2. Overview  Objectives  Schedule  Progress  Design Concepts and Analysis –Wing –Fuselage –Tail –Landing Gear  Goals

3. Objectives  Competition Specs are finally posted for the 2004 competition  The plane meets the specifications of the 2004 SAE Aero Design West competition  Construct the plane to design specifications  Test the plane and make optimizations  To compete well at competition and improve Stevens reputation  For the team to improve and expand their knowledge of the design and construction of airplanes

4. Schedule

5. Rules Comparison Design Specifications: This Year (2004) Previous Year (2003) Wing Span Minimum 10 ft Maximum 6 ft Wing Chord No restriction Maximum 1 ft Planform Area No restriction Maximum 1200in 2 Cargo Volume Minimum 120 in 3 Minimum 300 in 3 Maximum Takeoff Distance 200 ft Maximum Landing Distance 400 ft Engine.61 FX-OS.61 FX-OS or K&B.61 R/C ABC Battery Minimum 500 mAh

6. Approach  Limited wing planform area  Limited lift force produced  Optimize: –Fuselage design –Materials used  Goal: –Minimum drag –Minimum weight  Unlimited wing planform area  Limited thrust force produced  Optimize: –Wing span –Fuselage design –Materials used  Goal: –Minimum weight 20032004

7. Design Achievements  Breaking down the plane into smaller components  Brainstorming different ideas for designs  Team divided into smaller groups  Areas studied in smaller group: –Selection of airfoil –Selection of wing shape –Tail stabilizer (both horizontal and vertical) –Landing gear analysis –Fuselage design  Detailed design of aircraft finalized

8. Calculation Achievements  Calculation of every component completed  Equations and resources from: – textbooks –online researching –white paper (Provided by SAE)  Calculations done with Excel Spreadsheet –Easy to link one value to another –Graphs were easy to compare which design is more efficient –Change around numbers  compare which aircraft design performs best upon constructing and testing  Results used in selection of airfoil, wing shape, and tail stabilizer  Calculations of Landing and Take-off

9. Sample Equations Landing Run Distance  Differential Equation of Motion  Landing ground runway  Coefficients A and B  Stall Velocity
