Aero Design Oral Presentation Guidelines

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
