Design Objectives

  • Aerodynamic Efficiency: Provide sufficient lift while minimizing drag as the aircraft’s payload incrementally increases.
  • Stability: Provide predictable flight characteristics and maneuvering.
  • Structural Efficiency: Withstand expected weight aerodynamic inertial loads remaining lightweight and manufacturable. 
  • Rules Compliance: Aircraft must be a fixed wing with a span of 6-10ft. Composites not allowed.

 

Contributions

Driven by the mission requirements and wing objectives, I helped guide critical decisions on the aircraft configuration, sizing, airfoil, and wing design. I performed several trade studies that supported the selection of a high-wing, conventional-tail monoplane to maximize the mission score. I additionally contributed to the airfoil selection process, leading to the adoption of the S1223 RTL due to its strong aerodynamic performance across all key flight conditions including its high lift-to-drag ratio, gentle stall characteristics, and low pitching moment. Through simulations of multiple wing configurations in XFLR5, I identified a 10-ft tapered wing with an aspect ratio of 5 as the most aerodynamically efficient and statically and dynamically stable solution. I also designed the wing attachment points and wing structure consisting of a web, wood composite ribs, and stringers to be stiff, lightweight, and withstand shear and bending moments from aerodynamic inertial loads up to 4G’s.
