A Performance-Based Parametric Design Exploration Tool for Student Aircraft Design Projects

Abstract

In this study, a performance-based calculation tool was developed to ease the process of exploring different conceptual aircraft conditions. The study aims to minimize human errors when calculating aircraft performance parameters manually. The parametric design tool, which will aid in designing unmanned aircraft, was built using Microsoft Excel. It was developed for the purpose of saving time and excessive effort that hand calculations require. Based on the criteria mentioned in the SAE aero design competition, five conceptual designs for the unmanned aircraft were drafted. One of the main criteria of this competition is creating an aircraft with a high payload fraction and a low empty weight. Using this Excel spreadsheet, we computed the values of thrust force, lift coefficient, drag coefficient, dynamic pressure, and drag force acting on the unmanned aircraft, allowing us to analyze and compare the performances of the different conceptual designs. To make sure that the Excel spreadsheet was reliable, it was tested and verified by comparing it with hand calculations.
