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
Deliverables Airplane design Metrics used in concept selections Detailed calculations SOLIDWORKS/ANSYS models Budget for the project Analysis of design
Budget Expected Budget for Plane Total: $3,474
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 than previous Steven’s designs
