Project Description
This MSc project investigated the aerodynamic design of a fixed-wing Micro Air Vehicle (MAV) using analytical calculations, MATLAB and XFOIL. The objective was to optimise the wing configuration by evaluating aspect ratio, airfoil performance, lift-to-drag ratio and thrust requirements before selecting the final design.

My Role
I worked on:
- Developed MATLAB scripts to automate aerodynamic calculations and performance analysis.
- Used XFOIL to evaluate the aerodynamic characteristics of multiple NACA airfoils.
- Compared aspect ratios to minimise induced drag and improve aerodynamic efficiency.
- Selected the optimum wing configuration based on lift-to-drag ratio, drag coefficient and thrust requirements.
Aspect Ratio Optimisation
Different aspect ratios were evaluated to investigate their influence on induced drag. The study identified the optimum configuration by balancing aerodynamic efficiency and practical wing geometry.

Airfoil Selection
Seven NACA airfoils were evaluated using XFOIL to compare their aerodynamic performance. Drag polars and lift-to-drag characteristics were assessed to identify the most suitable airfoil for the final Micro Air Vehicle wing.
