Introduction

• The team chose to compete in the Regular Class of the SAE Aero East Competition

• Team must design and build an airplane to lift the most weight

• All design and construction must be done by the students without professional help

Objectives• Design and build an airplane to successfully

compete in the SAE Aero East Competition• Plane must take off from within a 200 foot

runway and then land successfully on a runway of 400 feet

• Constraints of 55 total pounds and a height, weight, and length of 200 inches must be followed

Impact

• UAVs are becoming more prevalent in the military

• Project will provide model for future UAV production

• A design maximizing lift will allow for a better performing aircraft

Airfoil Concepts• Optimal Properties: Maximize

Lift, Minimize Drag• Researched a variety of airfoil

designs

• Decided on four concepts based on their high

coefficients of lift and low coefficients of drag:

Eppler 423, Selig 1223, NACA 8414, Wortmann FX 63-137

• Obtained values for CL and CD vs. AoA using airfoil modeling software

Airfoil Concepts (cont.)

• Airfoils measured in five categories• Each category weighted according to importance• Airfoils rated in all categories• Weighted composite of scores is totaled • Most points = Best airfoil for our needs

Wing Shape Concepts

• Three possible wing positions

• Straight, Dihedral, Swept

• Each shape gives unique control, stability and lift characteristics

Wing Shape Concepts (cont.)

• Wing shapes measured in four categories • Metrics – Lift, Ease of Construction, Stability,

Proven Success in past competitions• Lift and Stability of primary concern

Landing Gear Concepts

• 3 Concepts: Tail Dragger, Tricycle, Retractable

• Compared the weight, cost, durability, aerodynamics, ease of takeoff, and ease of landing

Tail Concepts

• Four Different arraignments analyzed– T-Tail– Cruciform– H-tail– V-tail

• Four categories the tail arraignments are analyzed for are, drag, ease of construction, stability, ground clearance

Tail Concept (cont.)

Deliverables

• Airplane design• Metrics used in concept selections• Detailed calculations• SOLIDWORKS/ANSYS models• Budget for the project• Analysis of design

BudgetExpected Budget for Plane

Total: $3,474

Project Schedule

Conclusion

• Create a competitive airplane design following the rules of the competition

• Use multiple resources to analyze design• Create and follow a clearly defined project

management schedule• Create an airplane with better capabilities
