1. Aero DesignOral Presentation Guidelines

   How to Deliver a Presentation The Judges will Notice SAE Aero Design Guidelines Rev A, 2013
2. Purpose This document has been prepared to give teams competing in the SAE Aero Design contests a better understanding of the elements judges expect to find in the Oral Presentation. This document is also intended to walk teams through the design process; by carefully reading this presentation, teams may discover key elements of aircraft design that can help them create better performing aircraft. SAE Aero Design Guidelines Rev A, 2013
3. Sample Outline Design Objectives Team Process Vehicle Sizing Configuration Selection Propulsion Structural Concept & Materials Stress Analysis Stability & Control Advance Class Flight Systems Performance Analysis Empirical Results SAE Aero Design Guidelines Rev A, 2013
4. Design Objectives Analyze the Relevant Scoring Formula Plot it, in Three Dimensions if Req’d Observe the Mission Parameters Note Any Special Requirements Wing Span Propulsion Limitations Succinctly State the Objective in Your Own Words SAE Aero Design Guidelines Rev A, 2013
5. Team Process Team Organization Work Breakdown Structure Schedule w/Key Milestones Conceptual Design Review Preliminary Design Review Critical Design Review Construction Flight Test SAE Aero Design Guidelines Rev A, 2013
6. Vehicle Sizing Determine Wing Loading, Planform Area Select Aspect Ratio  Span & Chord Select Airfoil Consider All Elements of Performance (CLmax, stall performance, drag) Consider Reasonable Building Constraints (such as trailing edge thickness) and their Impact Upon Performance SAE Aero Design Guidelines Rev A, 2013
7. Configuration Selection Conventional, Canard, Tailless Flying Wing, Delta, Biplane, Monoplane, etc. Analyze the pros & cons of each Select based upon best fit with design objectives Pay Attention to Requirements Tricycle or Taildragger Don’t Halt Analysis at Weight Only Consider the Operating Environment! Wing Placement: High, Mid, Low Consider Stability Implications Structural Implications Propulsion Installation SAE Aero Design Guidelines Rev A, 2013
8. Propulsion Advance Class Two or Four Stroke Size, Number of Engines Consider Torque Curves in Addition to Power Curves Micro Class (all electric class) Electric Propulsion System Choice/Analysis Reliability All Classes Propeller Selection—Don’t just use what the manufacturer recommends! Consider Dynamic Thrust, not just Static Thrust SAE Aero Design Guidelines Rev A, 2013
9. Structural Concept & Materials Build Accuracy Durability Schedule Constraints Weight Buildup Initial Estimates Final Results SAE Aero Design Guidelines Rev A, 2013
10. Stress Analysis Load Factor Factor of Safety Wing Strength Load Path for Payload In Flight During Landing Landing Gear If Your Design Includes “Flying Wires,” Include Them in the Analysis SAE Aero Design Guidelines Rev A, 2013
11. Stability & Control Static Margin Lateral/Directional Derivatives Dihedral, Polyhedral, or Flat? SAE Aero Design Guidelines Rev A, 2013
12. Advance Class FlightSystems Requirements Hardware/Software System Performance SAE Aero Design Guidelines Rev A, 2013
13. Performance Takeoff Distance Wind or No Wind? Why Consider Wind? If Wind, How Much? Payload Prediction State Prediction Under Most Likely Local Conditions Stopping Distance Assume a Reasonable Touchdown Point Remember You’re Dissipating Energy SAE Aero Design Guidelines Rev A, 2013
14. Empirical Results Results of Flight Test What Worked As Predicted What Didn’t, and Why Not What Was Changed as a Result SAE Aero Design Guidelines Rev A, 2013
