

Pod Design
• Revolved NACA 0018 Airfoil • Chord: 500mm
Machining the Pod
• Cut on Lathe with increments every 1/16”
Machining the Pod
Pod Cavities
• Cavities for electrical components– Carved using wood tools– Carved using Dremel
Pod CavitiesLaser Cut Motor Mount
Hand Tapped Holes Boom Mount
Cavities for Electrical Components
Tail Design
12” Span Tail 15” Span Tail 19” Span Tail
Stable Boom Length
4” up to 23”
4” up to 15” 1” up to 9”
•Stability estimated using tail volume coefficient (Ch)
•Stable range: 0.3 < Ch < 0.6
•Decided to reduce span to 15”
