    1. F3A Pattern World Championships Design Project Proposal AAE 490T/590T February 9, 2001 John Castro Loren Garrison Chris Peters Jeff Rodrian Thomas Schmidt-Lange

    2. Presentation Overview Mission Objective Baseline Design Aircraft Progression Design Strategies Construction Strategies Project Timeline Project Proposal

    3. Mission Objective Design & Construct an F3A Pattern Aircraft for use in the 2001 World Championships Replace Existing 1997 Design to adapt Pattern Evolution Tailor Aircraft to the Flying Abilities and Style of the Pilot, Jose Melville Shift Design from Typical Pattern Style to IMAC Style Project Proposal

    4. F3A Competition Constraints Pre-set pattern which changes yearly Size Constraint 2 meter maximum length 2 meter maximum wingspan Project Proposal

    5. Fixed Parameters Power Plant (YS 140 Limited) Exhaust Pipe Fuel Weight Avionics Accessories Project Proposal

    6. Baseline Model – ‘Wild Beat’ Designed for past pattern maneuver style Customer desires a plane with Better snap characteristics, Constant velocity during the entire pattern Better pitch authority Project Proposal

    7. Pattern Aircraft Evolution Increase in overall size of the aircraft Trends in Design Style Changes towards IMAC Designs Wider Fuselages Shorter distance between wing and horizontal tail HT/wing and control/lifting surface area ratio Project Proposal

    8. Concentrate on Design by Empirical Data Use Engineering Judgment for Modifications Primary Design Modifications Fuselage Size Width, height, and length Wing ¼ chord to horizontal tail ¼ chord distance Vertical and Horizontal Tail Sizes Overall Weight Project Proposal

    9. Design Strategies Incorporate Existing Design of RC and Full-Size World Estimate maximum loads Compare material and construction methods Matlab® Code developed for weight estimates Combine with structural evaluation code Manufacturing techniques and possibilities Design internal layout “Machine-to-Fit” approach 3D-CAD Systems Integration Design engine/wing attachment Project Proposal

    10. Construction Strategies Goal to Produce Precise Parts in Weight and Shape Traditional Wood Construction Modern Composite Fabrication Techniques Developed with AT482 Team Traditional Techniques in Use for Pattern A/C Split Part Female Molds (Wing, Fuselage) Machined Foam/Spar/Fiberglass Possible New “Seam-Less” Techniques Aluminum Sheets Male Molds Winding Techniques Project Proposal

    11. Examples for Wing Construction Pros Cons Project Proposal

    12. Project Timeline Project Proposal
