Research Summary
This investigation explores the relationship between the surface area of a cambered airfoil and its resulting glide distance, analyzing the balance of lift and drag forces during unpowered flight.
Experimental Design
Data was collected using NASA's FoilSim simulation to model variations in lateral and frontal surface areas. These values were scaled to match the dimensions of a Boeing 787 to calculate theoretical glide ratios and distances.
Key Findings
The analysis indicates that scaling both frontal and lateral surface areas proportionally does not yield a significant change in glide range. To maximize aerodynamic efficiency and glide range, increasing the lateral surface area while maintaining a constant frontal area proved to be the most effective approach.
