• Performed 5 ground vibration tests on very flexible aircraft resulting in natural frequencies and mode shapes being determined for different flight configurations with varying stiffnesses• Redesigned MATLAB script for postprocessing of data from ground vibration which resulted in fixing 5 major bugs that crashed script while achieving 50% faster runtime• Designed, built, tested, and documented new 3D printed bracket system for connecting aircraft to shaker for ground vibration testing, resulting in new bracket reducing setup time by 15 minutes• Tested aircraft during 2 test flights by injecting disturbance signals into the flight controller from ground station and collecting data for how autopilot corrected
