2. Introduction
The SAE Aero Design competition is designed to provide students with a real-life engineering experience. The team will be developing and constructing a heavy lift cargo plane. The design will exercise essential skills used in real-life applications. The Teams’ goal is to achieve an optimum design, while operating within the competition specifications.

3. Objectives
To design and build a Heavy Lift Cargo plane to compete in the SAE Aero Design East
Apply engineering experience
Making Compromises
Optimal design
Conforming to Configuration Limitations

4. Major Issues Involved
Choosing the proper airfoil that is easily constructed as well as providing the highest lift and necessary drag.
Designing proper wing flaps to stabilize control and functionality.
Designing a proper tail to optimize control and aerial performance.
Determining the proper angle of attack to insure takeoff.

5. Competition Selection
Examine/Choose a Class
Regular
Open
Micro
Regular Class
Designed to be simpler.
Lift the most weight while operating within design limits.
Open Class
Designed with less restrictions to allow a bigger solution set.
Micro Class
Designed to force the team to make compromises between two potentially conflicting requirements.
Carry the highest payload fraction while maintain the lowest empty weight possible.

6. 2007 Regular Class Requirements
Fixed Wing Aircraft
Wing Platform Limit: 1000 squared inches
Gross Weight Limit: 55 lbs
Payload bay Specs: 4x4x16 inches rectangular block
Single unmodified O.S. .61FX Engine with E-4010 Muffler
Max Take-Off: 200ft
Max Landing: 400ft
Highest Flight Score Wins

7. Flight Score Raw Weight Score = Weight lifted in pounds x 4
Flight Score = Raw Weight Score + Prediction Bonus + Empty Payload Bonus
Raw Weight Score = Weight lifted in pounds x 4
Prediction Bonus = 20 – (Predicted Payload – Actual payload)2
Empty Payload Bonus, 10 points available during Flight Round 1 only

8. Research Development
Research and communicate with experts in the field of aerospace engineering
Online research on methods of design and building of model planes
The use of computer software to design an airfoil and assist in the analysis of the airfoil

V-tail
Vertical tail
Wing dimensions.

15. State of the Art Considering the materials used:
Balsa wood
Composites
Aluminum
Foam
Different programs used to design relative parts of the plane: X-foil, Foilsim, WinFoil, Solidworks (COSMOSmotion and COSMOS Floworks)

16. The Ultimate Goals
Minimizing the weight while maximizing the strength.
Taking off within a distance less than 200 ft
Concentrating the center of gravity under the wings to ensure safe and stable cruising.
A unique cargo plane design.

17. Airfoil Selection Criteria
Sufficient coefficient of Lift CL (higher is better)
Ease of Construction
Previous successes and failures
Experimental Research (referencing online sources)

18. Airfoil Options Eppler 423 (CL=2.3) Selig S1210 (CL=2.1)
AQUILA (CL=1.148)

19. Airfoil Selection
Eppler 423 is our choice.
