  2. Overview • Purpose of Design Project and Requirements • Preliminary Design • Deliverables • Areas of Analysis • B+ vs. A Work Qualifications • Gantt Chart • Summary

  3. Purpose of Design & Requirements Primary Secondary • Design a canard aircraft that is comparable to the SR22 in performance • Conduct in-depth analysis on 5 areas of the aircraft • Use the analysis to evaluate the preliminary aircraft design • Roll Takeoff Distance: 1028 ft. • Climb Gradient: 864 ft/ nmi • Roll Landing Distance: 1141 ft. • Minimum Full Fuel Payload : 180 lb • Similar Loading Flexibility to the SR22 within Approved CG Limits • High Speed Cruise • Extended Range: 700 nmi • Increased Payload: 468 lb with fuel for this mission

  5. Preliminary Design Design Estimates

  6. Deliverable Design Groups • Integrated Aircraft Design Model • Landing Gear Design • Wing Configuration Design • Control Surface and Loading Stability Design • Canard Configuration Design Grades will be based on the depth of research and analysis and not dependent on meeting the requirements

  7. Integrated Aircraft Design Model • Using values obtained through initial sizing, construct a CAD model • Gather design specifications from individual groups for specific component design • Use these specifications to develop an integrated model of the final aircraft

  8. Deliverables: Aircraft Design B+ Work A Work • Full exterior CAD design of the original design • Full exterior CAD design of the optimized design

  9. Landing Gear Design Process • Stability Analysis based on CG and Mounting Locations • Determine Loading Cases • Tire Selection • Stroke Calculations for Landing Gear Damping • Initial Size Estimates and Stress Analysis • Modeling • Finite Element Analysis

  10. Deliverables: Landing Gear B+ Work A Work • Design a landing gear system • Tire Selection • Material Selection • Geometry Selection • Stress Analysis • CAD Model of Landing Gear • FEA of one landing gear structure • Suggestions for improvement • Show how it integrates to the entire design • Analyze interactions with rest of aircraft

  11. Wing Configuration Process • Select a Main Wing Airfoil and Design Planform • Determine All Relevant Aerodynamic Coefficients • Analyze Alterations and Customize Airfoil Shape and Size for Performance Optimization • Customized Sectioned Wing for Improved Stall Performance whycirrus.com/images/wing.jpg

  12. Deliverables: Wing Configuration B+ Work A Work • Design a sectioned wing • Fully analyze for : • Center of Pressure • Moment Coefficient • Lift Curve Slope • Span Wise Geometry (including wash out analysis)

  13. Controls and Loading Design Process • Main goal is developing the process for analyzing weight loading and stability capabilities. • Using weights, coefficients of lift, distances, and equations from individual groups to arrange the aircraft design for project requirements. • Develop Matlab coding and use ‘ball and stick’ moment and force approximations to conduct analysis.

  14. Deliverables: Controls and Loading B+ Work A Work • Calculate Weights and Moments • Control Surface Loading Limits • Show Loading and Stability Capabilities for Initial Aircraft Design • Compare Aircraft Capabilities with FAA Regulations • Compare Initial Aircraft with SR22 Capabilities • Show Loading and Stability Capabilities for Optimized Aircraft Design • Compare Optimized Aircraft Design with SR22 Capabilities

  15. Canard Configuration Process • Determine relationship between canard and other aspects of aircraft • Manipulate canard sizing to our benefit • Analyze flow interactions between the canard and the main wing www.manchesteruniversitypress.co.uk/uploads/docs/s2_10.pdf

  16. Deliverables: Canard Configuration B+ Work A Work • Design a Canard • Analyze interactions between the canard and wing • Calculate forces and moments on the canard • Optimize configuration for integrated aircraft • Fully Analyze: • Center of Pressure • Lift Curve Slope • Coefficient of Lift
